Event Summary
Shortly after takeoff, the airplane struck a light post, a hotel, and terrain. The pilot reported that the ground roll and liftoff were normal. He retracted the landing gear and flaps while climbing at 300 feet per minute at a speed of 90 miles per hour.
Pilot Report
The pilot stated that during the initial climb, at approximately 200 to 300 feet above ground level, the flight encountered a downdraft. At that time, both engines were producing 24 inches of manifold pressure and 2,500 rpm. The pilot was unable to stop the descent before colliding with the hotel and light post.
Examination and Weather Data
Post-accident inspection of the aircraft and engines revealed no evidence of any malfunction or failure that would have prevented normal operation. Weather data from the nearest reporting facility, located 17 nautical miles away, indicated a likely headwind of 11 knots and a computed density altitude of 4,903 feet.
Performance Calculation
Calculated performance data showed that, with both engines operating and at a normal climb speed of 109 miles per hour, the airplane should have been capable of a climb rate of approximately 850 feet per minute.
