Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all Dornier-Werke G.m.b.H. (Dornier) Model Do 27 Q-6 airplanes. This proposed AD would require you to inspect the aileron and flap control cables for proper clearance from the fuel lines in the fuselage and make necessary adjustments; and inspect the fuel lines for damage and correct routing. This proposed AD would also require you to replace all damaged fuel lines and reroute incorrectly routed fuel lines. After all other corrective action is taken, this proposed AD would also require you to install protective sleeves on the fuel lines. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this proposed AD are intended to detect and correct damaged fuel lines and prevent the potential for further damage occurring to the fuel lines in the fuselage. Damage to the fuel lines could result in fuel leaking into the fuselage which could cause a fire or explosion.
