Incident Overview
A pilot reported concerns about a potential fuel blockage to a mechanic during an annual inspection a few days before the incident. No evidence of fuel blockage was found at that time. On the day of the incident, the pilot attempted a takeoff from a wet, soft turf runway with the right fuel tank selected. During the initial climb after takeoff, the engine lost power, prompting the pilot to land on the remaining runway.
Second Takeoff and Forced Landing
Following the first power loss, the pilot initiated a second takeoff, this time with the left fuel tank selected. However, during the initial climb near the departure end of the runway, the engine again lost power. The pilot performed a forced landing, during which the airplane nosed over.
Examination Findings
A subsequent examination of the airplane revealed that the fuel gascolator was partially blocked with dirt and sediment. This blockage restricted the fuel flow to the engine, leading to the power losses.
