Description

On 19 March 2009 a BAe 146-200 being operated by South African Airlink on a scheduled passenger flight from George to Cape Town in day Visual Meteorological Conditions (VMC) experienced a flameout of all four engines during the landing roll at Cape Town. The aircraft had enough momentum to roll forward on the runway and vacate onto a taxiway and the APU continued to provide electrical power to the hydraulic system, which facilitated braking and directional control. It was then towed from the taxiway to the apron and the passengers disembarked normally.

Investigation

Upon becoming aware of the event, which was not reported as a Serious Incident by the aircraft operator, an Investigation was commenced by the Accidents and Incidents Investigations Division of the South African CAA.

It was found that during the landing roll at George immediately prior to the incident flight, the aircraft had experienced a double engine flameout. This had been accompanied by abnormal indications for the Thrust Modulation System (TMS), a limited authority auto throttle system installed as standard on this aircraft type. Line maintenance attention after this occurrence had been unable to find any related fault but extensive engine ground runs had been performed with no recurrence and so the aircraft had been released to service.
