The aircraft departed Vancouver at 19:18. The first officer was the flying pilot. When the aircraft arrived at Sandspit, the surface wind was strong, gusty, and across the runway (220 degrees magnetic at 30 knots, gusting to 37 knots). The crew conducted an instrument approach to runway 30, and the airplane touched down on its belly. After initial contact with the runway, the aircraft bounced several times with diminishing force as it slid down the runway. It then veered to the right side of the runway, breaking five runway lights with its right wing, veered to the left, and came to a stop about 500 feet from the end of the runway. FINDINGS AS TO CAUSES AND CONTRIBUTING FACTORS: “The crew did not complete the before-landing checks, ignored aural warnings, and did not lower the landing gear, which resulted in a gear-up landing.”
