 AD/AE 3007/2 (continued)

            This Airworthiness Directive becomes effective on 2 September 2004.

            Background: The Allison Engine Company notified the United States Federal Aviation Administration (FAA) that there was a quality problem with FADECs that have certain hardware SN's installed on AE 3007 series engines. This could lead to an uncommanded engine shutdown in flight, the inability of the FADECs to switch from one channel to another channel (channel A to B) or the inability to shutdown an engine. Three uncommanded in-flight engine shutdowns, eight events in which the FADEC channels could not be changed and three events in which the engine
