Simplex Aerospace has received FAA STC for a hover refill pump storage latching system, called the Aft Hook™. The Aft Hook™ allows firefighting helicopter operators to store the 5″ hover pump during flight and deploy the pump upon arrival at a water fill source. When installed on a Simplex Fire Attack system equipped helicopter, the Aft Hook™ allows operators to transport passengers while the hover pump is installed. The Aft Hook™ will make the Simplex Fire Attack system the only tank system available with this transport category option. The new Aft Hook™, currently STC’d for medium Bell helicopters, is used in conjunction with the Simplex Aerospace model 304 Fire Attack system for medium Bell helicopters.
