Alaska Airlines maintenance facility at Seattle-Tacoma International Airport includes a hangar, avionics and electrical shops, parts storage, a separate building for ground-support equipment, and a 100,000 SF apron that can accommodate five parked aircraft.

With a clear span of 288 feet at the door and a clear height of 60 feet, the 90,000 SF hangar can simultaneously service any combination of the three types of aircraft in Alaska Airlines’ current fleet.  It also has the capability to accommodate future wide-body aircraft.

Telescoping overhead work platforms suspended from the roof trusses provide access to aircraft in any part of the hangar.  An overhead fire-protection system can deluge jet-fuel fires with a mixture of chemical foam and water.
