A 2013 paper covering the MoD Helicopter Safety Enhancement Programme stated,
There is currently no wire cutter kit developed for the Chinook and there are no known plans to develop one. The cost and timescale associated with introducing this capability suggest that an alternative means of protecting the aircraft against wire strike may be a better option. Assessment of a tablet based moving map capability is underway, which would have details of known wires and obstacles overlaid. The key to this type of system is considered to be an effective means of alerting the aircrew to the presence of wires without them having to spend prolonged periods “eyes-in”.
I hope the ODH found suitable mitigation to cover the wire strike risk when he signed off on the ALARP safety statement.
