Air China has signed an agreement with Honeywell Aerospace for repair and maintenance services for auxiliary power units (APUs) on some of its widebody aircraft.

Under the agreement, Honeywell will repair and maintain 311-350 APUs fitted on 53 new and existing A330 and six A340 aircraft.

“This agreement underscores the long-term relationship between Honeywell and Air China, and enables the airline to maintain high reliability and optimal efficiencies that ultimately lower the total cost of ownership,” says Briand Greer, president, Asia Pacific, Honeywell Aerospace.

Honeywell will also provide Air China with customised service and maintenance solutions, which it says will help the carrier to better manage its predicted maintenance spending.
