Summary
We propose to supersede Airworthiness Directive (AD) 2013-19- 12 for GA 8 Airvan (Pty) Ltd Models GA8 and GA8-TC320 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 the fuel system integral sump tank does not meet FAA regulations. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
