Honeywell signed an agreement for Hainan Airlines to use its GoDirect Maintenance Service, which uses connectivity and data analytics to improve maintenance operations and reduce equipment downtime.
China-based HNA's fleet of more than 50 Airbus A330s will be outfitted with Honeywell's Connected Auxiliary Power Unit (APU) predictive maintenance service to identify potential mechanical issues or failures before they happen. Honeywell will also outfit HNA's future fleet of more than 40 A330s with the same service.
The service works by using an existing data connection on the plane to download maintenance and fault data to predict impending hardware failures. Those failures are routinely the highest cause of APU interruptions. Fault data is then shared with Honeywell and analyzed before being presented to Hainan Airlines' maintenance team in a visual manner. The data identifies what maintenance actions are required to fix the APU and avoid an unscheduled maintenance event.
Honeywell completed a trial with Cathay Pacific to demonstrate how advanced data analytics can improve operational availability of its A330 fleet. Using existing datalinks, successful analysis of data from the equipment showed a 35% reduction in operational disruptions with a false positive rate of less than 1%. Honeywell says the system could save the airline several hundred thousand dollars in operations and maintenance costs on a single aircraft system.
