## Discrepancy

(CAN) FLAP POWER CAUTION LIGHT ON GROUND REPORTED BY FLIGHT CREW. FLAP CAUTION ILLUMINATED WHEN SELECTING 0 TO 5 WITH RUNNING ENGINE. FLAP STUCK AT 0 POSITION. MAINTENANCE REPLACE THE FLAP PRESSURE SWITCH DUE TO A PREVIOUS EVENT ON 25 MAY 2019 THAT WAS CORRECTED BY QRH PROCEDURE. CREW HAD SHUT DOWN BOTH ENGINES WHILE FLAPS WERE BETWEEN 10 AND 15, THEN FLAP POWER CAUTION LIGHT CAME ON. (TC# 20190607007)
