Unfallbericht:
ACES Flight 148 was prepared for a scheduled domestic flight to Bahia Solano and Quibdo. At 10:21 the engines were started and the crew received permission to taxy to runway 01. The flight was cleared for takeoff and departed Medellín at 10:29.

Probable Cause:

PROBABLE CAUSES: "Failure of the crew in the flight technique applied during the take-off phase, by not evaluating the performance of the aircraft, considering the high weight in front of the obstacles to climb over on the ascent trajectory.
Contributing Factors:
- Errors presented in the dispatch, since the weights were not totaled correctly, possibly due to errors in the handling of cargo and unaccompanied luggage.
- Attitude of complacency on the part of the crew, due to excellent meteorological conditions that caused an excess of confidence in the planning of the flight on the part of the crew.
