What happened
On May 12, 2018, a Cessna 182-B, registration LV-GTI, was conducting a training flight at the Coronel Olmedo aerodrome in Córdoba, Argentina. After performing routine inspections and engine checks, the pilot departed from runway 04 at full power. Shortly after takeoff, at an altitude of approximately 100 meters and a speed of 80 mph, the engine suddenly stopped without any prior warning or symptoms of malfunction.
Due to the low altitude, the pilot was unable to complete a turning maneuver to return to the runway. Instead, the pilot opted for an emergency landing in an open, unpopulated area within the aerodrome grounds. During the landing sequence, the aircraft struck a perimeter fence post that was obscured by tall vegetation. The impact caused damage to the horizontal stabilizer and the left elevator, and the aircraft eventually came to a halt 1s50 meters from the initial contact point. The pilot and passenger both exited the aircraft without injuries.
The investigation
The investigation focused on the sudden loss of engine power and the circumstances of the landing. Investigators examined the engine, the fuel, and the aircraft's maintenance history. While fuel samples from both tanks and the supply cistern were found to be suitable for use, investigators discovered particles within the fuel filter. Upon disassembling the carburetor, a significant particle was found at the base of the high-speed jet diffuser.
Findings
- The engine failure was caused by the obstruction of the jet diffuser by an insect, which prevented the necessary fuel flow for combustion.
- It is highly probable that the insect was drawn into the carburetor during the carburetor heat test performed by the pilot prior to takeoff.
- The aircraft's carburetor heat system lacks a filter to prevent the ingestion of foreign objects or particles.
- Although not a direct cause of the engine failure, the presence of a perimeter fence located outside the safety zone contributed to the structural damage sustained by the aircraft during the emergency landing.
