Bombardier has received regulatory approval from EASA for its Honeywell TFE-731-20BR engine upgrade. The approval means that Bombardier can begin delivering production aircraft to its Learjet 45 XR customers in any of EASA’s 25 member countries. Alongside revisions to the flight manual, Bombardier says it will also issue a service bulletin aimed at current Learjet 45 operators in December, allowing them to upgrade their aircraft at Lufthansa Bombardier Aviation Services in Berlin.
