Aircraft Fuselage Apertures - Special Application Doors

Most commonly used in military hangars are slide doors of the anchored and floating group, and individually motor-operated types. However, the exacting requirements for the ever increasing number of different aircraft dictate the use of aperture doors. Fleming has designed many types of aperture doors - some with stationary panels, others are vertically, horizontally, and diagonally adjustable independent of the host door leaf, either manually or by motor. Aperture panels can easily be changed if new aircraft are assigned to the hangar.

US Airways' Hangar No. 4 at Pittsburgh International Airport was built to maintain aircraft in the mid 1960's. Recently, its mission was expanded to service Boeing 757 and 767 aircraft. Unfortunately, the depth of the hangar was not sufficient to receive the larger aircraft.

Fleming removed one of the existing door leaves and replaced it with two new individually motor-operated sliding door leaves, each measuring 29'-0" wide by 36'-4.5" high. Installed on the new slide door leaves are fully motorized Boeing 757 & 767 fuselage aperature door systems and an exterior closure door system. The entire door system is controlled from either exterior and / or interior control stations. The aperature doors move vertically independent of the slide doors.

Pictured above is an interior view of the doors with the closure door system closed. The B-757 fuselage aperature doors (on independent slides) are fully retracted to their stored position; leaving the B-767 fuselage aperature door system unobstructed in the center. The yellow weather-sealing cushions on each fuselage aperature door are pneumatic safety edges that prevent crushing the fuselage when engaging the doors around the aircraft.
