Bell 407, WSPS™

The WSPS™ Wire Strike Protection System™ provides a measure of protection for helicopters in the event of inadvertent flight into horizontally strung mechanical, electrical transmission, or communication wires or cables. The WSPS™ is designed to reduce the possibility of wires entering into the cockpit area, reduce the possibility of flight control damage during a wire strike, and decrease the possibility of wires becoming entangled in the landing gear. 

It is the original helicopter wire cutting system with over 20,000 kits delivered worldwide. In actual cases, this system was effective against multiple wire strikes. The typical WSPS™ consists of an upper cutter/deflector, a windshield deflector and lower cutter/deflector. Each cutter is equipped with high tensile steel cutting blades.
