On March 9, George Myles, Jr., owner of Miles Aviation, Inc., was sentenced in Miami to 78 months imprisonment for making fraudulent representations concerning the condition of aircraft parts. Myles was convicted by a federal jury in November. Between 2005 and 2006, Myles purchased used aircraft parts and resold them to the Department of Defense as "new" or "new surplus." The engine parts Myles falsely certified on Defense Department forms were flight-critical; their failure could be potentially catastrophic and/or cause serious damage to aircraft.

Aircraft: AD 2007-05-13 A319/A320/A321
Effect: ...to prevent failure of the attachment points of the YZ-latches, which
could result in unrestrained cargo causing damage to the fire protection system,
hydraulic system, electrical wiring, or other equipment located in the forward
and aft cargo compartments?.. results from tests that have shown that the
attachment points of the YZ-latches of the cargo loading system fail under
maximum loads.  Final rule eff 12 Apr

Aircraft: AD 2007-05-17 JT9D series turbofans
Effect: Requires enhanced inspection of selected critical life-limited parts of
