Airworthiness Directives; PZL Swidnik S.A. Helicopters

FAA / Federal Register · 2020-16120

The FAA is adopting a new airworthiness directive (AD) for certain PZL Swidnik S.A. (PZL) Model W-3A helicopters. This AD requires repetitive inspections of the main transmission (Main XSMN) case for a crack, and depending on the inspection outcome, removing the WR-3 Main XSMN from service before further flight. This AD was prompted by a report of cracks in a Main XSMN case. The actions of this AD are intended to address an unsafe condition on these products.
