What happened
On July 13, 2009, a BEECH G18S, registration N93CA, was performing a Part 135 cargo flight when it experienced a runway excursion at Yakutat, Alaska. During the landing phase, the pilot had the main wheels on the ground and was in the process of lowering the tail when a direct crosswind gust, estimated by the pilot at approximately 15 knots, struck the aircraft.
The pilot attempted to counteract the gust by increasing power to the upwind engine; however, the pilot was unable to maintain control. Consequently, the pilot reduced power to both engines and applied the brakes. The aircraft subsequently exited the runway and performed a 150-degree left turn. During this excursion, the right main landing gear collapsed, resulting in substantial damage to the right wing. There were no injuries resulting from the accident.
The investigation
The investigation reviewed the pilot's statements and the aircraft's condition. Prior to the accident, there were no known mechanical issues with the aircraft. Weather conditions at the time were reported as VMC with a visibility of 10 statute miles and winds of 240 degrees at 06 knots.
