## Discrepancy

UPON SELECTING GEAR DOWN RIGHT MAIN EXTENDED NORMALLY, NOSE GEAR ABOUT 5-10 SECONDS LATER, LEFT MAIN INDICATED RED LIGHTS ONLY THEN NORMAL AFTER 45 SECONDS TO 1 MINUTE, THE GEAR WAS FELT THUD COINCIDING WITH GEAR DOWN INDICATION.  ADJUSTED LEFT OUTBOARD SEQUENCE VALVE.  OPS CHECKS GOOD.
