What happened
During the takeoff phase, the pilot initially contacted ground control and was advised of wind conditions from 350 degrees at 13 knots, with gusts reaching 18 knots. Although cleared to taxi to runway 36R, the pilot requested runway 27R to utilize a longer runway length. After receiving clearance for takeoff on runway 27R, the tower controller updated the pilot that the wind was now from 020 degrees at 14 knots.
As the aircraft attempted the takeoff, the pilot reported that the main landing gear lifted off the ground, prompting an aborted takeoff. During the subsequent rollout, the aircraft traveled off the end of the runway, resulting in a landing gear collapse. The aircraft and crew were not injured.
Findings
The investigation determined that the aircraft was operating at a weight at least 500 pounds over its maximum gross weight. Furthermore, the pilot failed to perform necessary weight and balance calculations prior to departure. It was also noted that the cargo within the aircraft was not properly secured.
