Federal Aviation Administration July 29, 2008 – Federal Register Recent Federal Regulation Documents

This document makes a correction to a proposed airworthiness directive (AD), which was published in the Federal Register on July 3, 2008 (73 FR 38160), and applies to certain Stemme GmbH & Co. KG (Stemme) Model S10-VT powered sailplanes. This document proposed to require replacement of the single ear clamps in the fuel system with improved design parts. The FAA incorrectly referenced the docket number of this proposed AD as ``FAA-2008-0685'' instead of ``FAA-2008-0788.'' This document corrects the docket number.

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 175 and 175A airplanes. This AD requires you to check the airplane logbook to determine if the original engine mounting brackets have been replaced. If the original engine mounting brackets are still installed, this AD requires you to repetitively inspect those brackets for cracks and replace any cracked engine mounting bracket. After replacing all four original engine mounting brackets, no further action will be required by this AD. This AD was prompted by a report that the engine became detached from the firewall during landing on one of the affected airplanes. We are issuing this AD to detect and correct cracks in the engine mounting brackets, which could result in failure of the engine mounting bracket. This failure could lead to the engine detaching from the firewall.
