Plain English Summary

This directive classifies helicopter external rescue systems (ERS) that hang below the landing gear as Class D external loads and requires them to be jettisonable. Non‑jettisonable ERS must be removed or modified with a Transport Canada‑approved jettison feature. (Requirement; Applicability.)

It applies to helicopter owners/operators and installers, who must pay for removal/modification and obtain approval by 31 December 2008. The change replaces prior permissive approvals for some non‑jettisonable STAs under updated Canadian rules. (Compliance; Background.)
