Narrative:
Inadequate cargo restraint caused balance problems on takeoff, resulting in a very nose high attitude. The Skyvan banked right and left, crashed and caught fire. The certificated max. gross weight was exceeded by 324.8lb.

PROBABLE CAUSE: "Inadequate security of the cargo which shifted rearward during the takeoff roll. Factors which contributed to the accident were: the over gross weight condition, and the improper alteration of the tie down rings by the overhauling maintenance facility."
