I believe the procedure described by the Chicago ACO paper (Eastin) and/or the Seattle ACO, augmented by Tom Swift's papers, are still the preferred guidelines for skin repairs and antenna penetrations.
If you absolutely must have the RAPID documentation, say for historical purposes, then see the attached files below.
You will need a PC with Windows 95 or 98 to install and run RAPID. Maybe XP will run it with some gentle coaxing.
In the unlikely chance that you are dealing with a structural failure in an aircraft, and you need to use RAPID is because it was the "substantiation" of a repair/penetration of the skin that has now failed, please let me know. I never deleted the old RAPID stuff from my archives, and could dig up more if you need it.
