Keeping a fleet of passenger aircraft in service is no easy feat. For Calgary-based WestJet, that means hangars, technical crews, spare engines, and a growing network of suppliers close to its home base. WestJet chief executive Alexis von Hoensbroech recently gave the Financial Post an exclusive behind-the-scenes look at the airline's maintenance hub at YYC Calgary International Airport, revealing a side that passengers rarely see.
Day and Night Operations
Von Hoensbroech explained that WestJet's Boeing 737s and Dash 8-400 aircraft typically fly during the day and undergo maintenance at night. In contrast, wide-body aircraft like the Boeing 787 Dreamliners often operate overnight and spend time in the hangar during the day. This careful scheduling ensures that the fleet remains operational and safe.
The Role of Alberta's Aviation Ecosystem
The CEO credited the province of Alberta for supporting the airline's maintenance ecosystem by attracting aviation suppliers to Calgary. A prime example is the Lufthansa Technik engine facility, which allows WestJet to avoid the time and cost of shipping an engine to Europe or Asia for maintenance. Instead, the work can be done nearby, saving both time and money.
The High Cost of Spare Engines
Modern aircraft engines are incredibly expensive. Von Hoensbroech noted that a single spare GEnx engine used on a Boeing 787 has a list price of about US$30 million. While this is a huge expense, it is critical for keeping planes flying on time when maintenance calls. The investment in spare engines and local maintenance facilities helps WestJet maintain its schedule and reliability.
The exclusive tour highlighted the complexity and dedication required to keep a fleet of planes flying. From overnight maintenance shifts to strategic supplier partnerships, WestJet's Calgary hub is a vital part of its operations.
