Airworthiness Directive · Amendment 39-14838 · PZL-Bielsko Model SZD-50-3 “Puchacz” Gliders
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.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as 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. We are issuing this AD to require actions that are intended to address the unsafe condition described in the MCAI.
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.
None.
