Investigation Details
According to the official report, the pilot unexpectedly quit working and left home ten days before the accident. Seven days later, the pilot returned and left a suicide note. On the day of the accident, police officers questioned the pilot, who stated that the suicide note was left to get revenge on his wife. The officers did not detain him.
The pilot then departed from the airport in his airplane and flew for approximately 5 hours and 20 minutes. Witnesses at the accident site reported that the airplane circled the area and executed at least one diving, pull-up maneuver. After completing that maneuver, the aircraft entered a straight nose-down attitude and crashed into a house. There was no fire.
Witnesses described the engine sound as normal while the airplane was circling the area. During the descent, the engine sound increased to a high-pitched whine until impact.
Mechanical Condition
The investigation disclosed no evidence of any preexisting malfunctions or failures that would have rendered the airplane incapable of operation.
