2.2.1 NASA aircraft shall be operated in an airworthy condition as certified by a formal NASA airworthiness review board (ARB), under the authority of a NASA Center Director, using a NASA Certificate of Airworthiness process. 
188.8.131.52 All NASA aircraft shall possess and maintain a NASA Certificate of Airworthiness (Appendix F) approved by the Center Director.  For all NASA aircraft other than NASA-owned aircraft, the certificate shall state the duration of applicability, as well as any limitations of that certificate.  A NASA Certificate of Airworthiness is valid only when conducting a NASA mission.
184.108.40.206 All aircraft used for passenger transportation purposes shall possess a “Normal” or “Transport” category FAA Certificate of Airworthiness. 
220.127.116.11 When NASA aircraft are transferred between Centers, a new NASA Certificate of Airworthiness approved by the receiving Center Director shall be obtained prior to commencing flight. 
2.2.2 Airworthiness, flight safety, and mission readiness reviews, including configuration control, shall be conducted for all aircraft modifications, with the exception of those noted in section 18.104.22.168 that are cleared through an airworthiness review process (ARP) or configuration control process.  These review processes are to clear unique or nonstandard internal or external payloads or stores configurations for flight and to review nonstandard flight operations—those other than normal aircraft operations for the specific aircraft. The purpose of these reviews is to identify hazards so as to minimize risks to persons and property and to enhance the likelihood of mission and program success. Formal review requirements will be appropriate for the types of modifications incorporated, the specific mission or project requirements, and the operational risks involved.
2.2.3 The ARP may include several levels of review. Each Center shall clearly identify the appropriate airworthiness review process for experimental, research, and operational configurations and nonstandard ground or flight operations for all aircraft operated by the Center. 
2.3.1 The Chief, Safety and Mission Assurance formulates NASA safety policy and provides independent oversight of NASA aviation safety and safety procedures or guidelines.
2.3.2 Center Directors shall establish airworthiness, flight safety, mission readiness, and configuration control review processes and procedures to identify any hazards, to manage the risks associated with flight programs, to ensure safe flight operations, to manage and thoroughly document aircraft configurations, and to ensure that flight objectives satisfy programmatic requirements.  Center Directors shall ensure that these review processes and procedures are incorporated into the contracts of those who operate and maintain NASA aircraft. 
2.4.1 Center Directors shall establish procedures to ensure that airworthiness and safety reviews are conducted for flight operations or missions. 
22.214.171.124 Reviews shall ensure that hazards associated with aircraft experimental modifications, research, or unique internal or external payloads and nonstandard operations are identified and that risks are adequately managed to enhance the likelihood of mission and program success for all aircraft missions or operations and to minimize the risks to persons or property. 
126.96.36.199 Program managers shall review flight programs early in the development cycle to identify the need and schedule for additional safety-related resources, procedures, or reviews. 
188.8.131.52 Managers shall ensure that aircraft modifications are accomplished with sufficient time for engineers and technicians to safely complete required tasks. 
184.108.40.206 Center Directors shall establish configuration control procedures to ensure that the configuration of each NASA aircraft is fully documented and reviewed.  Waivers to a minimum equipment list (MEL) may be granted by the Chief of Flight Operations but may not be delegated to a lower office/position.
220.127.116.11 Center Directors shall establish a MEL for all non-test-related equipment for all aircraft operations.  Waivers to a MEL may be granted by the Chief of Flight Operations but may not be delegated to a lower office/position.
18.104.22.168 Test-related equipment will be handled through the flight test planning process. If test equipment remains on the aircraft for non-test-related missions, then such equipment shall be addressed in the aircraft MEL.  Waivers to a MEL may be granted by the Chief of Flight Operations.
2.4.2 The ARP is the process by which engineering and safety analyses are reviewed to determine that an aviation system or its component parts meets minimum design criteria, standards, and configuration for the conduct of safe flight operations. The ARP also includes a review of the operations of NASA aircraft when those operations are nonstandard for that aircraft type, place the aircraft into a more hazardous environment than normal, or involve experimental internal or external payloads, configurations, or noncertified external stores, including the dropping of uncertified stores, which may affect the airworthiness of the aircraft.
22.214.171.124 An ARP is required prior to an aircraft commencing its first or subsequent test or research flights in nonstandard configurations or operating envelopes. An ARP approval is valid only for the specific configurations and flight envelopes and operations specified in the approval. Any change to the specified configuration or flight operation requires issuance of a separate or amended ARP approval per individual Center procedures.
126.96.36.199 Examples of configuration and envelope changes requiring an ARP approval include, but are not limited to:
a. Structural and material changes that alter the basic aircraft design configuration.
b. Modification of the exterior contour or mold line of the aircraft to an experimental configuration (e.g., addition/removal of wing fence, ventral fin, vortex generator, air induction system, auxiliary inlets, and nonstandard antenna configurations or locations).
c. Modification to the flight control system, including software revisions, to nonstandard configurations.
d. A new or modified propulsion system or its control system, including software revisions, that is nonstandard for the aircraft.
e. Modification of the displays or annunciation affecting critical information presented to the aircrew (e.g., situational awareness, aircraft control, air vehicle launch) that are nonstandard for the aircraft.
f. Modification of any subsystem interfacing with and affecting flight or propulsion systems (e.g., mission computer, navigation, and warning and caution systems) that are nonstandard.
g. Modification of the aircrew life support systems to nonstandard configurations.
h. Evaluation of crosswind landing or wet runway landing limits, emergency procedures, structural or flight control limits, wind envelopes, or helicopter external lift, cargo hook system, or tow limits that are outside the normal limits for the aircraft.
i. Flight test instrumentation that interfaces with normal aircraft systems or that may affect the operation of those systems.
j. Intentional operation in a degraded mode for test purposes (e.g., simulation of partial loss or malfunction of flight control system, engine, and avionics).
k. Dropping of uncertified stores or objects.
l. Any other modifications, payloads, or operations that are nonstandard according to established flight manuals, procedures, or FAA certification requirements (if operated under an FAA airworthiness certificate).
188.8.131.52 Minor aircraft system modifications that do not interface with or affect the standard operation of aircraft systems or alter aircraft aerodynamic characteristics may be reviewed through a configuration control process. Examples of modifications that might fall into this category include such systems as:
a. Additions of C-band tracking beacons.
b. Addition of onboard video-recording equipment.
c. Addition of global positioning system (GPS) recording or tracking systems.
184.108.40.206 The following aircraft modifications may not require airworthiness certification, flight safety, or mission readiness reviews:
a. Airworthiness Directives, commonly issued by FAA.
b. Maintenance Advisories, which are issued by multiple sources, such as the U.S. Navy, the U.S. Air Force, and manufacturers.
c. One Time Inspections (OTI), which may be issued by multiple sources.

220.127.116.11 Modifications to aircraft, such as avionics upgrades, that meet FAA certification requirements, according to applicable FAA regulations, may be handled through a configuration control process.
2.5.1 Each Center Director shall ensure that the ARP is staffed with personnel possessing the appropriate scientific, engineering, operational, maintenance, and managerial expertise, including at least one NASA pilot and the ASO. 
18.104.22.168 The process reviews project or mission hazards, aircraft modifications, project processes, and procedures related to safety and mission assurance. In addition, the process approves appropriate risk mitigation procedures/techniques and provides oversight for all planned operations.
22.214.171.124 Each Center Director is responsible for establishing a list of senior managers and/or senior engineers who are responsible for conducting the ARP and approving projects or missions for flight, including appointing personnel responsible for managing and executing the Center ARP review board and maintaining records of airworthiness approvals.
2.5.2 The ARP review board may be broken down into several subpanels to facilitate the overall review process. For instance, separate reviews of technical issues and safety hazards may facilitate a detailed review of specific aspects of the project or mission by discipline experts, who then advise the Center review board. Any cockpit or cabin modifications that might interfere with aircrew egress shall be reviewed by a subpanel, including aircrew and life support personnel. 
2.5.3 The ARP approval for flight may be for an entire test or research program or be restricted to a certain number of flights or missions and require additional review once defined project or mission goals are achieved.
2.5.4 The ARP shall be continual throughout the course of a project.  The Center Director may establish periodic reviews to review project progress subsequent to defined project events (including successes or failures) or at other points in the project to review the overall airworthiness of the aircraft for the intended mission, as well as the progress of the project.
2.5.5 Each Center shall establish the content of the ARP based on the aircraft mission, complexity of the modifications, and the inherent hazards associated with the operation. 
126.96.36.199 Content for ARP approvals shall be documented in Center-level ARP procedures.  The following are typical of the information required for an ARP to approve an aircraft modification or flight operation for a specific aircraft configuration:
a. A description of the aircraft modifications, including aircraft configuration, loads, flight envelope, aircraft weight and balance data, reference to applicable mechanical and electrical design documents, reference to applicable software version description documents, and a listing of associated computer software configuration. The ARP reviews each of these items as applicable for the specific aircraft or subsystems under review.
b. Applicable engineering analyses that describe design criteria, aircraft loads and safety limits, external pod loads, electrical or mechanical system vibrations, aero-elastic vibrations (flutter), aero-servo-elastic effects, thermal loads, electrical system loads, and other abnormal environmental conditions and their effects on aircraft performance, stability, and control or aircraft systems operation. The results of tests conducted to verify the engineering analyses also shall be considered. 
c. A description of the required flight operations, including operating procedures, test conditions, maneuvers, required instrumentation, mission control operations, mission rules and flight limitations, nonstandard operation or inspection criteria, and associated checklists. Actions to be taken in the event of in-flight malfunctions or emergency conditions associated with the aircraft modifications or nonstandard operations also shall be described. 
d. A safety hazard analysis of systems and operations, including risk assessment and risk reduction actions and the methodology used to reduce the risks to acceptable levels (design, safety devices, warnings, procedure or training, or other methods).
2.5.6 ARP approval is based on the results of Center-approved engineering and safety analyses. The final approval shall contain a description of the configuration of the aircraft, operating instructions and procedures, operating limitations and restrictions, and specific maneuvers or operations for which the aircraft is cleared. 
2.6.1 The objective of an effective maintenance program is to ensure that assigned aircraft are serviceable (safe and operable) and properly configured to meet mission requirements in the most cost-effective manner. This is accomplished by performing maintenance, inspection, repair, overhaul, modification, preservation, testing, and condition or performance analyses. Emphasis is placed on processes that reduce the risk of a maintenance failure and the associated impact on operations. The Chief of Flight Operations is responsible for maintaining the airworthiness of aircraft assigned to the Center. The airworthiness of the aircraft includes airframes, engines, propellers, rotors, appliances, and parts. All maintenance and inspections shall be performed in accordance with this chapter and the applicable manufacturers’ manuals as appropriate. The Center’s Chief of Maintenance is the focal point for all Center aircraft maintenance activities and will ensure that discrepancies between required inspections are corrected to maintain continued airworthiness.
2.6.2 NASA aircraft shall be maintained in accordance with an established and documented Center maintenance program, using standards of quality in workmanship, materials, and support equipment that will ensure airworthiness of aircraft for safety of flight.  All NASA aircraft shall be maintained in a condition for safe operation and meet their respective type designs or properly altered condition.  It is essential that the continued airworthiness of NASA aircraft be consistent with the terms of the Airworthiness Certificate. A maintenance program shall meet FAA regulations for any passenger-seating capacity for an aircraft that is used for passenger transportation.  Documentation is an essential part of maintenance with the objective of providing timely, accurate, and complete information to the Chief of Flight Operations. Use of the NASA standard maintenance application, NASA Aircraft Management Information System (NAMIS) is mandatory.
2.6.3 Depot-Level or Major Aircraft Modifications
188.8.131.52 Center Flight Operations shall maintain continuous onsite oversight of vendors and facilities performing aircraft depot-level overhauls or major aircraft modifications to ensure quality of workmanship, adherence to NASA standards, schedule, and cost control.  This oversight function may be performed only by NASA employees or contractors that are independent of the vendor facility to reduce any conflict of interest.
184.108.40.206 Individuals assigned onsite responsibilities shall have expertise and experience in aircraft airworthiness standards and requirements. 
220.127.116.11 For maintenance performed outside of NASA, the Chief of Maintenance shall ensure that:
a. The person(s) performing the maintenance, preventive maintenance, or alteration is properly certificated and qualified to perform the assigned function. 
b. The work performed is done in accordance with the NASA-approved continuous airworthiness program and/or FARs. 
c. A record is made in the aircraft log book of the description of work performed, the date, certificate number, and type of certificate held by the person performing the work. 
2.6.4 The NASA process for a continuous airworthiness maintenance program is a compilation of the individual maintenance and inspection functions. These specifications prescribe the scope of the program, including limitations, and the reference manuals and other technical data as supplements to these specifications. The following are the basic elements of a continuous airworthiness maintenance program:
a. Aircraft Inspection: This element deals with the routine inspections, servicing, and tests performed on the aircraft at prescribed intervals. It includes detailed instructions and standards (or references thereto) by work forms, job cards, and similar documents, which also serve to control the activity and to record and account for the tasks that comprise this element.
b. Scheduled Maintenance: This element concerns maintenance tasks performed at prescribed intervals. Some are accomplished concurrently with inspection tasks that are part of the inspection element and may be included on the same form. Other tasks are accomplished independently. The scheduled tasks include replacement of life-limited items, components requiring replacement for periodic overhaul, nondestructive inspections, checks or tests for on-condition items, lubrications, and similar activities.
c. Unscheduled Maintenance: This element provides procedures, instructions, and standards for accomplishing maintenance tasks generated by the inspection and scheduled maintenance elements, pilot reports, failure analyses, or other indications of a need for maintenance.
d. Engine, Propeller, and Appliance Repair and Overhaul: This element concerns shop operations, which, although they encompass scheduled and unscheduled tasks, are remote from maintenance performed to the aircraft as a unit. Appropriate life-limited parts replacement requirements are included in this element.
e. Structural Inspection Program/Airframe Overhaul: This element concerns the structural inspections identified as the C and D check level by the manufacturer, airframe major overhaul, major corrosion inspections, Programmed Depot Maintenance (PDM), and Scheduled Depot Level Maintenance (SDLM) or similar inspections. In addition to structural inspection, major airframe overhaul programs require extensive maintenance scheduling.
f. Required Inspection Items: This element concerns maintenance work items, which, if improperly done or for which improper parts are used, could endanger the safe operation of the aircraft. Required inspection items appear in all elements of the operator’s continuous airworthiness maintenance program.
2.6.5 Each Center shall develop written maintenance procedures and practices in a Center’s maintenance manual that supports the aircraft-specific (manufacturer, NASA, or DoD) maintenance programs.  While this maintenance program may be completed by contractor maintenance, the contractor is required to follow the Center maintenance manual whose accuracy and currency shall be the responsibility of the Chief of Maintenance.
18.104.22.168 The Center’s maintenance manual serves to define the continuous airworthiness maintenance program and to provide procedures and instructions for its use. A comprehensive maintenance plan will be detailed in the Center’s maintenance manual and include a list of specific maintenance processes. At a minimum, the following shall be included:
a. A description of how aircraft log books and associated records for assigned aircraft and components are maintained.  Maintenance of aircraft log books is essential to ensure the airworthiness of aircraft. Aircraft log books, whether electronic or on paper, provide a history of maintenance, operation, and configuration control of aircraft. Persons signing entries in the aircraft log book and/or entries on serviceable parts tags shall:
(1) Be authorized in accordance with NASA requirements and applicable Federal Aviation Regulations (FARs) and have satisfactorily completed maintenance training or possess the equivalent current experience on the applicable type appliance, aircraft, engine, or propeller.

(3) Meet Center-defined certification processes. 
b. A documented aircraft release procedure that ensures that all maintenance release authorities are designated in writing.  Additionally, there shall be a documented aircraft release process for aircraft that are deployed from the Center.  If required, the Chief of Maintenance will designate the maintenance release authority in writing for aircraft deployed from the Center.
(1) Any individual with maintenance release authority shall have at least six months experience during the preceding 24 months in the inspection, servicing, or maintenance of an aircraft or system, in accordance with Center maintenance procedures. 
c. Written ground handling procedures that may be accomplished only by qualified ground handling personnel to perform fire guard, application of external electrical power, towing, engine run, and taxi operations that document aircraft-specific training and designate those qualified in writing. 
d. A documented Metrology and Calibration (METCAL) program that establishes policy, responsibilities, and requirements to ensure that calibrated and tested tools/special equipment performance is compared to referenced calibration standards (CALSTDs) of known and sufficiently greater accuracy.  Calibration ensures that only currently calibrated and tested tools/special equipment operating within established tolerance limits are used to perform maintenance on an aircraft.
e. A documented foreign object damage (FOD) control program that addresses the periodicity and inspection criteria and effectively reduces the risk of FOD both during maintenance and flight operations.  The FOD Prevention Program establishes policy, responsibilities, and requirements to prevent damage to aircraft, engines, ground support equipment (GSE), and other aeronautical equipment and provides uniform FOD reporting procedures. All flight operations personnel and employees shall be constantly on lookout for material that could be ingested into engines, struck by propeller blades, and/or blown by the exhaust of engines or propellers, causing injury to personnel or damage to aircraft.  Maintenance personnel shall be assigned to perform a general inspection of hangar and ramp areas for FOD on a weekly basis at a minimum. 
f. A documented tool control program (TCP) that ensures the accuracy of tool inventories at specific intervals, contains a lost tool process, and prohibits aircraft from flying until all tools used on an aircraft have been accounted for.  The TCP establishes policy and responsibilities for implementing, maintaining, controlling, storing, replacing, and inventorying common hand tools. The TCP is applicable to all NASA activities performing or supporting aircraft maintenance. The TCP shall apply to all commercial and Government activities performing contract maintenance, production, or other support functions on NASA aircraft.  This program shall provide instant inventory capability.  The primary objectives of the TCP are enhancing safety by eliminating accidents and equipment damage attributed to uncontrolled tools and minimizing tool replacement costs. An effective TCP is the responsibility of all maintenance personnel and all levels of the chain of command.
g. A documented process to ensure that all GSE used on aircraft are safe and operable.  GSE shall be maintained per written requirements that document how to identify and remove equipment that is unserviceable.  GSE includes all equipment used to make an aeronautical system or end item operational in its intended environment. GSE shall be maintained and documented under an aviation maintenance system or other NASA-approved system. 
h. Maintenance procedures and technical standards for Aviation Survival Equipment (including life support and ejection seats) for the equipment being flown, which are an integrated function of aircraft maintenance.  If the Center maintains explosive devices (propellant actuated devices (PADs)/cartridge-actuated devices (CADs)), the Center maintenance manual shall document the program for personnel training and qualifications.  All tools shall be accounted for after the repack and inspection of each item. For example, parachutes and floatation equipment, since these items cannot be functionally checked prior to use. 
i. A documented confined space program that defines all aircraft confined spaces and ensures safety in these spaces prior to entry per NPR 8715.3, NASA’s General Safety Program Requirements.  The objective of the Aircraft Confined Space Program is to ensure that a safe environment is maintained when working on aircraft fuel cells, tanks, and service areas.
j. A documented program that ensures that aircraft maintenance complies with Center Electromagnetic Interference (EMI)/Electrostatic Discharge (ESD) programs.  The EMI/ESD control program establishes policy, responsibilities, and requirements for EMI prevention and reporting and the handling, transportation, storage, and maintenance of ESD-sensitive devices/components. Improper handling, transportation, and storage techniques can cause electrostatic-sensitive devices and components to fail. The insidious nature of ESD-induced failures requires ESD control protection measures to be integral parts of aviation maintenance and supply disciplines. All solid state electronic components and assemblies containing such components are considered ESD-sensitive items, unless otherwise directed by higher authority. These items include printed circuit board assemblies, line replaceable units (LRUs), individual components, and integrated circuits.
k. A Fuel Surveillance Program that ensures that fuel is free of contaminants prior to fuel entering any Center aircraft.  The Fuel Surveillance Program establishes policy, responsibilities, and requirements for implementing procedures to maintain aircraft and engine fuel systems’ purity. The Fuel Surveillance Program applies to all NASA aircraft, engines, and test cells to include outside vendor-supplied fuel.
