Narrative:
The Swearingen SA226-AT Merlin IV, HK-5225, belonging to the company Colcharter, was scheduled to perform two flights as an air ambulance, first from Barranquilla to San Andres (ADZ) and then with a patient to Medellin (EOH). The first leg was uneventful.
The controller cleared the flight to back track on runway 06/24 to the threshold of runway 06 for takeoff.
After having taxied about 200 m, the right engine apparently experienced a substantial periodic acceleration. After the right engine accelerated, there was a trajectory change to the left side of the runway centerline. The crew attempted to keep the aircraft within the runway, however, the crew's efforts did not have a positive result, allowing the aircraft to drift out of the runway into the safety zone. When the aircraft was over the safety zone, the crew attempted to use the braking system, however, the brakes were not effective due to the poor traction of the aircraft's wheels with the grass surface in the safety zone.
The aircraft continued to taxi to the left of the runway, until coming to a complete stop when the nose of the aircraft collided with a concrete wall bordering the airport.
The aircraft suffered substantial damage in the nose area, however, the stress concentration due to the impact was more evident in the left front fuselage area, structurally compromising a large part of the skin.
