## Analysis

The non-certificated pilot was conducting a local flight near a friend’s residence in an unregistered airplane. There were no witnesses to the accident. Following the accident, a local law enforcement officer briefly talked to the pilot, but no information was provided during this, or subsequent interview attempts to explain the sequence of events that preceded the accident. The airplane sustained substantial damage to the left wing and forward fuselage. Based on the available evidence, the reason the airplane impacted terrain could not be determined.
