SHORING
1. General
A. Shoring can be accomplished by using contour boards that conform to the lower wing and body surfaces. Contour boards should be made from four thicknesses of 1-inch plywood, laminated together and secured by bolts. The contour surfaces should be padded with 1/2-inch gray felt and covered with 10-ounce canvas duck.
B. Wing and aft body jacks should be used with wing and/or body shoring. All landing gear downlocks should be installed prior to shoring. The body should be supported at aft body jacking point during shoring of wing or body. Maximum loads at jacking points are tabulated below.
JACKING POINT MAXIMUM LOAD LBS.
97,800 GW TO 108,000 108,000 GW OR HIGHER
