The Penn Yan Aero overhaul process is the
result of over 70 years of experience overhauling
thousands of Lycoming and thousands of
Continental engines installed in all kinds of
airframes flying in all kinds of environments
around the world.
The Penn Yan Aero proprietary overhaul process
is FAA Approved and incorporates dozens of unique
techniques that result in a smoother-running,
longer-lasting engine that helps make flying
safer and lowers operational costs. Fleet
