Accident Summary
A pilot and his two passengers, including his son and 18-month-old grandson, sustained minor injuries when the Cessna 150 airplane struck trees and nosed over during takeoff from a private grass airstrip.
Witness Account
A witness observed the airplane takeoff and noted that it appeared slower than usual. The witness stated that the airplane typically gained altitude quickly after takeoff, but on this occasion it nosed-up and seemed to "plow forward" without gaining altitude. The airplane then banked hard left and hit trees before nosing over upon impact with the ground.
Pilot Report
The pilot reported that he taxied the airplane from the hangar onto the 2,000-foot grass airstrip and departed to the north. He stated that the engine was operating properly throughout the flight. The pilot noted that there were 100-foot trees located north of the departure end of the runway, but no obstacles to the south.
Inspection Findings
An inspection of the airplane revealed no pre-existing anomalies to the airframe or engine.
Environmental Conditions
The winds were from the east at about 9 knots. The local temperature was approximately 90 degrees Fahrenheit, resulting in a density altitude of about 2,914 feet.
Pilot Comments
The pilot reported that the accident could have been prevented by a "more thorough assessment of density altitude and choice of runway heading for departure."
