Hewitt sets the aviation industry benchmark for high quality fueling hose assemblies, couplings, nozzles and accessories.
So, aircraft fueling must be conducted with the highest standards of safety, which are described in detail in the National Fire Protection Association’s NFPA 407 Standard for Aircraft Fuel Servicing. The standard states that all fuel servicing equipment must be maintained in good working condition. Daily inspection is advised especially for the fueling hose, the most important component of the fuel system as noted by Aviation Pros.
If the aviation hose is in constant use and not removed from service, it can last anywhere from six months at major airports to 10 years at the smallest facilities. Users should conduct at least monthly inspections of hose assemblies for wear, as well as any movement of the fittings on the end of the hoses. In addition, pressure testing of an assembly to a minimum of working pressure should be conducted at least every six months. Hewitt provides guidance for aviation fueling safety and maintenance, best practices for hose inspections, fuel flushing recommended practices and identifying hose ID measurements correctly.
