Sequence of Events
After refueling, the pilot took off from a 3000-foot runway located in a mountainous region. The pilot reported that after a normal rotation and lift-off, a positive rate of climb was established. However, shortly after takeoff, during gear retraction, the aircraft began to settle.
Pilot Report
According to the pilot, the settling occurred when the aircraft encountered either a strong downdraft or a windshear condition. As trees became visible, the pilot increased the pitch attitude, but the aircraft struck the treetops.
Outcome and Damage
The aircraft continued flying and was safely landed at another airport. The leading edges of the wings, the right wing tip, the left flap, and the left horizontal stabilizer were damaged.
Airport and Conditions
The pilot stated that the airport was located on a mountain top which was surrounded by higher mountains. The density altitude was approximately 4500 feet.
