ARMY TM 10-1670-275-23&P AIR FORCE TO 13C5-25-2 NAVY NAVAIR 13-1-26 2-24.     Gore Section (cont). (b)   Pressure-sensitive  (iron-on)  patch.    The  method  of  applying  a  basic  patch  is  a  heat  and  pressure (iron-on) technique using pressure-sensitive-coated cotton balloon cloth.  This method is limited to use on the cotton muslin canopies such as the 12-foot cargo parachute.  A complete canopy section replacement will be performed when an individual section has been patched extensively with the pressure-sensitive patch material and an apparent stiffening of the section occurs.  The stiffening effect may adversely affect the proper layout and packing of a parachute canopy.  Apply a pressure- sensitive (iron-on) patch as follows: 1 Smooth all wrinkles from material surrounding the damaged area. 2 Cut a piece of pressure-sensitive-coated cotton balloon cloth large enough to extend 1 inch beyond all edges of the damaged area.  If damaged area extends to a point within 1 inch of upper lateral band, only a sewn patch as outlined in procedure (1) above will be allowed. 3    Place coated cloth patch over damaged area with adhesive side facing down.  If damaged area has no  material  missing,  patch  will  be  applied  to  the  inside  of  canopy  only.    Whenever  damaged  area has  a  space  between  the  edges  of  material  which  indicates  that  material  is  missing,  patch  will  be applied to both inside and outside of canopy (figure 2-44).
