Narrative:

On jan/wed/02 (XA30) I made a takeoff at teb airport in a challenger 601. After takeoff, gear handle was locked and we could not raise the gear up. We elected to return to teb airport with the gear down. The approach and landing was normal. After landing and taxiing to the ramp, we investigated landing gear system. Everything was normal -- only evidence of a little ice between l-hand weight on wheel proximity switch. We cleaned off the ice and ran a cockpit functioning check. Everything indicated normal. There was no mechanical parts broken, no part was replaced and no repair was made and flight made it to destination that night. Next time if aircraft is parked outside when it is cold and raining/snowing, we will pay a lot more attention to this area on preflight.

Title: CL65 FLC WERE UNABLE TO RAISE THE LNDG GEAR AFTER TKOF AND RETURN LAND FOR INVESTIGATING THE CAUSE.

Narrative: ON JAN/WED/02 (XA30) I MADE A TKOF AT TEB ARPT IN A CHALLENGER 601. AFTER TKOF, GEAR HANDLE WAS LOCKED AND WE COULD NOT RAISE THE GEAR UP. WE ELECTED TO RETURN TO TEB ARPT WITH THE GEAR DOWN. THE APCH AND LNDG WAS NORMAL. AFTER LNDG AND TAXIING TO THE RAMP, WE INVESTIGATED LNDG GEAR SYS. EVERYTHING WAS NORMAL -- ONLY EVIDENCE OF A LITTLE ICE BTWN L-HAND WT ON WHEEL PROX SWITCH. WE CLEANED OFF THE ICE AND RAN A COCKPIT FUNCTIONING CHK. EVERYTHING INDICATED NORMAL. THERE WAS NO MECHANICAL PARTS BROKEN, NO PART WAS REPLACED AND NO REPAIR WAS MADE AND FLT MADE IT TO DEST THAT NIGHT. NEXT TIME IF ACFT IS PARKED OUTSIDE WHEN IT IS COLD AND RAINING/SNOWING, WE WILL PAY A LOT MORE ATTN TO THIS AREA ON PREFLT.
