## Discrepancy

(CAN) OPERATOR REPORTED THAT THE AIRCRAFT ABORTED TAKE OFF - DUE TO THE SPOILERS DID NOT RETRACT: TAKE OFF WARNING HORN CAME ON - CREW ABORTED TAKE OFF AND RETURNED TO RAMP. MAINTENANCE CREW FIGURED OUT DURING TROUBLE SHOOTING, THAT THE MICRO SWITCH IN THE PLA-QUADRANT DOES NOT TRIGGER, WHEN POWER LEVER IS MOVING FORWARD. PLA-QUADRANT CHANGE SOLVED THE PROBLEM.
