Bombardier has sold five Learjet 75 aircraft to an undisclosed customer in a $69m transaction.

Earlier this year, Bombardier’s fleet of Learjet aircraft surpassed the 25 million flight-hour mark.

The first Learjet business aircraft became operational in 1964. Entering service in 2013, Learjet 75 features private cabin, an eight-seat double club configuration, and a pocket door for reduced noise levels.

The aircraft is the only business jet in the light jet category to feature a flat floor throughout the cabin.

“Reliability and longevity are just two of the reasons customers among Fortune 500 companies continue to choose Learjet aircraft for productivity gains.”

Bombardier Business Aircraft Worldwide Sales and Marketing senior vice-president Peter Likoray said: “The ultimate business tools, Learjet 75 aircraft feature industry-leading performance and help drive direct bottom line results.

“Reliability and longevity are just two of the reasons customers among Fortune 500 companies continue to choose Learjet aircraft for productivity gains. With its bevvy of recent enhancements, the Learjet 75 aircraft is a superior business jet offering in terms of size, performance and reliability, all at highly competitive operating cost.”

Bombardier recently released a comprehensive Garmin G5000 avionics upgrade for the light business jet.

The upgrade is intended to allow customers to optimise their routes and facilitates future technological enhancements.

Bombardier noted it will provide the upgrade as forward and retrofit for in-service Learjet aircraft.

Furthermore, Learjet 75 aircraft operators will benefit from lengthened intervals between recurring major power plant inspections. The company extended these intervals from 3,000 to 3,500 engine hours.

Bombardier purchased Learjet Corporation in 1990. The firm has so far introduced eight new models.

Earlier this month, the Canadian company announced that it will pursue the sale of its Belfast and Morocco aerostructures businesses in order to optimise its global manufacturing footprint.

In addition, Bombardier will consolidate its aerospace assets into a single, integrated business unit, known as Bombardier Aviation.
