An Operations Engineering Bulletin ( OEB) is issued to rapidly inform operators of any deviations from initial design objectives that have a significant operational impact. An OEB provides the operators with technical information and temporary operational procedures that address these deviations.
TYPE OF OEB
OEBs can either be red or white, depending on their level of priority:
RED OEBs are issued to indicate that non-compliance with the recommended procedures may have a significant impact on the safe aircraft operation of the aircraft.
WHITE OEBs are issued to indicate that non-compliance with the recommended procedures may have a significant impact on aircraft operation.
Airbus strongly recommends that all Operators rapidly apply the OEB corrective actions as soon as they become available, particularly for red OEBs.
OEB CONTENT AND MANAGEMENT
An OEB:
Is temporary and usually focuses on one operational subject only,
Is included in the OEB section of both the FCOM and QRH. The procedural part of each white or red OEB ( OEB PROC) is provided in the OEB section of the QRH, so that the flight crew can easily access the procedures,
Remains applicable until the appropriate corrective actions are completed.
Note:
After installation of the OEB corrective modification/Service Bulletins (SB): if an Operator reinstalls any spare equipment for which there was an OEB associated to, it is Operator’s responsibility to ensure that this OEB be applied again for the applicable aircraft.
OEB IN THE FCOM
The content of each OEB includes:
The reason for issue,
Technical explanations of the deviation from the initial design objectives,
The operational impact of not applying the OEB procedure,
The conditions for applying the OEB procedures:
ECAM warning/caution affected by the OEB,
Cockpit effects,
Flight phases,
Specific event.
The OEB operational procedure(s) to be applied,
The corrective actions that cancel the OEB, (if available),
The OEB REMINDER codes, (if applicable).
I mean simple reading is sufficient, isn't it? Please read it till there's no more doubt.
