Narrative:
A Douglas DC-3, operated by Arall Colombia, was destroyed by fire following a forced landing near Puerto Gaitán, Colombia. The three occupants were injured.
The aircraft took off from runway 04 at Puerto Gaitán Airport about 06:22 hours local time. Upon rotation of the aircraft, the crew heard an explosion from the no.1 (left) engine. The pilot noticed that the no.1 engine cover had torn away, hitting the propeller blades. The aircraft began to lose height and speed and the crew decided to perform an emergency landing in a field.
The aircraft struck the ground causing detachment of the propellers and parts of the aircraft. After coming to rest, a post-impact fire started that consumed much of the aircraft.
An inspection of the engine revealed that one of the cylinder heads had broken away. Parts were found near the end of the runway.

Probable Cause:

Probable cause:
Wrong application by the crew of the emergency procedure due to engine No. 1 failure, since they reduced the RPM of the operative engine (No. 2), causing the BMEP limit to be exceeded, producing an engine stall (No. 2), making the flight of the plane impossible and forcing the execution of a forced landing.

Contributing Factors:
Engine failure No. 1, caused by the detachment of the head of a cylinder during take-off.
Deficient maintenance procedures that did not anticipate or prevent component failure.

Follow-up / safety actions

Aerocivil issued 6 Safety Recommendations

Issued: 05-FEB-2019	To: Arall	REC. 01-201613-1
Provide training to the crews of the DC3 team, in which procedures are reviewed in case of engine failure, in different phases of flight, emphasizing the correct and orderly execution of the same, applying the Management of Cabin Resources. Also, review the limitations of the engines and the aircraft, and the performance of this in flight with a single engine.
Issued: 05-FEB-2019	To: Arall	REC. 02-201613-1
Review and update the General Operations Manual, the Training Manual and the DC3 Checklists, so that they contain the standard procedures to be followed by crews in case of engine failure, in different phases of flight, establishing the roles and obligations of each Crew Member.
Issued: 05-FEB-2019	To: Arall	REC. 03-201613-1
Improve the procedures of control of the aircraft and flight records of the flight crews in their charge, avoiding as much as possible that the same Pilot of the company is the one who carries the administrative load and the control of the hours flown.
Issued: 05-FEB-2019	To: Arall	REC. 04-201613-1
Review the maintenance programs of the R-1830 engines of the DC3 equipment, taking into account that due to their age and the effort to which they are submitted, it is necessary to establish inspection and testing programs, more frequent than those established by the manufacturer.
Issued: 05-FEB-2019	To: Arall	REC. 05-201613-1
Strictly comply with the provisions of RAC 114, in relation to the Operator\'s obligation to arrange for the inspection of post-accident components as ordered by the Investigating Entity, and assume the costs of the investigation to which it is entitled.
Issued: 05-FEB-2019	To: Aerocivil	REC. 06-201613-1
Through the Secretariat of Operational Safety and Civil Aviation, make this Investigation Report known to the Commercial and Private Aviation Operators operating the Cessna 206 team, so that they may apply the recommendations, as appropriate, and take into account the Report to improve the Operational Safety Management Systems.
