Improved cockpit environmental control system muffler for your Learjet 45

Bombardier is pleased to offer an improved cockpit environmental control system (ECS) muffler assembly for the Learjet Model 45 family of aircraft – including Learjet 40, Learjet 45, Learjet 70, and Learjet 75.  

The improved assemblies were designed and tested by Bombardier’s engineering team. The new cockpit ECS muffler delivers a longer service life than the original equipment. Installation takes approximately three days and may be completed at any Bombardier Service Centre or one of our Authorized Service Facilities.

Moving forward, Learjet Bombardier will no longer repair failed muffler units. They are being phased out and replaced with the improved cockpit ECS muffler assembly. 

The new part numbers are listed in the IPC and are available from Parts Services, P/N 12945-096-801 and 4521202352-007.
