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 various Cessna 172, 182, and 206 models.
- This AD addresses persistent fuel line fitting separation, which led to engine failures even after a previous, less specific directive.
- The new AD clarifies that the torque values of fuel line fittings must be physically established, as visual inspections alone proved insufficient.
