It was back in 1989 when newly established Jet Support Services, Inc. (JSSI) rolled out its first engine maintenance program for the Honeywell (formerly Garrett) TFE731. Now, as the company celebrates its 25th anniversary, its very first client to enroll in the program is still onboard. Wood product manufacturer Boise Cascade Corporation still owns the very same Dassault Falcon 50, and its three original engines have been tended by JSSI for the past quarter-century.
