Plain English Summary

3/10 complexity

Operators of historical and ex‑military aircraft flown under a Permit‑To‑Fly must, before each permit issue, inspect crew seat‑belt and harness attachment points and ensure they attach to metal structure or are modified to a method acceptable to the Civil Aviation Safety Authority. Introduced after a seat‑belt separation in a forced landing, the rule shifts recurring inspection and any modification costs and approval burden onto operators, with possible downtime and approval delays.
