NTSB: Action needed on ECi cylinders

The National Transportation Safety Board is recommending that the FAA require repetitive inspection of some cylinder assemblies on Teledyne Continental Motors Model 520 and 540 engines not covered by existing airworthiness directives issued following engine failures, according to a report at AOPA.org.

The report quotes the Feb. 24 safety recommendation, noting the NTSB said it wants the FAA to “require repetitive inspection of Engine Components, Inc. cylinder assemblies produced between May 2003 and October 2009 (serial numbers 7709 through 52884) installed on Teledyne Continental Motors model 520 and 550 engines and removal of these cylinder assemblies once they reach the engine manufacturer’s recommended normal time (hours) in service between overhauls.”
