AD NUMBER: 2004-21-02
MANUFACTURER: PZL Bielsko SUBJECT: Airworthiness Directive 2004-21-02 SUMMARY: The FAA adopts a new airworthiness
directive (AD) for all Przedsiebiorstwo Doswiadczalno-Produkcyjne
Szybownictwa "PZLBielsko" (PZL-Bielsko) Model SZD-50-3 "Puchacz"
sailplanes.This AD requires you to repetitively inspect the front
and back of the fuselage front bulk head 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.
