Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Model SR20 and SR22 airplanes. This proposed AD would require you to inspect the fuel line and wire bundles for any chafing damage; if any chafing damage is found, replace any damaged fuel line and repair any damaged wires or sheathing of the wire harness; and install the forward loop clamp, fuel line shield, aft loop clamp, and anti-chafe tubing. This proposed AD results from reports of fuel line leaks resulting from wire chafing on the fuel lines. We are issuing this proposed AD to detect and correct damage to the fuel line and wire bundles, which could result in fuel leaks. This failure could lead to unsafe fuel vapor within the cockpit and possible fire.
