Lufthansa Technik has won two separate contracts to service auxiliary power units (APU) for the Airbus A350 fleets of South Korean carrier Asiana Airlines and flag carrier Vietnam Airlines.

The German MRO specialist says that Asiana signed a 10-year maintenance agreement for the long-haul jet’s Honeywell HGT1700 APU, which covers a planned fleet of 30 A350-900s.

Flight Fleets Analyzer shows the airline has six A350-900s already in service. The Star Alliance carrier in March switched its commitments for eight of the smaller A350-800 to the larger -900, leaving it with 15 -900s and nine -1000s on order.

Vietnam Airlines’ agreement with LHT covers 14 A350s, a dozend of which are in service.

The two deals are exclusive time-and-material-based contracts.

LHT says it is an official warranty station and partner of Honeywell for HGT1700 support.
