Maintenance and Repair / Lifting a Lark (Jacking etc)
« on: July 25, 2017, 09:27:45 AM »
Hello,
(warned you the questions would be coming soon!) I need to get the weight off the wheels to inspect the oleos and wheel alignment.
Thanks to this site, I've found the quaint and excellent rigging manual for the PQ8, so I know that 'Station 91' is a good starting point. However, the text implies there should be jacking points 'attached' to the wing. On my Lark, there is no break in the canvas/wood to attach a tool, nor markings to confirm where station 91 is. Can a jack just be placed under the wings without any attachment? I'd be very worried about slipping...
A friend (non-aviation engineer) has suggested knocking up something to attach to the metalwork around the main gear mounting points.
I'd also like to get the aircraft stable on saw horses or similar, but again, there are no clear details of where they can be safely placed (just a very small illustration of the wing rigging process, with the weight of only the fuselage+engine on the stands).
Can anyone provide any more ideas/solutions for jacking the Lark?
