Plain English Summary

2/10 complexity

This rule requires that whenever a hot‑air balloon hose is disconnected while the other end remains attached to a pressurised LPG source, the open end must be fitted with a pressure‑seal blank (capped blanking fitting). It applies to all balloon operators and maintenance personnel.

Why it matters: it prevents pressurised LPG escaping during partial disconnection, shifting a small ongoing equipment and procedural cost to operators (who may instead choose to depressurise before disconnecting). The AD does not specify technical fitting standards.
