Plain English Summary

2/10 complexity

This airworthiness directive requires operators of AlliedSignal TPE331-1, -2, -3U, -5, -6 and -14 engines to inspect fuel manifold assemblies for internal cracking or leaks and to immediately replace any defective assemblies with manufacturer-approved parts. It responds to a supplier manufacturing defect that can cause fuel leaks and engine fires. Compliance is mandatory within 50 flight hours of 12 April 1996 or before 1 July 1996; the amendment adds a second approved service bulletin as an alternative replacement method.

Requirement: Check and replace, if necessary, the fuel manifold assembly in accordance with AlliedSignal Aerospace Alert Service Bulletin TPE331-A73-7023 or TPE331-A73- 0242 as applicable.

Compliance: Within 50 hours time in service (TIS) from 12 April 1996 or before 1 July 1996 whichever occurs first.

Background: AlliedSignal has advised that internal cracks in the fuel manifold hose assemblies, caused by a defective manufacturing process by one vendor, have developed leaks.

The action mandated in this AD is to remove the suspect fuel manifold assemblies and install serviceable parts in accordance with the manufacturer's requirements.

This amendment extends the range of applicability by including reference to another manufacturer's service bulletin on the same subject.
