What happened
The aircraft was engaged in a pipeline patrol mission when it experienced an unexpected loss of engine power. At the time of the incident, the pilot reported maintaining a cruise altitude of approximately 300 feet above ground level. Shortly after the power failure began, the pilot initiated emergency procedures to execute a forced landing.
During the descent and subsequent landing attempt, the aircraft collided with a utility pole. The impact resulted in significant damage to the airframe and engine components. No further details regarding injuries or specific location coordinates were provided in the source documentation.
The investigation
Following the accident, investigators conducted a physical examination of the aircraft's engine to determine the root cause of the power loss. The inspection focused on the intake system and internal engine components to identify any obstructions or mechanical failures that could have contributed to the event.
The examination revealed a critical blockage within the engine's induction system. Specifically, the carburetor venturi was found lodged in the number 2 cylinder intake port. This obstruction prevented proper airflow and fuel mixture delivery to the affected cylinder, leading to the loss of power.
Findings
The primary factor contributing to this accident was a mechanical failure within the engine's induction system. The carburetor venturi becoming lodged in the intake port directly caused the engine to lose power while the aircraft was at a low altitude. This mechanical issue left the pilot with insufficient time and altitude to complete a safe forced landing away from obstacles.
