The airplane was substantially damaged when it impacted trees and terrain during initial climb from a 4,200 foot long hard surfaced runway. The pilot reported the airplane had full fuel and 3 passengers. The pilot stated that for the takeoff he selected 20 degrees of flaps, rotated the airplane about 60 miles per hour, and kept the airplane in ground effect to gain airspeed. He stated that during the climb the wings started to stall. The pilot lowered the nose to regain airspeed, but impacted 70 foot high trees at the departure end of the runway. The airplane flight manual recommends no flaps for normal and obstacle clearnace takeoffs and flaps 10 degrees to shorten ground run. It does not recommend flaps settings of 30-40 degrees. Based upon the airport's weather observation temperature data, the density altitude was 2,332 feet mean sea level with a relative humidity of 51 percent.
Probable Cause: The pilot's inadequate takeoff procedure with the use of 20 degrees of flaps. Contributing factors were the interrelated effects of high aircraft weight, the density altitude, and the relative humidity. An additional factor was the trees.
