We Are the Engine Overhaul Experts!

Since 1961, G&N Aircraft has produced over 20,000 engines. Our staff has over 800 years of combined experience in general aviation.

G&N is a FAA certified repair station (MW2R020L) specializing in the overhaul and repair of engines and engine accessories. We have the in-house capabilities to overhaul most engine components that normally put other shops at the mercy of outside vendors, allowing us to tightly control our quality. Our convenient location is just 20 miles south of Chicago at the Griffith-Merrillville Airport (05C), in Griffith, Indiana, and we are easily accessible by air and highway.

To assure you the finest engine overhaul available, we use genuine Lycoming and  Continental Motors Inc. parts. As a minimum, G&N follows the manufacturers published list of mandatory replacement parts that are required to be replaced at overhaul. Any additional parts that do not meet manufacturers new fits and tolerances are discarded and not used in any engine G&N builds. We have found that new cylinders have become an important consideration for many at overhaul. Customers are considering this in order to minimize future down times.
