5.2.8
Overlying Tape Repairs
Tapes overlying the parachute can be replaced as follows:
The damaged tape can be cut at the point where it joins the top rim tape. The tape should be
carefully unpicked and removed from the locating tape. The damaged tape should be measured
and a new section of tape measured. There should be a 250 mm longer than the damaged tape
to allow for the splicing of the load tapes as in 5.2.7.
As an additional guide, all tapes from the top rim to the crown ring are of equal length, so
measurement of adjacent tapes will provide further indication of correct tape length.
For diagram see Figure 4, Appendix C.
5.2.9
Envelope Cable Attachment Loops
Replacement envelope cables can be attached as follows:
a.
Unpick and remove the Nomex pocket over the affected tape.
b.
If there is any damage to the tape itself, then this must be unpicked 250 mm
(10”) beyond
the damaged area.
c.
Cut a new length of correct tape 250 mm
(10”) longer than the length removed.
d.
Stitch the new section of tape onto the existing tape, as shown in Section 5.1.2.3.
e.
Pass the new tape through the Nomex pocket.
f.
Turn the tape inside the envelope and stitch through both layers of tape and the
sandwiched fabric with the stitch patterns.
For diagram see Figure 5, Appendix C.
5.2.10 Envelope Cables (Stainless)
Stainless steel cables that are slightly discoloured due to overheating are safe provided they have
not become too flexible. Localised excessive flexibility in a flying wire indicates a weakening due
to loss of strength and wire temper. Wires affected in this way should be replaced. Wires that
are badly kinked or frayed should be replaced. If the wire
doesn’t spring back, it must be
replaced. If only one strand of an envelope cable has broken, the broken section can be covered
with heat resistant tape to prevent the ends of the wire causing damage to other parts of the
balloon.
Contact Lindstrand Technologies for further advice with regards to envelope suspension cables.
5.2.11 Parachute Centralising Lines
Before removing any damaged cords, measure the length of the relevant cord, or if it is broken,
measure the length of the cord adjacent to it. Mark each end of the cord with five marks spaced
50 mm apart. The marks are used as a reference when re-tying lines.
