## Discrepancy

GEAR DISAGREE L AMBER CAS: LANDING GEAR DID NOT EXTEND WHEN THE GEAR HANDLE WAS SELECTED DOWN. WE CYCLED THE LEVER AND IT STILL DIDNT EXTEND. THEN THE AMBER GEAR DISAGREE L/R/N ILLUMINATED. AFTER GOING AROUND, WE COMPLIED WITH THE QRH AND MANUALLY BLEW DOWN THE GEAR. THE GEAR DISPLAYED THREE GREEN LIGHTS SO WE RETURNED AND MADE AN UNEVENTFUL LANDING. EMERGENCY VEHICLES WERE DISPATCHED AS A PRECAUTION.// SIGNOFF// REMOVED AND REPLACED LANDING GEAR HANDLE MODULE WITH A NEW MODULE IAW CE680A MM 32-30-30.
