During landing, a crosswind gust estimated at 15 knots caused a cargo airplane to veer off the runway, resulting in a 180-degree turn and collapse of the right main landing gear, damaging the right wing.

Accident Details

The pilot, who holds an airline transport pilot certificate, was conducting a cargo flight under Title 14, CFR Part 135. As the airplane touched down with the main wheels on the ground and the tail was being lowered, a direct crosswind gust struck the aircraft. The pilot estimated the gust at about 15 knots. He attempted to counteract the gust by applying power to the upwind engine, but this was insufficient. He then reduced power on both engines and applied the brakes. The airplane subsequently departed the runway, making a 180-degree left turn during the excursion. The right main landing gear collapsed during the event, causing substantial damage to the right wing.

Pilot Statement

In a written statement, the pilot acknowledged that he should have flown over the field to check the windsock before landing, rather than making a straight-in approach. He also stated that there were no known mechanical issues with the airplane prior to the accident.

Damage

The right wing sustained substantial damage as a result of the right main landing gear collapse. No other damage details were reported.
