Prompted by reports of cracked wing spar caps on several Cessna 210s, the FAA issued an emergency Airworthiness Directive (AD) on Monday, May 21, that requires select Cessna 210 models to be inspected and the results of those inspections be reported back to the FAA. The AD goes into effect on June 5, 2012, and affects 3,665 airplanes of U.S. registry.

If cracks are found during the inspection, further flight is prohibited until the cracked part (spar cap, wing spar, or wing, as applicable) is replaced with a serviceable part, or until an FAA-approved modification is incorporated. This condition, if not corrected, could result in structural failure of the wing with consequent loss of control.
