1 person was seriously injured.

A partial loss of engine power due to low cylinder compression. Contributing to the loss of engine power was rust formation in the cylinders due to inactivity.

Read the full NTSB narrative

The private pilot was conducting a local flight when the airplane's engine started to lose power. The pilot attempted a forced landing to a field; however, the airplane collided with trees. Examination of the airplane's engine noted that compression was low in all cylinders, and rust was present inside the cylinders. The airplane was not operated for about 4 years and had flown about 2 hours since being returned to service. The partial loss of engine power is consistent with a degradation in cylinder compression, and it is likely that rust formed in the engine during the time the airplane was not being used.
