DEN99LA035

The pilot landed on runway 35, and the wind was west-northwest, 3 to 5 knots. He departed on the same runway approximately 15 minutes later. At approximately 20 feet above ground level, the flight controls became mushy, and the airplane went into an uncommanded roll to the left. After the pilot exited the airplane, he noted that there was a gully perpendicular to the runway's left side right at the location where he lost control. He further noted that the wind was now 200 to 220 degrees, 8 to 12 knots.

On January 31, 1999, approximately 1130 mountain standard time, a Mooney M20E, N5658Q, was substantially damaged when it impacted terrain during takeoff from Coronado Airport near Albuquerque, New Mexico. The instrument rated private pilot, sole occupant of the airplane, was not injured. The airplane was being operated by the pilot/owner under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the local flight which was originating at the time of the accident. No flight plan had been filed.

The pilot reported that he landed at the airport, on runway 35, approximately 15 minutes before the accident to drop off a passenger. He said that the wind sock indicated that the wind was west-northwest, at 3 to 6 knots.

According to the FAA inspector who interviewed the pilot, the flight was departing on runway 35 (4010 ft. X 60 ft., elevation 5280 feet) when the pilot operated flight controls became "mushy" and the airplane drifted to the left of runway centerline. The pilot reported that he was performing a short field takeoff when, at 20 feet above ground level (agl), the airplane went into an uncommanded roll to the left. He said that the left wing hit the ground and the airplane came to rest beside the runway. The inspector located the airplane approximately 1/3 of the way down the runway and approximately 50 feet left of the runway edge. The left wing was bent upwards approximately 45 degrees at the mid span of the left wing. The FAA inspector reported that he examined all flight controls and found them to have continuity with the airplane's controls.

The pilot stated that after he got out of the airplane, he noted that there was a gully which was perpendicular to the left side of the runway at the location where he lost control. He also noted that the wind had shifted to 200 to 220 degrees, at 8 to 12 knots (see attached diagram).
