Abstract: The aircraft wash rack has a supporting frame being attached to the hangar ceiling and a safety track being specifically constructed for the particular aircraft shape is attached to the supporting frame. In order to construct the safety track, the aircraft is placed in the position where the cleaning occurs. A story pole is moved about the aircraft outer surface edges to measure the height of the track above the aircraft as well as to determine the position of the track on the aircraft upper surface. The track usually is about 2 feet or so from the wing edges. After this information is determined, the safety track is constructed and attached to the supporting frame. A roller guide is attached to the track with a rope therefrom which is further attached to a rope adjuster. This is attached to the maintenance person who would be wearing a harness.
