FAA proposes AD that could cost aircraft owners millions

SAN ANTONIO, Texas — The FAA has proposed an Airworthiness Directive (AD) to limit the allowable time-in-service of more than 30,000 TITAN brand 520- and 550-series cylinder assemblies installed on about 6,000 Continental IO-520, TSIO-520, IO-550 and IOF-550 engines. The proposed AD would require that these cylinders be removed from service at 1,000 hours time-in-service. In addition, about half the affected cylinders would be required to be removed from service within 25 hours if their time-in-service is less than 500 hours. Cylinders permitted to continue in service would be subject to repetitive 50-hour inspections until they are retired. The FAA estimates cost of compliance to be $82,620,000.
