## Discrepancy

DURING TAKEOFF, THE CREW REPORTED THE RH GEAR DOWN/LOCKED (GREEN) LIGHT DID NOT EXTINGUISH AND THE TRANSIT LIGHT STAYED ON. THE CREW FOLLOWED THE AFM PROCEDURE AND RESET AND ATTEMPTED A SECOND GEAR RETRACTION WITH NO SUCCESS. MX PERFORMED MULTIPLE GEAR SWINGS AND COULD NOT DUPLICATE THE DISCREPANCY. THE EVENT WAS DISCUSSED WITH TEXTRON TECH SUPPORT AND AT THEIR RECOMMENDATION, WE REPLACED THE RH GEAR REGEN SHUTTLE VALVE. OPS CHECK AND FLIGHT EVALUATION WERE SATISFACTORY.
