A Beech A100 aircraft, departing Barrie-Orilia to Windsor, Ontario, Canada, experienced a catastrophic landing following a series of malfunctions during the flight. The aircraft remained in a ‘red light’ state when landing gear was raised, and the right main gear was not illuminated despite crew action. The aircraft diverted to North Bay for maintenance, where the right main gear collapsed, resulting in propeller damage to the runway. Passengers were evacuated safely, with no injuries.A Beech A100 aircraft, departing Barrie-Orilia to Windsor, Ontario, Canada, experienced a catastrophic landing following a series of malfunctions during the flight.
