A malfunction of the landing gear system on a Cessna 337 resulted in the Air Attack crew having to land without the landing gear lowered. The incident occurred August 8, 2018 at the Lewiston-Nez Perce County Regional Airport in Idaho.
Thanks to excellent crew resource management everything turned out about as well as it could have, considering the pilot had to land the aircraft on its belly.
Below is the text from the preliminary report:
At approximately 1730 hrs Nxxx was on a 3 mile final for runway 30: while on final the pilot initiated extending the landing gear. Both the pilot and I had a routine of verifying gear extension/retraction by looking out the window and verifying the correct color of the landing gear lights on the instrument panel. While on 3 mile final we did not observe our landing gear through the window or have “3 green” lights indicating that our landing gear was down and locked.
The pilot cycled the landing gear lever and checked the circuit breaker: our landing gear did not extend. We notified XXX air traffic control tower that we were experiencing an issue with our landing gear and requested a low level fly by to have the tower provide visual confirmation of the status of the landing gear. The tower reported that our gear doors were open: however out landing gear was still retracted. Nxxx gained altitude and requested clearance to remain within the XXX airspace south of the field.
As we gained altitude we verified that we had approximately 1.5hrs of fuel remaining. I offered assistance to the pilot by asking “what can I do to help… what do you need from me?” the pilot handed me the emergency procedure checklist and asked me to find the “landing gear fails to extend” checklist. I located the checklist and began to read the checklist to the pilot over the ics system: actively participating in the emergency checklist trouble-shooting process. The emergency checklist instructed us to pull the circuit breaker for the electric hydraulic pump, extend the manual gear pump handle, pump 95 times and look for the landing gear to “extend”. Both the pilot and I attempted pumping the handle several 95+ pump cycles and the manual handle pumped easily without resistance. Based on the lack of resistance during the pumps we determined that we were not building hydraulic pressure. Continue reading “Air Attack aircraft lands without landing gear lowered”
