The NTSB's narrative final · quoted from the NTSB record
The pilot reported that about 20 minutes into the flight, at an altitude about 500 ft above ground level, the engine started losing power. The pilot noted no anomalies on the engine monitoring system, but his attempts to increase engine power were unsuccessful, and he chose to conduct a forced landing in a lake. During the landing flare, the wheels contacted the water surface and the airplane nosed over and came to rest inverted and submerged. Examination of the airplane following recovery from the lake revealed that the fuel primer bulb was missing a spring on the fuel inlet check valve, which prevented the check ball from seating properly. This likely blocked the incoming fuel and thereby resulted in fuel starvation and the total loss of engine power.
