Gear won't retract.

Also the gear horn is not working. Don't know if the two problems are related, but they started at the same time.

Hi sorry about that but at least it happened at annual. Count your blessings. This appears to be an electrical problem. If the pump ain't a pumpin the nothing is going to move. When you cycle the gear see if there is any current to the electromechanical pump. If there is and no joy then the pump itself may need overhaul. When was it done last? If it was a long time ago then that could be your culprit. Also check for continuity at all the microswitches in the gear door assembly. If no current to the pump check the breaker that you would have pulled to put the gear down manually. See if the current passes through it ok. Sounds like a challenge. Let me know what happens. I will monitor this thread a little more.

Thanks for the ideas. I will check those items tomorrow. It acts like it could be a switch, because as soon as the nose wheel unlocks the motor cuts off.
