Aloha,
I have a problem with my landing gear and would like comments on possible causes. When the gear is raised it completes the cycle but the Hydraulic pump continues to cycle at a rate of about 1/2 second. All three gear remain up and apparently locked and the panel volt meter shows the cycling of the hydraulic pump. We are looking at the gear up hydraulic pressure switch and or the hydraulic power pack itself. We've jacked the plane and repeated the problem. Cycled the gear and pulled the hydraulic circuit breaker when up and the gear starts down very slowly ( more than 45 seconds before the nose gear starts down. Any additional test before pulling the pump and sending for analysis?
