Federal Aviation Administration June 12, 2007 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 Airplanes. This proposed AD would require you to inspect the starter-generator to determine the serial number (S/N) and suffix letter, which indicates if the part is defective, and replace any defective starter-generator with one of new design. This proposed AD results from reports of a manufacturing error where certain starter-generators may have been improperly shimmed. We are proposing this AD to detect and replace defective starter-generators, which could result in premature starter- generator failure. This failure could lead to increased chances of dual starter-generator failure on the same flight.

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.
