  • Fleet Focus: Boeing 737NG aircraft

WestJet Airlines is one of Canada's leading carriers, known for its commitment to operational excellence and fleet reliability. In 2010, WestJet was preparing for an increase in maintenance demands and needed a specialized solution for main landing gear (MLG) removal and inspection tasks on its Boeing 737NG fleet.

Challenge

In light of Airworthiness Directive 2009-26-04, WestJet was required to perform inspections on the forward trunnion pins of their Boeing 737NGs. Additionally, the airline was preparing to launch a full-scale Landing Gear Overhaul Program beginning in 2011.

These dual factors required a dependable and efficient tooling solution that would:

  • Facilitate MLG removal and installation.

  • Meet regulatory inspection requirements.

  • Support future maintenance operations with flexibility and ease.
