Narrative:
The takeoff was abandoned after V1 because the aircraft wouldn't rotate. The aircraft overran runway 07, collided with a fence, crossed a ditch, struck a hill and caught fire.
PROBABLE CAUSE:
Discontinuation of the takeoff run after the decision speed (V1) due to sensation problems by the pilot in the control of the aircraft in its pitching movement (transverse axis), during the rotation phase, which was caused by an erroneous adjustment of the horizontal stabilizer, without having been subsequently corrected, as a result of the overload in the front compartment of the aircraft and improper distribution of the same, causing the aircraft's Center of Gravity (CG) to move to the front to an extreme position. The above was not manifested in the Weight and Balance document, leaving the aircraft destroyed by impacts and fire upon entering irregular terrain at the end of the available runway length.
CONTRIBUTING FACTORS:
Deficiencies in the organizational and control system of the company operating the aircraft.
