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 regarding fuel line fitting tightness.
- This AD was necessitated by recurring fuel line separations and at least four engine failures, indicating a previous AD was not specific enough.
- The clarified AD mandates physically establishing the torque values of fuel line fittings, stating that visual inspection alone is insufficient.
