Aviation and Parts repair

Our aerospace business consists of two major processes, manufacturing and repairing of aircraft parts. For manufacturing, we are involved in manufacturing parts for the aerospace, aircraft, and defense industries. This is mainly done at our Shiga and Himeji plants which are Nadcap accredited.

For repair, in 2011, Chiba plant commenced parts repair primarily for the heat treatment of aircraft engine cases and other special processes. Narita plant has been certified as an FAA repair station since 2012, and an EASA Maintenance Organisation since 2013. Our main repairs are for blades and vanes.

Chiba plant has been approved by the Japan Civil Aviation Bureau (JCAB) as an Approved Organization of repairing or remodeling equipment since 2014. Chiba is also a recognized FAA second fixed location and an EASA additional location for Narita plant.
