Read the full NTSB narrative

The pilot rented the airplane for a local flight with the passenger. While maneuvering, the airplane experienced a partial loss of engine power and the pilot could not maintain altitude. The pilot elected to perform a precautionary landing to a frozen lake and landed uneventfully. Examination of the engine revealed that the Number 1 cylinder intake valve had fractured. The cause of the failure could not be determined. The operator exceeded the engine manufacturer's recommended time between overhaul by over 1,600 hours. However, because the operator operated under Part 91, they were not subject to the Federal regulations that require compliance with manufacturers' recommended maintenance instructions.
