The FAA has published a controversial airworthiness directive requiring the removal of Engine Components International (ECi) cylinders in some 6,200 Continental engines. The average cost to comply with AD, the FAA says, will be $11,520 per engine. The AD goes into effect on September 15.
The FAA cited a total of 82 ECi cylinder failures during the 11 years they’ve been in use. This includes two fatal accidents that were attributed to those failures. The AD affects Continental -520 and -550 engines with ECi cylinders, as well as engine models approved for the use of the cylinder assemblies by supplemental type certificate, such as the the model -470.
Some pretty tight time restrictions in the article that will mean most engines will not make it anywhere close to overhaul without cylinder replacements.
