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.
