As I entered the pattern at my home airport (PSX), began to set up for my approach, selected the landing gear down position, to my amazement nothing happened. I checked circuit breakers and re-selected gear down. Again, nothing happened. After collecting my thoughts, mostly about the destruction of a beautiful aircraft during a gear up landing, I began the emergency procedure. Immediately upon opening the dump valve, the hydraulic pump came on. I closed the dump valve and soon had three green lights. The rest of the approach and landing was routine. My question to the group is.............does this suggest a problem with a pressure sensor and are there any other possible explanations for what happened? My landing gear circuit was upgraded during construction and includes: Bosch relays, full bridge wave, circuit breaker in the signal power to the main power relay. The aircraft has 40+ hours since new with absolutely flawless performance until now. Rocket Man-LNC2/233L Robert Robert W. Johs Dow Chemical Co.
