Beech A100 King Air Landing Gear Failure at Ottawa

Flight Operations and Initial Incident On the day of the occurrence, a Beech A100 King Air with serial number B-103 departed Ottawa MacDonald-Cartier International Airport at 0830 eastern daylight saving time for an instrument flight rules (IFR) training flight to North Bay, Ontario. The aircraft was operated by two flight crew members. Upon arrival at North Bay, the crew completed a radar-vectored back-course approach to runway 26, performing a touch-and-go landing followed by two visual flight rules touch-and-go landings and a full-stop landing. After switching seat positions, the crew departed on a return IFR flight to Ottawa. During the approach to Ottawa, the crew selected the landing gear down and observed an unsafe landing gear indication. They requested and received overshoot instructions from air traffic control. Ground observers confirmed that the landing gear was not extended. The crew initiated the emergency landing gear extension procedure, but the cockpit continued to display an unsafe indication for the right main landing gear, even though ground observation suggested the gear appeared extended. The crew requested emergency rescue services and proceeded to land on runway 25. During the landing roll, the right main landing gear collapsed, causing the aircraft to veer right and exit the runway onto the grass infield. The aircraft came to rest on a northerly heading, 3,000 feet from the runway threshold. No injuries were reported. The accident occurred in daylight under visual meteorological conditions.
