Department of Transportation November 22, 2011 – Federal Register Recent Federal Regulation Documents

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. Information is collected from applicants who wish to obtain repair station certification. Applicants must submit FAA form 8310-3 to the appropriate FAA flight standards district office for review.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. 14 CFR part 298 requires air carrier operators to obtain a certificate of public convenience and necessity from the DOT, with the exception of air taxi and commuter air operators.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The information is collected from holders of FAA production approvals and selected suppliers to obtain their input on how well the agency is performing the administration and conduct of the Aircraft Certification Systems Evaluation Program (ACSEP).

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. Non-Federal navigation facilities are electrical/electronic aids to air navigation which are purchased, installed, operated, and maintained by an entity other than the FAA and are available for use by the flying public.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 214/EUROCAE WG-78: Standards for Air Traffic Data Communication Services.

We propose to supersede an existing airworthiness directive (AD) that applies to all Pratt & Whitney (PW) JT9D series turbofan engines. The existing AD currently requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. Since we issued that AD, PW has added mandatory inspections for certain critical life-limited parts. This proposed AD would require additional revisions to the JT9D series engines ALS sections of the manufacturer's ICA. This proposed AD results from the need to require enhanced inspection of selected critical life-limited parts of JT9D series engines. We are proposing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

We propose to revise an existing airworthiness directive (AD) that applies to TAE models TAE 125-01 and TAE 125-02-99 reciprocating engines installed on, but not limited to, Diamond Aircraft Industries Model DA 42 airplanes. The existing AD currently requires initial and repetitive replacements of proportional pressure reducing valves (PPRVs) (also known as propeller control valves). Since we issued that AD, TAE has increased the life of the PPRV, part number (P/N) 05-7212- E002801, on TAE 125-02-99 engines, from 300 hours to 600 hours. This proposed AD would relax the repetitive replacement interval from a 300- hour interval to a 600-hour interval for PPRVs, P/N 05-7212-E002801, on TAE 125-02-99 engines. We are proposing this AD to prevent engine in- flight shutdown, possibly resulting in reduced control of the aircraft.

These special conditions are issued for the Diamond Aircraft Industries, Model DA-40NG airplane. This airplane will have a novel or unusual design feature(s) associated with an electronic engine control (EEC) also known as a Full authority Digital Engine Control (FADEC). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
