Airworthiness Directive · Amendment 39-15339 · Flight controls
Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko” Model SZD-50-3 “Puchacz” Gliders
Superseded. A later AD replaced this one: AD 2008-09-08. Comply with the one in force.
This AD applies to Model SZD-50-3 “Puchacz” gliders, all serial numbers up to and including B-2207, 503199327, 503A04001, 503A05002, and 503A05003, 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 the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 10 days after February 1, 2008 (the effective date of this AD), inspect the left-hand (LH) and the right-hand (RH) wing airbrake intermediate control levers for loose attaching bolts following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE-059/SZD-50-3/2007 “PUCHACZ,” dated October 15, 2007.
(2) Before further flight after the inspection required in paragraph (f)(1) of this AD if any loose bolt is found, on both wings replace the split helical spring lock washers with tab washers and replace the M8x34 bolts with M8x32 bolts following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE-059/SZD-50-3/2007 “PUCHACZ,” dated October 15, 2007.
(3) No further action is required at this time if no loose bolts were found during the inspection required in paragraph (f)(1) of this AD.
Note: This AD differs from the MCAI and/or service information as follows: (1) The MCAI and the service information require repetitive inspections if no loose bolts are found during the initial required inspection until the next 1,000-hour time-in-service (TIS) overhaul after the effective date of the AD, at which time replacing the split helical spring lock washers with tab washers and replacing the M8x34 bolts with M8x32 bolts is required. (2) This AD is considered an interim action because we are not including a repetitive inspection requirement in this AD. The Administrative Procedure Act does not permit the FAA to “bootstrap” a long-term requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The short-term action and the long-term action are analyzed separately for justification to bypass prior public notice. (3) After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require the inspection to be repetitive and to require a terminating action. Credit will be given in any subsequent action for the initial inspection done under this AD.
