Samenvatting
We propose to rescind an airworthiness directive (AD) for the products listed above. The existing AD, AD 98-09-27, resulted from aircraft certification testing which revealed that stresses on the thrust reverser hinge were higher than had been anticipated during engine certification, and the United Kingdom Civil Aviation Authority, issuing AD 008-03-97. Since we issued AD 98-09-27, we discovered that its requirements were duplicated in airplane-level AD 2001-09-14, issued by the FAA Transport Airplane Directorate. This proposal to rescind the engine- level AD allows the public the opportunity to comment on the FAA's determination of the duplication of requirements in another AD, before we rescind the engine-level AD.
