Comanche gear collapse just waiting for an opportunity.

Thanks for posting this video. It will help me when I do my annual on my Camanche 260. I seen the amps test on the gear motor video it was great too. I find lot's of I&A don't really know comanche airplanes as much as I do. Andor A Koval

It is of great advantage to use a specialist in any field, and one who will be straight-forward with the analysis. Another issue that comes into play at some point is the financial one; that issue can cloud the solution. Whistle if I can be of any help. Matt

Please keep up the video posts - these are difficult issues to explain with just text! If a picture is worth a thousand words then these videos are worth a million.

Great for the fleet, great airplane, let's keep 'em flying!

Thank you for posting on the web. I've got a lot of dual-given in Comanches yet this is the real achiles heel of the design. A sloppy mechanic can let this get by on inspections and then the linkage is left not firmly over-center even though it's indicating down & 'green'.

Hi John: I think the 450 pound gorilla is a viable guess. The question then arises, when and where did the gorilla exit the gear well, over Florida or the Seattle area. Seriously, a columnar load could have done it but the pre-load would have to have been very poorly understood by the A&P to allow that loose condition. Then a lousy cross-wind landing with a bunch of sudden side load. Maybe the owner can shed some light on it, if he contacts me. It "baffles" me. Matt

Matt: What do you think caused the bend?

I saw another bent push-pull cable last spring near ELP. The owner's response to my discovery, "Why didn't the IA spot that?". I installed a new set of Webco's Teflon-lined push-pull cables. Matt
