- 7 - 1.10 Aerodrome and Ground Facilities

Runway 36 at Whiteman AFB is 12,400 feet long and 200 feet wide. It is constructed of concrete and has a 1,000-foot overrun strip at each end. The elevation is 835.91 feet at the landing end and 869.21 feet at the opposite end. The type "A" approach lights and high intensity runway lights were on, at an unknown intensity. At the time of the accident the strobe lights were off. The USAF instrument approach profile chart depicts the field elevation as 869 feet.

Air Traffic services at Whiteman AFB are provided by FAA-certificated, military controller personnel. The control tower is a VFR tower with controller's authority limited to the control of VFR traffic only.

1.12 Wreckage

N6579C crashed approximately 4,200 feet south of runway 36, at Whiteman AFB. The total wreckage was confined to an area approximately 1,200 feet long and 200 feet wide. The fuselage and left wing inboard of the No. 2 engine were extensively damaged by fire.

The first impact markings were found in the top of a tree 48 feet above the ground, 740 feet east of the extended runway centerline, and 4,204 feet south of the threshold of runway 36. Ground elevation at the base of the tree is 848 feet. Initial ground impact was 377 feet from the tree at an elevation 854 feet (m.s.l.) on a magnetic heading of 020 degrees. Sections of the right wing, right flap, right aileron, No. 4 engine, right main landing gear, and the nose gear separated from the aircraft and were found along the skid path left by the aircraft from the point of first ground contact to the final stopping point. The distance from the point of first ground contact to the main wreckage was 1,200 feet and the fuselage was in an upright position on a magnetic handing of 160 degrees.

The fuel tanks were ruptured and fuel-fed ground fires did occur. The leading edge of the left wing, inboard of the No. 2 engine, and the fuselage from the aft pressure bulkhead to the cockpit entry door were extensively damaged by fire.

The retract cylinders for the nose gear and both main landing gear were recovered, examined and found to be in the fully extended position.

The flap actuators were examined and measurements of 6-1/2 inch extension of the inboard actuators and 4-1/2 inch extension of the outboard actuators were taken.
