The airplane impacted a light post, a hotel, and terrain shortly after takeoff. The pilot reported that the ground roll and liftoff seemed normal. He reported retracting the landing gear and flaps while at a 300-foot/minute climb at 90 miles/hour. He said the flight encountered a downdraft shortly after that during the takeoff initial climb at around 200 to 300 feet above ground level. When the flight encountered the reported downdraft, the engine instruments indicated that both the front and rear engines were producing 24 inches of manifold pressure and 2,500 rpm. The pilot said he was unable to arrest the descent prior to colliding with the hotel and light post. Post-accident examination of the aircraft and engines provided no evidence of a malfunction or failure that would have precluded normal operation of the engines. Review of the closest weather facility's recorded weather data (located 17 nautical miles away) revealed the flight had a likely headwind of 11 knots and a computed density altitude of 4,903 feet. The calculated performance data revealed that the airplane should have been able to climb about a rate of 850 feet/minute with both engines operative and at normal climb speed of 109 miles/hour.
Probable Cause: the pilot's encounter with a downdraft or wind shear during takeoff the initial climb.
