Commissioned by the U.S. Army Corps of Engineers, this facility was constructed to house a state-of-the-art aircraft maintenance hangar capable of servicing up to six military helicopters simultaneously. Maintaining up to six helicopters simultaneously means aircraft roll in and out on their own schedules – for fueling, repairs, or rapid-response missions. Traditional wide-span doors force crews to open every panel, exposing the entire hangar to wind, rain, salt spray, and dust each time a single aircraft moves.
Engineering challenge Providing flexible simultaneous access to six helicopters in a high-frequency situation and meeting the US Department of Defense Unified Facility Criteria (UFC) and Hawaii Building Code (HBC) wind-load codes for >145 mph, in a location with corrosive sea air and high wind potential.
Custom solution Flexible access was provided by Independent Blade Control, where each door door is motorized and can be opened, closed, or positioned individually from a pair of remote pendants on either side of the door. This approach delivers several operationally related advantages:
Ground crews open only the bay they need, letting one helicopter depart while the others stay protected.
Reduced Air Exchange – Minimizes energy loss, maintains interior climate control, and cuts down on foreign-object debris (FOD) blowing into sensitive maintenance areas.
Faster Turnarounds – No waiting for a full door cycle; aircraft can taxi in or out within seconds of clearance.
High-strength, corrosion-resistant steel and sealed bearings for long life in salt-laden air.
Redundant safeties and manual overrides ensure operation during power or control-system interruptions.
