Comment:
Compare the following anecdotal report with the autopilot disconnect major accident above.
Middle East operator A330 incident which went unreported in 2017. This operator's SOP requires autopilot to remain engaged until 300 ft AGL on all visual approaches.
On this particular occasion, the PF under line training disengaged AP at 1000 ft. The captain remonstrated with the PF in no uncertain terms that SOP required the AP disconnect should be at 300 ft not 1000 ft.
Captain then immediately re-engaged AP and shortly after permitted PF to disengage AP again as aircraft passed through 300 AGL. Normal landing then made. Blind adherence to SOP to satisfy a QAR read-out? The mind boggles.
