Inspection after Flap/Slat Extension at more than the Flap/Slat Limiting Speed

TASK 05-51-13-200-001-A
Inspection after Flap/Slat Extension at more than the Flap/Slat Limiting Speed

1. Reason for the Job
This inspection is necessary after a crew report or an activation of the overspeed aural warning:

If the overspeed was not more than 10 Kts higher than the value shown on the VFE placard, only an extension and retraction test of the flaps and slats is necessary (refer to the operational test of the Flight Control Surfaces paragraph given in this procedure).

NOTE: If you find an unsatisfactory condition(s) during the operational test, the full inspection given in this procedure is applicable.

If the overspeed was more than 10 Kts higher than the value shown on the VFE placard, you must do the full inspection given in this procedure.
If an activation of the overspeed warning occurred during the movement of the flap and slat control lever (from position 0 to position 1), the inspection and the operational test of the flap system are not necessary (steps 4.C and 4.E.1 of this procedure).

NOTE: You can get confirmation of the slat and/or flap movement from the flight data recorder. If these data are not available, the maintenance procedures related to the pilot report are applicable.
