## Summary

We propose to adopt a new airworthiness directive (AD) for certain Technify Motors GmbH TAE 125-02 reciprocating engines. This proposed AD was prompted by a loss of engine power in flight caused by oil leaking from the gearbox radial shaft sealing ring that contaminated the clutch. This proposed AD would require replacement of the clutch with a dual mass flywheel. We are proposing this AD to correct the unsafe condition on these products.
