John Jewell Aircraft / STC Services / C182 John Jewell Aircraft / STC Services / C182 Home > STC Services > C182 STC Services - C182 C210 FAA Supplemental Type Certificates (STC) Better than new plane performance, at less than a new plane price. STC's have always been a popular means to upgrade an aircraft to higher performance levels, as well as increasing aircraft value without purchasing an entirely new aircraft. The average age of the approximately 250,000 single and light twin-engine aircraft around the world is thirty years. These conversions allow aircraft owners to upgrade their existing engine and propeller, adding value, performance, and efficiency to their aircraft. John Jewell Aircraft, Inc. located in Holly Springs, Mississippi is proud to offer engine and prop performance upgrades for the Cessna 182 H-R series aircraft. JJA is pleased to provide these STC options with their existing product lines.

Customer Reviews Carbureted 252 http://www.johnjewellaircraft.com/services/stc/c182/index.html[3/31/2015 3:14:29 PM] John Jewell Aircraft / STC Services / C182 I'm very pleased with the conversion. The takeoff and climb performance have been greatly improved, bordering on phenomenal. It just wants to jumpoff the ground. There is some improvement in cruise performance but Ihaven't had it long enough to evaluate totally. It seems I can get the same speed with a slightly lower power setting which gives a lower fuel burn. The conversion is basically invisible with the exception of the new tachometer. William Binford Anderson, SC Fuel Injected 300 My partner and I feel that the Bonaire stc conversion kit to I0-550 on Cessna 182 is excellent. It's a performer airplane on wheel and float.
