Honeywell has signed an agreement for Hainan Airlines to become the first airline in the world to use its GoDirect maintenance service programme.
This uses connectivity and data analytics to improve maintenance and reduce equipment downtime, and is a demonstration of how the connected aircraft and e-Enablement is changing aircraft operations.
HNA’s current fleet of more than 50 Airbus A330s will be outfitted with Honeywell’s Connected Auxiliary Power Unit (APU) predictive maintenance service to improve fleet availability.
The goal is 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, so totaling more than 90 A330s using GoDirect.
The Connected APU service works by using an existing data connection on the aircraft to download APU maintenance and fault data to predict impending hardware failures.
Those failures are routinely the highest cause of APU interruptions. The fault data is then shared with Honeywell and analysed before being presented back to Hainan Airlines’ maintenance team in an easy-to-understand, visual manner.
The data identify what maintenance actions are required to fix the APU and avoid an unscheduled maintenance event.
Brian Davis, Vice President, Airlines, Asia Pacific, Honeywell Aerospace, said: “The business and passenger impact of Honeywell’s Connected APU service for Hainan Airlines is significant.
“Not only will the airline receive better and more predictive maintenance services that will reduce mechanical delays and cancellations, it will also improve first-time fix rate, reduce false removals and improve the passenger experience.
“This is a monumental agreement not only for Honeywell and Hainan Airlines, but for the aerospace industry as it undergoes a digital transformation that’s opening up new forms of data-sharing and changing the industry as we know it.”
Xie Haoming, Chairman of Hainan Airlines, said: “We are committed to providing our customers with our unique five-star in-flight experience, whether that’s the ‘eastern-style’ services available or an on-time departure to one of our global locations.
“Honeywell’s GoDirect Maintenance Service helps us maintain this commitment by reducing APU downtime, keeping our planes in the air more often to do what we need them to do, which is getting passengers to their destinations safely and on time.”
Honeywell, with more than 80 product lines and nose-to-tail technologies, is using its expertise to change the concept of airplane maintenance.
As part of its suite of Connected Aircraft Services, Honeywell’s GoDirect Maintenance Services programme will keep airline maintenance groups a step ahead of any potential issues, before they ground a plane, thereby reducing operational disruptions and costs.
Existing trials of Honeywell’s predictive maintenance services resulted in a 35 percent reduction in inoperative equipment, and a significant reduction in operational disruptions with a false positive rate of less than one percent.
