Plain English Summary

2/10 complexity

This Airworthiness Directive requires owners/operators of De Havilland Heron (DH114) aeroplanes — except those already modified by DH Heron Mod. No. 604 — to have the centre‑section spar boom inspected for chafing using the manufacturer’s procedure (De Havilland TNS Series Heron No. F.10, Issue 2) by 31 December 1960. The regulator enforces the one‑time, date‑certain obligation; affected operators must arrange and pay for the inspection, creating an incentive to adopt Mod. No. 604 where available.
