Engine Overhaul Product Strategy

Oscoda Engine Services Engine Services will continue to dominate its position in the “niche” JT8D support market. The JT8D engine was first built in 1963 and became the world’s most popular jet engine, with over 14,000 of all variants produced. There are still many of these engines in operation, and a relative few engine MRO providers have chosen to continue to invest in servicing this segment of the market. With a facility and dedicated test cell capable of servicing all variants of the JT8D, Oscoda Engine Services Engine Services uniquely provides its customers priority and focus not found elsewhere.
