Makes named: pacific aerospace. Models named: 750XL. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Pacific Aerospace Limited Model 750XL airplanes, all serial numbers up to and including 215, certificated in any category.

Compliance

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.

Required actions

The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Small Airplane Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Mike Kiesov, Aerospace Engineer, FAA, Small Airplane Standards Branch, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4144; fax: (816) 329-4090; email: mike.kiesov@faa.gov . Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, Small Airplane Standards Branch, FAA; or the Civil Aviation Authority of New Zealand (CAA).

Unsafe condition

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and address 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 prevent the spread of fire into the cabin in case of an engine fire.

Affected ADs

None.
