August 18, 2025

Owners and operators of the more than 300 Challenger 604s manufactured by Bombardier can now enroll their General Electric CF34-3B engines and APUs with Engine Assurance Program's hourly engine maintenance programme. The business jet is popular for its 4,000-mile range, spacious interior and powerful engines. Those engines are the most recent addition to EAP's ever-expanding offering. EAP also covers the General Electric CF34-3A/-3A1/-3A2, which powers the Challenger 601 1A/3A/3R aircraft.

“The robust performance of the CF-34-3B engine shows its roots in military service. We're excited that this high-performing engine now has access to EAP's high-performing support,” says Sean Lynch, EAP managing director. “With EAP, you only need one resource to help with all your engine coverage needs versus dealing with multiple different OEM programmes. That saves customers time and effort.”

EAP continues to expand the list of engines covered by its hourly maintenance programme. EAP already covers all variants of the Honeywell TFE731 and recently has focused on adding General Electric, Pratt & Whitney Canada and Rolls-Royce engines to its programme.

“Clients are delighted with EAP's responsive service, robust rental engine pool and significant spare parts inventory, and our growth is evidence of that,” adds Sean.

By owning the spare parts inventory and rental engines/APUs, EAP is able to overcome supply chain issues plaguing the industry and provide proactive customer service and enhanced dispatch reliability. EAP customers have a 99.98 percent dispatch reliability rate. With the recent addition of the new engines, EAP covers a large portfolio of engine models that power many popular business jets from every major manufacturer.
