## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to Pratt & Whitney Canada (PWC) PW100 series turboprop engines, that requires removal of the existing fuel manifold tubes, lock plates, and preformed packing; installation of improved fuel manifold transfer tubes, improved lock plates, and improved preformed packing; and, after installation, the performance of a leak check. This amendment is prompted by reports of engine fuel leaks which resulted in either inflight engine shutdowns or fire warnings. The actions specified by this AD are intended to prevent engine fuel leaks, which can result in inflight engine shutdowns or fire warnings.
