It was determined that the copilot was the PIC at the time of the accident and he failed to level off properly. An excessive load upon touchdown caused the right main gear to collapse.
The following factors were considered as contributing:
- inadequate supervision of flight on part of the captain,
- pilot fatigue,
- seat belt not fastened,
- overload failure.

Circumstances:
The aircraft christened 'Clipper Racer' departed San Francisco on a cargo flight to Cam Ranh Bay, Vietnam with en route stops at Elmendorf AFB, Tokyo and Đà Nẵng. Because of below minima weather at Anchorage International Airport, the aircraft landed at Elmendorf AFB. Several delays were experienced before the flight taxied out at 06:02. Flight 799 was given a void time of 06:15 by Oceanic Control to avoid traffic conflict. If the crew failed to make that time, it would result in a 45 min delay. When the checklist item "wing flaps" was called, the 'follow me' truck arrived to guide them to runway 23. From then on the crew were busy steering the plane on the slippery taxiways and talking to Oceanic Control resp. The aircraft was cleared for takeoff at 06:14. The stick shaker sounded shortly after VR (154 kts). The aircraft rotated climbed slowly. The right wing contacted the snow covered ground 94 feet left of the extended centerline at a distance of 2760 feet from the runway. The aircraft rolled inverted and broke up.
Probable cause:
An attempted takeoff with the flaps in a retracted position. This resulted from a combination of factors:
- Inadequate cockpit checklist and procedures,
- A warning system inadequacy associated with cold weather operations,
- Ineffective control practices regarding manufacturer's Service Bulletins,
- Stresses imposed upon the crew by their attempts to meet an air traffic control deadline.

Circumstances:

Probable cause:
The accident was probably caused by the combination of the following factors:
- The pilot-in-command continued under VFR mode into adverse weather conditions,
- Delayed in initiating go-around,
- Downdrafts,
- Obstruction to vision,
- Blowing snow,
- Pilot lost visual reference due to blowing snow.
