An Overhaul Process Built on Experience Penn Yan Aero’s overhaul process is backed by more than 80 years of experience and thousands of Lycoming and Continental engines rebuilt for aircraft operating worldwide. Our FAA-approved proprietary techniques produce smoother-running, longer-lasting engines. When manufacturers collaborate with Penn Yan Aero on product improvements, it’s a clear measure of the trust we’ve earned — and why our overhauls are among the most respected in the industry.
Penn Yan Aero guarantees that each overhauled Lycoming and Continental certified piston aircraft engine will be free from defects in materials and workmanship for a duration of three (3) years or until the Original Equipment Manufacturer’s (OEM) Time Between Overhaul (TBO) applicable at the time of overhaul by Penn Yan Aero expires, whichever comes first.
