Landing gear safetu cable

[Dravenelle]

Hi

My question is,,how long the safety landing gear cable loop (steel cable)can have for great operation (bungee gear)

I wish I could give a definitive answer but there have been several instances in the past when a hard landing resulted in damage to the Bungee bulkhead from too short cables. I know of of some who cut them out after the reports. A bit too long seems to be better than a bit too short short.

Here is a video on Bungee install.

I could measure how big the loop is hanging below the gear if you like;

I have 4 Kitfox here right now to look at.

What does the manual say? 2 to 3 " I would guess.

I would never not have them in place........... If a bungeee fails you gonna pay the price $$$$

If you are landing hard enough to do damage when the safety cable tightens to the limit and you bend your crossmember --well you had better do some basic flight training.

Enjoy the movie.

That's right Dave

I learned a long time ago not to argue with Dave. What I posted are veritable facts. Damage to the bulkhead on enough Kitfoxes to prompt guys to take some action. My choice was to go with Hammerhead gear. Welding in a new bulkhead was just not a viable choice. My advice still stands - a bit too long is better than too short. Just go with your best judgement and live with the consequences. By the way, can anyone document broken Bungee damage and $$$$ equalling a broken bulkhead.

The proper length for the cables is so that there is 4-1/2 to 5 inches of travel available at the ends of the landing gear shock cord arms.

Attached is a link to service letter #48 about the landing gear that shows an optional placement of the limit cables.
