Airworthiness Directives; Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko” Model SZD-50-3 “Puchacz” Sailplanes

Zusammenfassung

The FAA adopts a new airworthiness directive (AD) for all Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa "PZL-Bielsko" (PZL-Bielsko) Model SZD-50-3 "Puchacz" sailplanes. This AD requires you to repetitively inspect the front and back of the fuselage front bulkhead attachment fitting for cracks and replace the attachment fitting if any cracks are found. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Poland. We are issuing this AD to detect and correct cracks in the fuselage front bulkhead attachment fitting, which could result in structural failure of the bulkhead. This failure could lead to loss of control of the sailplane.
