Narrative:

I was flying a light twin in to syracuse airport at dawn to pick up one person whom I work for. On extended base leg I put the gear handle in down position, with no indication of drag factor, green light or visibility nose gear down. I then proceeded to check cbs, gear handle (cycled several times, but could only get a red light for gear in up position), and checklist. After realizing I wouldn't get the gear down, I told the appropriate ATC facility, they then gave me vectors (still VMC) so that I would have time to manually extend the gear. I proceeded then to follow the emergency checklist in the airplane and manually extended the gear. After getting a visibility indication on nose gear down and green light, I landed on syracuse airport. Everything was working fine, and the rescue vehs were not needed. I was then sure the gear motor was not working, I visly inspected the landing gear on ground and then (since it was early am and no mechanic was available in syracuse) called my mechanic that does all the work on the airplane normally. He is located at the same airport that I'm flying out of about 30 NM from syracuse airport. I flew with the gear in down position back to my base, and put the airplane up on jacks to check it out. The motor (for the gear) had a flat spot and that's why the gear wouldn't extend. The airplane has approximately 5000 hours and the gear motor the same. To avoid problems/incidents like this in the future, maybe it would be a good idea to replace or overhaul the gear motor every once in a while.

Title: CORP ACFT HAS GEAR EXTENSION PROBLEM. MANUALLY EXTENDS, SAFE LNDG.

Narrative: I WAS FLYING A LIGHT TWIN IN TO SYRACUSE ARPT AT DAWN TO PICK UP ONE PERSON WHOM I WORK FOR. ON EXTENDED BASE LEG I PUT THE GEAR HANDLE IN DOWN POS, WITH NO INDICATION OF DRAG FACTOR, GREEN LIGHT OR VIS NOSE GEAR DOWN. I THEN PROCEEDED TO CHK CBS, GEAR HANDLE (CYCLED SEVERAL TIMES, BUT COULD ONLY GET A RED LIGHT FOR GEAR IN UP POS), AND CHKLIST. AFTER REALIZING I WOULDN'T GET THE GEAR DOWN, I TOLD THE APPROPRIATE ATC FAC, THEY THEN GAVE ME VECTORS (STILL VMC) SO THAT I WOULD HAVE TIME TO MANUALLY EXTEND THE GEAR. I PROCEEDED THEN TO FOLLOW THE EMER CHKLIST IN THE AIRPLANE AND MANUALLY EXTENDED THE GEAR. AFTER GETTING A VIS INDICATION ON NOSE GEAR DOWN AND GREEN LIGHT, I LANDED ON SYRACUSE ARPT. EVERYTHING WAS WORKING FINE, AND THE RESCUE VEHS WERE NOT NEEDED. I WAS THEN SURE THE GEAR MOTOR WAS NOT WORKING, I VISLY INSPECTED THE LNDG GEAR ON GND AND THEN (SINCE IT WAS EARLY AM AND NO MECH WAS AVAILABLE IN SYRACUSE) CALLED MY MECH THAT DOES ALL THE WORK ON THE AIRPLANE NORMALLY. HE IS LOCATED AT THE SAME ARPT THAT I'M FLYING OUT OF ABOUT 30 NM FROM SYRACUSE ARPT. I FLEW WITH THE GEAR IN DOWN POS BACK TO MY BASE, AND PUT THE AIRPLANE UP ON JACKS TO CHK IT OUT. THE MOTOR (FOR THE GEAR) HAD A FLAT SPOT AND THAT'S WHY THE GEAR WOULDN'T EXTEND. THE AIRPLANE HAS APPROX 5000 HRS AND THE GEAR MOTOR THE SAME. TO AVOID PROBS/INCIDENTS LIKE THIS IN THE FUTURE, MAYBE IT WOULD BE A GOOD IDEA TO REPLACE OR OVERHAUL THE GEAR MOTOR EVERY ONCE IN A WHILE.
