Accident Overview
The pilot of a twin-engine airplane reported that the left engine lost power while cruising at 7,000 feet MSL. After feathering the left propeller, the airplane continued to lose altitude. The pilot was unable to maintain altitude and subsequently performed a forced landing into treetops.
Landing Gear Issue
Throughout the flight, the pilot reported that the main landing gear kept sagging, requiring him to place the main gear selector in the up position every 3 to 5 minutes. The pilot stated that the gear problem was apparently caused by a slow leak in the hydraulic system and that the issue had been scheduled for repair.
Pilot's Assessment
In a written report to the NTSB, the pilot expressed that in retrospect, the seemingly minor gear problem may have been of critical significance in causing the accident. He noted that he might have been able to recognize the gear issue as a source of drag and avoid the crash landing.
Engine Examination
An examination of the left engine after the accident disclosed water and debris in the fuel system, as well as blackened spark plugs.
