Nick,  I  am trying to come up with a  combination tie down point / jack pad. The access to the wing is thru the bell  crank hole which is 98" from the fuse. I would expect to have 400 lbs. on the  jack pad and was wondering if the spar would support that weight  in that  area.  How do you now support the plane for service of a tire or gear  ?  Your input would be greatly appreciated.   Tex

Hi Tex,

     Let me jump in here and suggest that you will  probably need to provide Nick one additional piece of info for him to be able to  figure the actual forces you are talking about.  That additional info is -  how are you going to use the jack points?  What I mean by that is will you  only use one at a time to raise just one main wheel off the ground, or do you  intend to pick up the complete airplane by using both wing jack points and a  tail stand?  If you are only gong to lift one main wheel and leave the  other main wheel and the nose wheel on the ground than you don't have a 400  pound load near the area of the aileron bell chank.

     So far I have seen no need for a jack point as  there are two simple ways to pick up one wheel for maintenance.  One way,  just have someone get under one wing (on their hands and knees) out about mid  span or more and push up under the spar.  When they have the main gear up,  place a padded crate (or saw horse -something to hold the wing up) so your buddy  is not on his knees for too long a time.  The other way, is to find a small  scissor jack (like came with the older Corvettes) that will actually fit under  the main gear leg bottom fitting and just jack up that wheel.  I have also  used a floor jack but sometimes I need to air the tire up a little to get the  floor jack to fit under the lower gear leg fitting.  I have used all of the  above procedures on both Lightnings and Esquals with no problems.  

     But your idea of having a jack point in each wing  will certainly come in handy when you are doing landing gear retract test.  

 Blue Skies,

 Buz

Another way is to use a cheap ATV jack.  They go down flat and lift fairly high.  You can always put a box with padding on top of it to increase the height.  I found one used for $35.00.  

   

Here’s a link to what they look like.

Tex,

  

 In the  shop we use the "handy jack" that can be found here: http://aviationtechproducts.com/html/products_pics.html#RVJACK.  It uses a cable that wraps around the axel on the inboard side of the wheel.  This device along with a floor jack works very well for us.

  

 If  we've needed to service the gear leg or axel then we've used Buz's  method.

  

 Hope  this helps.

  

 Mark
