GA 8 Airvan (Pty) Ltd Airplanes
Superseded. A later AD replaced this one: AD 2015-06-02 R1. Comply with the one in force.
This AD applies to GA8 Airvan (Pty) Ltd GA8-TC320 airplanes, all serial numbers affected, certificated in any category.
We are adopting a new airworthiness directive (AD) for GA 8 Airvan (Pty) Ltd Model GA8-TC320 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 missing required engine mount fire seal washers, which could reduce the engine retention capability in the event of a fire. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, comply with this AD within the compliance times specified in paragraphs (f)(1) through (f)(4) of this AD:
(1) Within the next 300 hours time-in-service after April 24, 2015 (the effective date of this AD) or within the next 12 months after April 24, 2015 (the effective date of this AD), whichever occurs first, inspect the orientation of the engine isolator mounts to verify that the mounts have been installed properly following the Accomplishment Instructions in GippsAero Mandatory Service Bulletin SB-GA8-2014-115, Issue 1, dated October 6, 2014.
(2) Before reinstalling the engine isolator mounts following the inspection required in paragraph (f)(1) of this AD, before further flight, install a part number J-2218-61 steel washer on the forward side of each of the four engine isolator mounts, following the Accomplishment Instructions in GippsAero Mandatory Service Bulletin SB-GA8-2014-115, Issue 1, dated October 6, 2014.
(3) If during the inspection required in paragraph (f)(1) of this AD, any of the engine isolator mounts are found to not comply with the specifications found in the Accomplishment Instructions of GippsAero Mandatory Service Bulletin SB-GA8-2014-115, Issue 1, dated October 6, 2014, before further flight, re-install the isolators to the correct orientation, or if damage is found, replace with airworthy parts.
