Airworthiness Directive · Amendment 39-19340 · Nacelles/pylons
Pacific Aerospace Limited Airplanes
This AD applies to Pacific Aerospace Limited Model 750XL airplanes, all serial numbers up to and including 215, certificated in any category.
We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. 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 airplane sound insulation materials attached to the aft face of the firewall not complying with the applicable burn testing criteria for materials on the cabin side of the firewall. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD:
(1) Within 90 days after August 31, 2018 (the effective date of this AD), inspect the aft face of the firewall and determine if the sound insulation material is installed per the Inspection Instructions in Pacific Aerospace Service Bulletin PACSB/XL/095, Issue 1, dated December 21, 2017.
(2) If a layer of black foam insulating material is found covering the firewall during the inspection required in paragraph (f)(1) of this AD, before further flight, remove the material per the Accomplishment Instructions in Pacific Aerospace Service Bulletin PACSB/XL/095, Issue 1, dated December 21, 2017.
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.
