The longstanding and dedicated Learjet team at West Star Grand Junction has recently completed their fifth 9600 hour/10,000 (Evolved Maintenance Program) structural inspection on the Bombardier Learjet 45 product line.

The Grand Junction Learjet program is an established and respected resource for the venerable Learjet airframe. And with 424 Lear 45 aircraft still in service, the program’s expertise and knowledge are still in high demand.

The Learjet Team at GJT proudly noted that while performing these heavy structural inspections in conjunction with any due phase inspections, the shop has been averaging 67-day turn times. This is no small accomplishment given the large and detailed scope of this heavy structural inspection.

The scope includes a complete interior removal, engine removal, horizontal stabilizer removal, cockpit windshield removal, pressure floorboard removal, fuselage tank removal, aft pressure bulkhead, and delta fin removal as well.

Then, at this point, the aircraft gets jacked and shored to facilitate lowering the wing for access to the wing-attach fitting. After disassembly, the Learjet team begins with extensive visual inspections while the onsite NDT team performs all the required X-rays, Eddy Current, and dye penetrant inspections.

While the aircraft is disassembled, additional routine Phase Inspections and miscellaneous IRN (Inspection Reference Number) inspection tasks are addressed as well as any other work the operators may choose to have done.

Once the inspections and any additional work scopes are completed, the aircraft begins the re-assembly phase. To date, the team has not found any structural discrepancies that would have required OEM engineering support or extensive structural repairs.

West Star Aviation’s Grand Junction Learjet Program is proud to continue to support the Learjet 45 and other variants of the proven and trusted airframe.
