Department of Transportation February 19, 2010 – Federal Register Recent Federal Regulation Documents

The FAA amends digital flight data recorder regulations affecting certain air carriers and operators. This final rule prohibits the filtering of some original flight recorder sensor signals unless a certificate holder can show that the data can be accurately reconstructed. This final rule improves the integrity and quality of the data recorded on digital flight data recorders while giving aircraft designers and operators more flexibility in system design and operation where allowable.

We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-32R-301T and PA-46-350P airplanes. This proposed AD would require you to replace any spot- welded V-band exhaust coupling with a riveted V-band exhaust coupling. This proposed AD results from reports that spot-welded V-band exhaust couplings are failing. We are proposing this AD to prevent failure of the V-band exhaust coupling, which could cause the exhaust pipe to detach from the turbocharger. This failure could result in release of high temperature gases inside the engine compartment and possibly cause an in-flight fire. An in-flight fire could lead to loss of control.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

This notice announces the availability of the Final Environmental Impact Statement (FEIS) for the US-31 Holland to Grand Haven Project. This action is pursuant to the National Environmental Policy Act (NEPA) of 1969, 42 U.S.C. 4321 et seq, as amended and the Council on Environmental Quality Regulations (40 CFR Parts 1500-1508). The FEIS identifies the Preferred Alternative which proposes improvements to US-31 from East Lakewood Boulevard north to Quincy Street, in Holland; and from south of Franklin Street north to north of Jackson Street in Grand Haven. The new M-231 route would be constructed west of 120th Avenue, from M-45 (Lake Michigan Drive) north to the I-96/M-104 interchange, including a new crossing of the Grand River; improvements to M-104, near I-96; new ramps at the I-96/M-231 interchange; and improvements to the I-96/112th Avenue interchange.
