Another word for safety is maintenance. But proper aircraft maintenance is necessary not only because human lives are at stake. With environmental problems an increasingly serious challenge for the entire human race, it is also important to use materials for longer periods of time. Nippi's maintenance expertise has been proven on over 13,000 aircraft of more than 100 models. We serve for the Japan Defense Agency and the Japan coast guard, the U.S. Navy, and many international aircraft manufacturers.
