Bombardier has extended the intervals between recurring major powerplant inspections for the Learjet 70 and Learjet 75 from 3,000 to 3,500 engine hours.

This interval extension is designed to directly benefit the bottom lines of operators by reducing the number of repeat inspections over the lifecycle of the Honeywell TFE731-40BR engine, thereby decreasing operating costs over the lifecycle of the aircraft. The Learjet family recently surpassed the 25 million flight-hour mark, having first entered the industry in 1964.

“This is a significant milestone for our pace-setting Learjet aircraft family and for the industry," says senior VP of worldwide sales and marketing Peter Likoray. “The Learjet platform is designed to deliver immediate returns as a business productivity tool. Reliability and longevity are two of the reasons customers among Fortune 500 companies continue to choose Learjet as the most trusted light jet platform.”

Both aircraft are certified to Part 25 airworthiness standards, applicable to transport category aircraft and commercial airliners.

Bombardier is continuing to invest to support its in-service fleet and the Learjet family and recently announced a comprehensive Garmin G5000 avionics upgrade, which will allow customers to optimise their routes and will pave the way for future technological enhancements. The upgrade will be offered as forward and retrofit for in-service Learjet aircraft.

Since acquiring the Learjet Corporation in 1990, Bombardier has introduced eight new models, including the LR75, which entered service in 2013.
