N771RGMulholland Robert A VANS RV-7 · 2008

The pilot reported that, during the initial climb following a takeoff from takeoff from runway 10, the airplane encountered a wind shift that forced the airplane back to the ground and it departed the side of the runway. During the runway excursion, the airplane sustained substantial damage to the right wing. The pilot reported no pre-impact mechanical malfunctions or failures that would have precluded normal operation.

Before the pilot’s departure another airplane reported windshear, a 15-20 knot gain on final for runway 35R. Low-level windshear advisories were in effect at the time of departure, and when cleared for takeoff, the controller reported the wind from 340° at 9 knots.
