The Australian Transport Safety Bureau (ATSB) is investigating flight control event involving Boeing 737-800, registration VH-YFZ, at Gold Coast Airport, Queensland on 27 April 2022.

During initial climb and again on approach, the crew reported reported an uncommanded roll to the right and cabin crew reported abnormal noise during the climb. The engineering inspection revealed the outboard left flap was skewed to the right. The inspection also found damage to the hardware associated with the flap’s operation, including the inboard program roller and support which had fractured and departed the aircraft.

The evidence collection phase of the investigation will include interviewing the crew, analysing recorded data and examining the relevant components.

A report will be published at the conclusion of the investigation. However, should any critical safety issues be identified at any stage during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate safety action can be taken.
