Circumstances:
After takeoff from Villavicencio-La Vanguardia Airport, while climbing to an altitude of 1,900 feet, the captain reported severe vibrations with the left engine and was cleared to return. The crew shut down the left engine and started the approach to runway 22. But on final, he realized he could reach the airport so he completed a belly landing one km short of runway threshold. The aircraft came to rest in a field and was damaged beyond repair. All 20 occupants escaped uninjured.
Probable cause:
It was determined that the vibrations and the subsequent failure of the left engine was the consequence of a bad adjustment of the intake valves on cylinders n°8 and 9, which remained stuck in open position, causing high temperature and a loss of power.
