On average, accident-involved public use aircraft pilots were more highly qualified than accident-involved GA accident pilots, holding more advanced flight certificate ratings, according to the data reviewed by the NTSB.
c. Statutory Text. The new definition of public aircraft enacted by Congress is as follows:
"(1) an aircraft -
(i) used only for the United States Government; or
(ii) owned and operated (except for commercial purposes) or exclusively leased for at least 90 continuous days by a government (except the United States Government), including a State, the District of Columbia, or a territory or possession of the United States, or political subdivision of that government; but
(2) does not include a government-owned aircraft -
(i) transporting property for commercial purposes; or
(ii) transporting passengers other than -
(A) transporting (for other than commercial purposes) crewmembers or other persons aboard the aircraft whose presence is required to perform, or is associated with the performance of, a governmental function such as firefighting, search and rescue, law enforcement, aeronautical research, or biological or geological resource management; or
(B) transporting (for other than commercial purposes) persons aboard the aircraft if the aircraft is operated by the Armed Forces or an intelligence agency of the United States.
3) An aircraft described in the preceding sentence shall, notwithstanding any limitation relating to use of the aircraft for commercial purposes, be considered to be a public aircraft for the purposes of this part without regard to whether the aircraft is operated by a unit of government on behalf of another unit of government, pursuant to a cost reimbursement agreement between such units of government, if the unit of government on whose behalf the operation is conducted certifies to the Administrator of the Federal Aviation Administration that the operation was necessary to respond to a significant and imminent threat to life or property (including natural resources) and that no service by a private operator was reasonably available to meet the threat."
49 U.S.C. 40102(a)(37).
The status of an aircraft as "public aircraft" or "civil aircraft" depends on its use in government service and the type of operation that the aircraft is conducting at the time. Rather than speaking of particular aircraft as public aircraft or civil aircraft, it is more precise to speak of particular operations as public or civil in nature. Example: An aircraft owned by a state government is used in the morning for a search and rescue mission. During the search and rescue operation, the aircraft is a public aircraft. Later that same day, however, the aircraft is used to fly the governor of the state from one meeting to another. At that time, the aircraft loses its public aircraft status and must be operated as a civil aircraft.
(i) the Administrator finds that granting the exemption is necessary to prevent an undue economic burden on the unit of government and
(ii) the Administrator certifies that the aviation safety program of the unit of government is effective and appropriate to ensure safe operations of the type of aircraft operated by the unit of government.
"The Administrator Finds ... and ... Certifies." This language indicates that the Administrator, or his or her delegate, is to make an independent determination as to whether the statutory requirements for granting an exemption have been met. This is in contrast to an earlier portion of the statute in which the unit of government rather than the Administrator makes the required certifications (that the operation was necessary to respond to a significant and imminent threat, and that no private operator was reasonably available to meet the threat).
"Undue Economic Burden." One finding that the Administrator or his or her delegate must make before granting an exemption is that the exemption is necessary to prevent an undue economic burden on the unit of government. "Undue economic burden" means that it would cost substantially more to comply with FAA regulations than with "an aviation safety program that is effective and appropriate to ensure safe operations of the type of aircraft operated by the unit of government" under the statute's exemption provision. To show "substantial additional costs," a petitioner for exemption should submit information that will allow the FAA to compare the cost of operating in compliance with Part A of Subtitle VII of Title 49 of the United States Code with comparable costs if an exemption were granted.
"Aviation Safety Program." The Administrator or the Administrator's delegate may not grant an exemption to a unit of government without certifying that the aviation safety program of the unit of government is "effective and appropriate to ensure safe operations of the type of aircraft operated by the unit of government." As a result, in the petition for an exemption, the petitioner must show to the Administrator's satisfaction that the petitioner's aviation safety program is effective and appropriate to ensure safe operations of the type of aircraft operated by the petitioner. Example: A unit of government applies for an exemption on an aircraft whose wings were modified to carry external pods for various surveillance activities. In its proposed aviation safety program, the unit of government would need to identify how the continued airworthiness of the modification will be accomplished. At minimum, the following may be required: a special structural inspection at the wing attach points, additional training for pilots operating the aircraft during pod installations, and flight manual changes to reflect any new operating limitations that may be necessary due to the modifications.
Aircraft with No Previous FAA Type Certification. It may be difficult for units of government to show that, for aircraft having no previous FAA type certification, e.g., military surplus aircraft, they have "an aviation safety program that is effective and appropriate to ensure safe operations of the type of aircraft operated by the unit of government." In order to make the "effective and appropriate aviation safety program" finding, the FAA must be assured that the safety of the aircraft in question is comparable to that provided by the FAR. Aircraft that have no history of civil certification often present significant "unknowns" when it comes to such critical safety matters as life-limited parts and aircraft design. Thus, such aircraft often do not have the basis on which to build an aviation safety program that is effective and appropriate to ensure safe operations. A unit of government developing a proposal for an aviation safety program may find the information below helpful:
Generally. Subpart E of FAR Part 91 prescribes the rules governing the maintenance, preventative maintenance, and alterations of U.S.-registered aircraft civil aircraft operating within and outside the United States. FAR Section 91.403 states that the owner or operator of an aircraft is primarily responsible for maintaining that aircraft in an airworthy condition, including compliance with FAR Part 39. FAR Part 39 describes the requirements for compliance to AD's issued by the FAA.
Inspection Programs. Operators of large aircraft, turbojet multiengine airplanes, or turbopropeller powered multiengine airplanes, should select and use one of the four inspection program options outlined in FAR Sections 91.409(e) and (f).
For one of the four inspection program options, that identified in FAR Section 91.409(f)(4), the inspection program submitted should be compared with the manufacturer's recommended program. Where there is no manufacturer's program, a time-tested program should be utilized. The program developed must provide a level of safety equivalent to or greater than that provided by the other inspection options identified in FAR Section 91.409(f).
For the other three inspection options outlined in FAR Sections 91.409(e) and (f), the basis for the development of the inspection program or the instructions for continued airworthiness, including the detail of the parts and areas of the airplane to be inspected, is the manufacturer's recommendations. In the case of surplus military aircraft, the manufacturers provide this basic information to the specific military service that has contracted for the airplane. The military service then develops a reliability-centered maintenance program to meet its needs and environment which are often comparable to the continuous airworthiness maintenance programs developed by air carriers.
In many cases, manufacturers may be unwilling or unable to provide instructions for continued airworthiness for operation of the airplane in other than a military environment. Therefore, in keeping with existing policy as provided by the FAA, the only reasonable basis that for detailing the inspection criteria for the aircraft to be inspected, as required by FAR Section 91.409(g)(1), is the scope and detail developed by the applicable military service.
In addition to the "field" level inspection requirements set forth in the military maintenance program, the "depot" level inspection requirements should also be included in any inspection program approved under FAR Section 91.409(f)
The military "field" level maintenance is roughly equivalent to the civil terminology that air carriers use to describe "A, B or C" checks. The military "depot" level maintenance is comparable to the "heavy C or D" checks used by air carriers. Some air carriers may use a numerical description verses the alphabetical identifier for inspection checks.
The inspection frequency and program structure established by the military may not be appropriate for use in a civilian environment. Therefore, inspection frequency and program structure may require adjustment to meet the government operator's requirement. However, facts and sound judgment must form the basis for any inspection frequency adjustment beyond that which has been established for use by the military.
An alternate means of compliance for individual specific inspection requirements, in lieu of that which is called for in the military "field" or "depot" level programs, may be approved following evaluation of the applicant's inspection process instructions.
Revisions to an operator's existing approved inspection program can be requested by the Administrator in accordance with FAR Section 91.415.
Persons Conducting Inspections and Maintenance. The program proposed by the petitioner should include procedures to insure that inspections and maintenance tasks are performed by persons authorized by FAR Sections 43.5 and 43.7.
Modifications and Repairs. The program must identify all major modifications and repairs accomplished since the aircraft was put into service. Additionally, all further modifications and major repairs will need to be approved in the same format as required for civil aircraft under the regulations.
