The US Aircraft Owners and Pilots Association (AOPA) has called on the US Federal Aviation Administration to reconsider its airworthiness directive (AD) on turbocharged twin-engined Cessnas, claiming that the requirements are too costly, too complex and not necessary. "While the FAA estimates that the inspection mandated by the AD would cost the owner $4,340, many would have to replace the exhaust system components, costing up to $200,000 per aircraft," says AOPA. It has asked the FAA to accept a AD proposal by the Cessna Pilots Association which requires "regular inspection and replacement routines".
