The FAA has enacted an Airworthiness Directive (AD) concerning the tightness of fuel line fittings on various Cessna 172, 182 and 206 models after the same problem kept cropping up after the first AD was issued last August. The original AD was intended to ensure that the fittings were all tightened properly to prevent them from separating from various fuel system components. However, the FAA now says it wasnt specific enough in the first AD and there have been at least four engine failures due to fuel line separation since it was issued. [more] The original AD didnt specify that the torque settings of the fittings be checked and some aircraft got only visual inspections. This AD clarifies that the torque values need to be physically established and visual inspection only is not sufficient, the AD reads. It comes into effect on May 2 but why not beat the rush.
Cessna Fuel Line AD Clarified
Key Takeaways:
- The FAA has issued a new Airworthiness Directive (AD) for Cessna 172, 182, and 206 models concerning loose fuel line fittings.
- This AD replaces a previous, insufficient directive, as four engine failures due to fuel line separation have occurred since its issuance.
- The updated AD clarifies that physical torque setting verification of fuel line fittings is mandatory, deeming visual inspections alone insufficient.
