What happened
On December 28, 2021, at 15:12 local time, a Bombardier Aerospace Ltd., CL604, registered as G-XONE, was performing a private flight under Instrument Flight Rules (IFR) from Farnborough Airport to Bern Airport. The aircraft was carrying two crew members and six passengers.
As the aircraft was on short final for runway 14 at Bern, it encountered a sudden and significant negative longitudinal pitch while at an altitude of less than 100 feet above the ground. In response to this unexpected movement, the flight crew immediately initiated a go-around procedure. Following the aborted landing, the aircraft diverted to Zurich Airport.
The investigation
The Swiss Transportation Safety Investigation Board (SUST) opened an investigation into the incident to determine the cause of the sudden pitch change. The preliminary report notes that there were no injuries to the crew or passengers, and no damage was sustained by the aircraft or any third parties during the event.
