## Discrepancy

AFTER TAKE OFF, AND GEAR UP, THE RIGHT MAIN GEAR SAFETY LIGHT (GREEN LIGHT) REMAINED ON. INDICATING THE GEAR WAS STILL DOWN AND LOCKED. NO ADVERSE YAW WAS FELT SO WE CONCLUDED IT WAS JUST A STUCK SQUAT SWITCH AND RETURNED TO BASE. THE GEAR CAME DOWN NORMALLY, AND VERIFIED ON FINAL THAT THE GEAR WAS DOWN USING THE LANDING LIGHTS.
