Each of the seven sections in this chapter has a list that describes common repair procedures today’s rigger might use. While not necessarily encompassing everything, the techniques used in these repairs can be expanded upon to address almost any other scenario that might be encountered. This is acceptable data as referred to earlier in the chapter. If the rigger encounters a repair that he or she is not familiar with, then the rigger should contact the manufacturer for further direction and guidance. The rigger should also remember that each procedure is just one method of accomplishing a given repair. There might be more than one or an individual might develop a different technique to achieve the same results. The exception to this is approved data that requires a specific procedure, rating, equipment, materials, or repair process. 

No matter what techniques or procedures that are followed, remember that there are three basic requirements to follow for any proper repair procedure. 

1. Knowledge to do the job, to include the required certification and authorization 

2. Proper equipment, such as sewing machines or hand tools 

3. Availability of the proper materials 

The individual may be a master rigger with a complete parachute loft at his or her disposal but, without the materials as used in the original manufacture, the correct repair cannot be made. By following these simple guidelines, riggers are always able to determine whether or not they can do the job properly. 

Most of today’s manufacturers provide guidance for the repair and maintenance of their products. These instructions are the official guidelines that the rigger must follow. The 

four primary areas of parachute repair and maintenance are: canopy and lines; container; harness and risers; and accessory components. These areas are summarized within the seven sections of this chapter as follows: 

• Section 1—Canopy and lines 

• Section 2—Container 

• Section 3—Harness and Risers 

• Section 4—Accessory Components 

• Section 5—Alterations 

• Section 6—Manufacturing 

• Section 7—Miscellaneous 

## Section 1, Canopy and Lines 

There are two general categories of canopies: round and square. While there are other canopy types, their construction and repair techniques generally follow those of the round and square canopies. Figure 7-14  shows a round canopy repair table, created from current military manuals, and describes the types and limits of canopy repairs, most of which pertain to military or surplus canopies. It must be mentioned that all of the services differ in their approach to methods of repair. Those called out in this book are methods that have been proven to be practical and efficient and commonly accepted throughout the parachute industry. The techniques are similar with only minor differences in seam dimensions and tolerances. While these limits are practical from the technical point of view, the economic cost may not be in many cases. 

NOTE:  Ripstop tape is listed in the table as an acceptable repair for certificated round canopies; this table comes from military manuals that have not been addressed or updated
