An airworthiness directive that requires repetitive inspection of an estimated 14,653 single-engine Cessna airplanes for cracking of the strut attach fittings at the forward cabin doorposts will take effect November 12.
The FAA modified some provisions of the AD in June 2020 and accepted additional public comments until mid-July.
The inspection and reporting costs have been estimated at $212.50 per aircraft, with the cost of any needed repairs contingent on the inspection results, and the repairs to be conducted based on the applicable service kits, the AD said.
