Full official abstract

We are superseding an existing airworthiness directive (AD) for Thielert Aircraft Engines GmbH (TAE) Models TAE 125-01 and TAE 125- 02-99 reciprocating engines. That AD currently requires replacement of certain part numbers (P/Ns) and serial numbers (S/Ns) of clutch assemblies due to clutch failure. The failures identified above could lead to engine in-flight shutdown and loss of control of the airplane. This AD requires the same actions, but applies the corrective action to an additional 244 affected clutch assemblies. This AD was prompted by TAE identifying additional clutch assemblies with nonconforming disc springs. We are issuing this AD to correct the unsafe condition on these products.
