Japan Airlines subsidiary Japan Transocean Air has signed a long-term engine maintenance deal with ST Engineering’s aerospace unit.

The 15-year contract will see ST Engineering provide maintenance-by-the-hour support for the airline’s Boeing 737NG fleet. It includes off-wing maintenance support, on-wing services, as well as technical support, and will be done at ST Engineering’s engine facilities in Singapore.

Japan Transocean Air president Noriyuki Aoki says the agreement builds on the longstanding partnership between the Japan Airlines Group and ST Engineering.

“We believe this customised … programme will bring even greater value-add to our business through stability in engine operations in order to provide the highest possible standards in reliability and on-time performance for our customers. Furthermore, it provides us leverage through maintenance cost optimisation and cost control benefits,” he adds.

Japan Airlines Group, which already has several long-term maintenance contracts with ST Engineering, owns 70.1% of Japan Transocean Air. Cirium fleets data indicates the latter carrier operates 12 737-800s, all of them powered by CFM56-7B engines.
