Hello All,

I’m having landing gear problems and my local maintenance guys are stumped. I’m calling in the big guns (you) to see if this sounds familiar, or if you have a suggestion.

While in flight, below gear extension speed, gear selector is placed in down position; however, gear does not immediately extend and there are no signs that it is attempting to go down. Sometimes it finally comes down a minute later, sometimes it takes more time. When the lowering sequence does start, it progresses normally. Cycling the switch, when the gear are retracted, doesn’t produce any noticeable results. While the gear switch is down and the gear have yet to extend, the warning horn is audible when power is reduced. Problem has not been able to be reproduced on jacks after multiple attempts. The only hardware that has been replaced in an attempt to solve this issue was the main gear switch since the maintenance guys here are at a loss for any other explanation. Also, gear retraction in flight has had no issues. No recent maintenance has been conducted on the gear that may point to the cause. The problem was very intermittent about a year ago, but now it is happening on almost every flight. So far the landing gear always, eventually, comes down, but I’m ready for the emergency gear extension procedure to be needed at some point soon.

Any thoughts or suggestions would be greatly appreciated.

Kris
