Up to 6,000 Continental engines with aftermarket PMA cylinders from Engine Components Internationalcould be affected by a new Airworthiness Directive proposed by the FAA on Monday. The FAA wants to require initial and repetitive inspections, with the replacement of any cracked cylinders. The entire cylinder assemblies would have to be replaced at reduced times-in-service, at a cost of about $1,700. The schedule for inspections and replacement varies depending on the serial number of the parts. The total cost of compliance for the fleet would be about $82.6 million, the FAA said. In a news release issued Monday morning, ECi responded that the FAA's proposal is "unwarranted, inappropriate, and unnecessarily punitive for the owners of the affected aircraft."
