Circumstances:
The twin engine airplane departed Popayán-Guillermo León Valencia Airport runway 26 at 14:06:06. The aircraft encountered difficulties to gain sufficient height. About 20 seconds after liftoff, at a speed of 82 knots, the aircraft rolled to the right then entered an uncontrolled descent and crashed onto two houses located 530 metres past the runway end. Two passengers were seriously injured and seven other occupants were killed.
Probable cause:
A loss of in-flight control of the aircraft due to possible excess weight. The aircraft probably managed to take off due to "ground effect", but, once in the air and out of ground effect, it was not able to obtain the speed that would allow it to safely accomplish the climb.
Contributing Factors:
- Absence of Dispatch procedures of the operator to perform a correct Weight and Balance of the aircraft, and the effective control of the boarded cargo.
- Incorrect calculation of the weight and balance of the aircraft by the crew, by not considering all the cargo that was loaded, causing the aircraft to take off with a possible excess weight.
- Weak operational safety management processes of the operator by not considering the operating characteristics of airfields such as Popayán (high altitude, high ambient temperature) that significantly limit the operation.
Final Report:

Circumstances:
The twin engine aircraft was completing a flight from Guaymaral to Popayán with an intermediate stop in Girardot, carrying four passengers and one pilot. The aircraft departed Girardot-Santiago Vila Airport at 1523LT. The pilot contacted Bogotá Control and reported his altitude at 4,200 feet bound to the west. At 1537LT, he received the QNH pressure. Two minutes later, while cruising in clouds, the aircraft collided with trees and crashed on the slope of a mountain, bursting into flames. The wreckage was found on Mt San Isidro five days later. The aircraft was destroyed by impact forces and a post crash fire and all five occupants were killed.
Probable cause:
Controlled flight into terrain after the pilot decided to continue under VFR mode in IMC conditions.

Circumstances:
The aircraft was chartered to transfer groups of prisoners from Medellín to Popayán on behalf of the National Penitentiary and Prison Institute. Fifty prisoners just disembarked at Popayán Airport when the crew departed on a ferry flight to Medellín for a second similar rotation. Popayán Airport is located at an altitude of 1,733 metres and its runway is 1,906 metres long. For unknown reasons, the crew decided to start the takeoff procedure from the intersection, reducing the available takeoff distance to 910 metres. Also, the flaps were deployed to an angle of 25° instead of 15° and the engine power was set at 95% instead of 100% as stipulated in the company procedures for airport located above the altitude of 1,400 metres. During the takeoff roll, at a distance of 150 metres from the runway end, the pilot realized he could not make it so he rejected the takeoff procedure and started an emergency braking manoeuvre. Unable to stop within the remaining distance, the aircraft overran, struck trees and came to rest, broken in two. Three passengers were killed while five other occupants were injured.
Probable cause:
Improper execution by the crew by not following the procedures, instructions and manuals of the aircraft manufacturer and approved to the SELVA company by the UAEAC, specifically when attempting to perform a takeoff in a wrong configuration, with a reduced power setting and an insufficient runway length for the execution of the procedure.

While all 12 occupants escaped uninjured, the aircraft was damaged beyond repair.
Probable cause:
Engine trouble in flight.
