Airworthiness Directives; Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko” Model SZD-50-3 “Puchacz” Gliders
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.
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Airbus Model A310 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus airplanes, listed above. This proposed AD would require installing two-stage relays in the electronics rack (90VU), and performing related corrective and investigative actions. This proposed AD is prompted by reports of in advertent rudder trim activation when the autopilot is on. We are proposing this AD to prevent inadvertent trim activation when the autopilot is on and the slats are extended, which could result in rudder activation when the autopilot is turned off.
