The FAA last week proposed to issue a new airworthiness directive (AD) that would affect certain (Cessna) Textron Aviation 172/182/206/207/210 airplanes. A report of cracks found in the lower area of the forward cabin doorpost bulkhead prompted this notice of proposed rulemaking (NPRM). This condition is determined to be the result of metal fatigue. If not addressed, it could lead to failure of the wing in operation, which could result in loss of control.
The AD would require repetitive inspection of this area for cracks and would require owners to make any necessary repairs in accordance with the applicable Cessna service kit. The FAA estimates that this proposed AD affects 14,653 airplanes of U.S. registry. For more details on the inspection and repair requirements of this NPRM, as well as instruction for submitting comments, go here. The comment period closes on March 19, 2018.
