The pilot report noted 90-degree crosswinds with occasional gusts to 20 knots. The pilot said he touched down on runway 5 and a sudden crosswind gust raised the left wing and the airplane began veering off the runway. He reported that he applied opposite aileron and rudder, but was unable to regain directional control before encountering a drainage ditch where the airplane nosed over. ## Factual narrative On April 15, 1999, at 1445 hours mountain standard time, a Boeing A75N1, N53404, veered off runway 5, collided with a ditch, and nosed over during landing at the Casa Grande, Arizona, airport. The aircraft was owned and operated by the pilot and was on a cross-country personal flight conducted under 14 CFR Part 91 of the Federal Aviation Regulations.
