Federal Aviation Administration August 19, 2008 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:

We are revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. The original NPRM would have required a one-time general visual inspection of frames between body station (BS) 360 and BS 907 to determine if certain support brackets of the air conditioning (A/C) outlet extrusions are installed; medium- and high-frequency eddy current inspections for cracking of the frames around the attachment holes of the subject brackets; and repair if necessary. The original NPRM would also have required installing new, improved fittings for all support brackets of the A/C outlet extrusions between BS 360 and BS 907. The original NPRM resulted from numerous reports of multiple cracks in the frames around the attachment holes of certain support brackets of the A/C outlet extrusions. This action revises the original NPRM by adding an airplane to the applicability and reducing the compliance time for certain airplanes. We are proposing this supplemental NPRM to prevent frame cracking, which, if not corrected, could lead to a severed frame that, combined with cracking of the skin lap splice above stringer 10, could result in rapid decompression of the airplane.

The FAA is amending type certification standards for aircraft engine control systems. These changes reflect current industry practices and harmonize FAA standards with those recently adopted by the European Aviation Safety Agency (EASA). These changes establish uniform standards for all engine control systems for aircraft engines certificated by both U.S. and European countries and will simplify airworthiness approvals for import and export.

The Federal Aviation Administration (FAA) and the National Park Service (NPS), in accordance with the National Parks Air Tour Management Act of 2000, announce the next meeting of the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). This notification provides the dates, location, and agenda for the meeting. This notification revises Federal Register notice published on July 30, 2008 (Vol. 73, No. 147, Page 44311) to indicate a change in the meeting location and time of meetings. Dates and Location: The NPOAG ARC will meet on September 3-4, 2008. The meeting will now take place in a commercial office building at 826 East Front Street, Port Angeles, WA, leased by the NIPS. The office phone number at this facility is (360)-565-1320. The meetings will be held from 8 a.m. to 5 p.m. on September 3 and from 8 a.m to 3 p.m. on September 4th. This NPOAG meeting will be conducted in closed session and is not open to the public.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 216: Aeronautical Systems Security.

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 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:

The FAA is superseding an existing airworthiness directive (AD), which applies to certain EMBRAER Model EMB-135 airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. That AD currently requires replacing the metallic tubes enclosing the vent and pilot valve wires in the left- and right-hand wing fuel tanks with non-conductive hoses. This new AD adds airplanes to the applicability of the existing AD. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source inside the fuel tank that could ignite fuel vapor and cause a fuel tank explosion and loss of the airplane.
