A pilot experienced multiple failures during a night cross-country flight, including instrument lights, flashlight, vacuum pressure, electrical system, and engine power, resulting in a forced landing in trees.

Departure and Initial Issues

During departure preparations, the pilot reported that the engine could not be started. After the battery was changed, the engine started. However, following engine start, the instrument lights did not illuminate. Despite this, the pilot elected to continue the night cross-country flight.

In-Flight Failures

Approximately one hour into the flight, the pilot's flashlight failed. Shortly thereafter, there was a loss of vacuum pressure, leading to a subsequent loss of the vacuum-driven instruments. Moments later, while at 3,500 feet mean sea level, the pilot stated that all electrical power was lost, followed by a total loss of engine power.

Forced Landing and Post-Accident Testing

With no engine power, the pilot executed a forced landing in a wooded area, colliding with several trees. Following the accident, the engine, alternator, vacuum pump, carburetor, and magnetos that were on the airplane at the time of the accident were tested and found to function normally through all ranges of power settings.
