AIR's functions include issuing initial and amended type certificates for designs for new aircraft, issuing supplemental type certificates (STCs) for designs of modifications to existing aircraft, issuing production certificates to certify a manufacturer's ability to build an aircraft in accordance with an approved design, and issuing airworthiness certificates to verify that individual aircraft have been manufactured in accordance with approved designs and are in safe operating condition.

From page 11... ...
A design for a multi-engine, propeller-driven airplane with 19 or fewer seats (excluding seats for the flight crew) and a maximum certificated takeoff weight of 19,000 pounds or less must be type certificated as a "commuter category airplane" under FAR 23 unless it is certificated under Part 25.

From page 12... ...
The descriptors used in the aircraft certification regulations only define the airworthiness standards applicable to the design of the aircraft, whereas the descriptors used in the operating rules define the specific operating rules that apply. For example, an aircraft type certificated as a "transport category airplane" under Part 25 may or may not be intended for use in air transportation service by an "air carrier" under Part 2Type certification basis is described below in the section on initial type certification.

In summary, the court's opinion clarified that the FAA's authority and duty to promote aviation safety through regulation is defined by FARs, whereas the degree to which the FAA exercises oversight authority, especially in areas such as aircraft certification and continued airworthiness, depends to a great extent on the resources allocated by Congress in annual appropriations.

in the Convention on International Civil Aviation, to which the United States is a signatory.5 For a civil aircraft to receive an airworthiness certificate, the FAA must determine that the aircraft conforms in detail to an FAA-approved type design and is in safe operating condition. Similar requirements exist for engines, propellers, and certain materials, parts, and equipment installed on certificated aircraft.

For example, the Douglas DC-9-30 is one of several derivative aircraft designs based on the original DC-9 type design (the DC-9-10. The type certification basis for a derivative type design is the type certification basis for the original type design, as modified by special conditions issued to address novel and unusual design features in the derivative design that are not adequately addressed by the original type certification basis.

AIR's activities to promote the continued airworthiness of the operational fleet of civil aircraft include the following: participating in accident and incident investigations · reviewing and analyzing reports of in-service difficulties that might reveal the existence of unsafe conditions reviewing safety recommendations made by the National Transportation Safety Board (NTSB) that relate to aircraft certification reinvestigating design approvals for compliance with design certification standards, as necessary auditing production quality control systems to verify continued compliance with the terms of production certificates and approvals initiating enforcement actions, which may include civil penalties and/or suspending or revoking certificates issuing ADs (see below and the section on Risk Management/Action in Chapter 4)

In those cases, the IMPROVING THE CONTINUED AIRWORTHINESS OF CIVIL AIRCRAFT holder of the type certificate may submit appropriate design changes for FAA approval. Upon approval, the manufacturer makes relevant service information available to operators.

This staff was distributed over 34 geographical locations. Activities completed by AIR during fiscal year 1997 included the following: 25 type certificates approving the designs of new aircraft, aircraft engines, and propellers 110 amendments to existing type certificates approving the designs of new derivative models of aircraft, aircraft engines, and propellers 1,011 new STCs approving designs for modifications to products approved by preexisting type certificates

From page 20... ...
2,473 production certificates and other production quality control system approvals 1,840 original airworthiness certificates issued to newly manufactured aircraft 341 ADs to correct safety problems in existing aircraft 790 appointments of new designees to act as "representatives of the administrator" for design approvals and airworthiness certifications final action in response to 31 petitions for exemption final action in response to 14 petitions for rulemaking The FAA as a whole published 19 NPRMs and issued 29 final rules. RELATED ACTIVITIES Unapproved Parts Unapproved parts are parts that have not been approved under applicable FARs or have lost their approval status because of a change in condition caused by damage, wear, etc.
