AD 2006-24-09 Airworthiness Directives; PZL-Bielsko Model SZD-50-3 “Puchacz” Gliders

This AD applies to PZL-Bielsko Model SZD-50-3 “Puchacz” gliders, all serial numbers, certificated in any category. Reason (d) The mandatory continuing airworthiness information (MCAI) states that the aircraft manufacturer has identified a discrepancy between the design documentation and the Technical Service Manual. In 1981, a castellated nut with cotter pin was introduced to secure the rudder, replacing the self-locking nut, through PZL Bielsko Bulletin No. BE-06/50-3/81. This change has not been introduced to the Technical Service Manual and use of a self-locking nut, in accordance with the Manual, is still possible. This was probably the reason for rudder disconnection during flight which occurred recently. If not corrected, loss of the nut could result and allow the rudder to slip out of its hinges, separate from the glider, and lead to loss of control.

Unless already done, do the following actions except as stated in paragraph (f) below: Within 30 days of January 3, 2007 (the effective date of this AD) or before further flight, whichever occurs later, inspect and, if necessary, replace the Rudder Attachment parts in accordance with the instruction contained in Allstar PZL Glider Sp. z o.o. Mandatory Bulletin No. BE-058/SZD-50-3/2006 “PUCHACZ”, dated August 10, 2006. Concurrently, changes in the Technical Service Manual must be introduced in accordance with the referenced Bulletin.
