This AD applies to Model SZD-50-3 “Puchacz” Gliders, all serial numbers, certificated in any category. Reason (d) The mandatory continuing airworthiness information (MCAI) states: Some cases of turnbuckle adjusting screws fatigue failure have occurred, due to lateral load component applied by pilot's foot. Such events may lead to rudder and pedals disconnection.

Unless already done, within the next 3 calendar months after April 19, 2007 (the effective date of this AD), install the extra pull rod between the rear pedals and turnbuckle adjusting screws following Allstar PZL Glider Sp. Z o.o. Mandatory Service Bulletin No. BE-057/SZD-50-3/2006 “PUCHACZ”, dated October 16, 2006, except as specified in paragraphs (e)(1) through (e)(4) of this AD.
