RE:Bombardier stresses continued Learjet supportAmazing article, proving the dedication and effectiveness of BBD. Learjet its a ''2,000 aircraft still in service remains robust, and accounts for a significant portion of its $2 billion in annual product support revenues.'' Learjet customers continue to be supported by nine Bombardier-owned service facilities. Bombardier has added more than one million square feet of maintenance facilities. Regier said business has seen a strong uptick over the last two years, with more customers upgrading their aircraft. “There’s been a huge rise in revamping and refinishing, reinventing the aircraft.” While Bombardier still offers full engineering and technical support for its 20, 30, and 50 series Learjet aircraft, it has partnered with VSE Aviation for parts supply for those models. Other parts are available from salvage firms in Oklahoma and Kansas.Cox admitted that the lead time for older aircraft parts “is becoming more difficult. We have to look for rare parts, but we maintain the drawings, tooling, and capability to be able to produce those parts.” Parts for 20 and 30 series can be ordered directly from approved partners. Cox said Bombardier works with supplier partners “on their forecasting models to make sure they’ve got adequate stock.” And customers enrolled in Smart Services can still order directly from Bombardier.
