Airbus has issued a service bulletin (SB) requiring A300-600 operators to de-activate thrust reversers after a Korean Air aircraft suffered reverser deployment after take-off. The A300s affected are those with Pratt & Whitney 4000 engines, for which P&W also makes the reversers.

The event occurred shortly after take-off from Jakarta, Indonesia, on 22 November and caused a momentary roll to the left. Airbus says that the reverser deployed for "a few seconds". The pilot de-activated the reverser and returned to Jakarta. The SB will remain in force until the cause of the deployment has been determined, says Airbus. Some 35 airlines and 190 aircraft are affected.
