Another Engine Concern
The FAA has issued an Airworthiness Directive (AD) that requires the replacement of certain ECi "Classic Cast" cylinder assemblies installed on Lycoming 320-, 360-, and 540-series parallel valve engines. The cylinders are found in more than 1,500 engines in the U.S., and must be replaced within 800 hours of time in service. Replacing all four cylinders on a typical Lycoming 360 would take about 12 hours and cost about $4,900, the FAA estimates. Ed Salmeron, president of ECi, told AVweb yesterday the AD reflects the intent of a Mandatory Service Bulletin issued by ECi last September. "ECi has instituted a pro-rated replacement program for parts and labor to be used when the affected cylinders come up for replacement," he said. Cylinders that have more than 800 hours in service may remain in service for an additional 60 hours before replacement is required, Salmeron said. The AD was proposed in September, and since the FAA received only two comments, it has now finalized the rule, effective Jan. 31.
