B. Aircraft Maintenance Configuration
(1)
Remove the LOCK-TORQUE SHAFT (FLAPS AND SLATS) WITH CLAMP-PIVOT from the applicable torque shaft.
(2)
Manually fully retract the flaps to the zero position (Ref. TASK 27-50-00-866-012).
(3)
Check the value shown on the label at the track 3 position. If the label shows a value different from '0', set the flap forward eccentrics to the zero datum position (Ref. TASK 27-51-00-820-004).
NOTE : The label is on the outboard side of the flap track beam.
____
(4)
