Discussion on a couple points?
Helmets: SA2000 is the minimum requirement for helmets in the CCR and neither 2018 AI or CMC rules express anything otherwise. So any homologated SA/FIA helmet from 2000 on is OK.
With the changes in helmet standards since 2005 (and particularly 2015) related to pre-fitted terminals for head/neck and other topics, it seems the CCR should be updated to reflect current certs? Too much has changed since 2000 IMO.

Nets: Safety nets are not called out with any expiration but our window nets did/do have a tag indicating expiration. Right side did not expire and I don't see any tag on any of ours.

Fire systems: if you have not done a discharge test or at least refilled in 5 years, you might want to do so.
