Plain English Summary

3/10 complexity

This mandatory Airworthiness Directive requires owners/operators of Cessna 310R aeroplanes to complete specified safety modifications — including fuel bonding/earthing, instrument power supervision, external power‑socket protection, and cabin no‑smoking signage — by 30 September 1975. Some engineering modifications require approval by the Secretary. The measures reduce refuelling fire/explosion risk, ensure critical instruments warn of power loss, and protect the aircraft’s electrical systems.
