Pacific Aerospace Corporation, Ltd. Model 750XL Airplanes
This AD applies to Model 750XL airplanes, all serial numbers, certificated in any category, that have not incorporated Pacific Aerospace Limited Service Letter PACSL/XL/07-1, dated April 18, 2007, with Pacific Aerospace LTD Drawing, 11-03129, Issue B or subsequent, in its entirety.
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: To prevent the cockpit door windows separating from their frames, * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
Unless already done, do the following actions:
(1) Within the next 50 hours time-in-service (TIS) after October 17, 2007 (the effective date of this AD) and thereafter at intervals not to exceed 50 hours TIS, inspect the windscreen and cockpit door windows for signs of disbonding of the adhesive between the transparency and the composite window frame following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/0276) and PAC Drawing No. 11-03137, both dated February 20, 2007 (undated). If you find disbanding during any inspection required by this AD, before further flight, modify the windscreen and cockpit windows to incorporate mechanical fasteners following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/0276) and PAC Drawing No. 11-03137 both dated February 20, 2007.
(2) Within the next 150 hours TIS after October 17, 2007 (the effective date of this AD) or within the next 6 months after October 17, 2007 (the effective date of this AD), whichever occurs first, modify the windscreen and cockpit windows to incorporate mechanical fasteners following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/0276) and PAC Drawing No. 11-03137 both dated February 20, 2007. The requirement of paragraph (f)(1) of this AD to do repetitive inspections is no longer necessary when the modification of paragraph (f)(2) of this AD is done.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
