Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa "PZL- Bielsko" Model SZD-50-3 "Puchacz" gliders. This proposed AD would require you to perform a visual inspection of the turnbuckle link for cracks or wear and replace if cracks or wear is found. This proposed action would only apply to those gliders where the turnbuckle is directly connected to the pedal. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Poland. We are issuing this proposed AD to detect and correct cracks in the turnbuckle link, which could result in failure of the rudder cable. This failure could lead to loss of control of the glider.
