AD: Wytwornia

AD NUMBER: 2003-18-04
MANUFACTURER:
Wytwornia
SUBJECT: Airworthiness Directive 2003-18-04


SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Wytwornia Sprzetu Komunikacyjnego(WSK) PZL -10W turboshaft engines. This AD requires a one-time inspection of the four engine-to-gearbox pin retaining joints for loose or improperly crimped retaining nuts and damaged bolts on certain serial number engines. This AD is prompted by reports of loose or improperly crimped engine-to-gearbox pin joint retaining nuts found during overhaul. We are issuing this AD to prevent loss of nut torque and loosening of engine-to-gearbox pin joint retaining nuts, which could result in misalignment of the engine to the gearbox, causing loss of drive to the gearbox, power turbine overspeed, and uncontained power turbine disc failure.
