High-strength joints or large patches may require use of double or multiple rows of rivets to obtain suffi-
CARGO BODY REPAIR (Cont).
Required rivet spacing is determined by strength needed in the joint. A general feel for strength re-
quired can be obtained by inspecting rivet patterns in surrounding areas.
Body repairs made using
single rows of rivets should be performed using rivet spacing not greater than 1.5 in. (4 cm) and not less
than 0.625 in. (16 mm). Use 1-inch rivet spacing as a general practice for repairs. Rivet spacing used
in original construction may be greater due to additional strength obtained by using epoxy adhesive.
Do not use rivet edge distances less than 0.375 in. (9.5 mm).
