Eclipse jets can cruise at 41,000 feet again

摘要

A problem with carbon buildup in the Pratt & Whitney PW610F engines used by Eclipse jets has been solved, allowing them to return to 41,000 feet. The approval is effective immediately for owners and pilots installing recertified combustion liners in their engines. The problem was seen in a small number of aircraft in recent years, but was serious enough for the FAA to limit operations to 37,000 feet.
