FAA revises emergency AD for Cessna 402C, 414A wing spars
The FAA on Wednesday, March 2, revised the emergency airworthiness directive for Cessna 402C and 414A airplanes. The new AD ( 2005-05-52) effectively increases the time between required wing spar inspections from as little as 15 hours to 110 hours.
The AD replaces the visual inspection of the forward wing spars with an eddy current inspection and continued visual inspection of the aft and auxiliary wing spars. That first AD was considered an interim measure to discover any existing large cracks in the Cessna twins' wing spars.
The new AD exempts aircraft that have a spar strap modification following Cessna Service Bulletin MEB02-5, dated June 24, 2002, and Cessna Service Kit SK402-47, dated June 24, 2002. AOPA is continuing to work closely with the FAA and Cessna owner groups to address fatigue cracking in wing spars on Cessna 400-series aircraft.
