Jacking an airplane
 
Quick Google, but unable...

12,000 pound airplane (max), 3 point jacking - what size (capacity) jacks (3) do I need?

A simple, straight forward reply is appreciated. :ok:

Check AMM chapter 7.
Probably need two with 6000lb (3Tons) capacity and one for nose or tail about 2000lbs (1Ton) capacity.

Gentlemen, thank you. Is there some kind of ‘formula’ for jacking (jack size) an aircraft?

Again, thanks for your input!

If you want to do serious maintenance than do it according the manual.

I really tried to be 'nice' and thought I put out a couple of questions in a reasonable/responsible way...

The Learjet manual I have (chapter 7 is 13 pages...) gives part numbers for jack pads and a tailstand, but when it comes to jacks - it merely says 'commercially available' with no indication of rating.

This is a need at an A &P school to jack an unserviceable Lear.

Pretty typical (unfortunately) of Pprune though....

Thanks much.

These guys at TronAir have a solution. I suspect from your description you are looking to jack a Learjet 35, the link below relates to that, but if not their website allows you to enter different types.

188, Loose and Dr.,

Thanks a bunch for your positive (and helpful) input.

If 188 is as in L-, many fond memories of same - ahead of it's time.

Left Dubai end of last year after almost 9 years - have to say I miss it....

Long story, but in aviation well over 40 years and have never 'jacked' an airplane (or researched for that matter...), yes, I guess one could call that 'priceless'.....

Thanks again gents!
