Pratt & Whitney Canada has signed a 15-year maintenance agreement with Singapore Airlines for the upkeep of 34 APS5000 auxiliary power units (APUs). These APUs support the airline’s fleet of Boeing 787 Dreamliner aircraft.
According to Anthony Rossi, Vice President of Customer Service at Pratt & Whitney Canada, the agreement provides tailored maintenance solutions that will keep the APS5000 units operating at peak performance. He noted that the APS5000 is the industry’s first all-electric APU and was developed exclusively for the Boeing 787 Dreamliner. Its design offers improved fuel efficiency, lower emissions, and enhanced maintainability, contributing to the airline’s strong operational reliability.
Rossi added that this contract would help ensure the APUs continue to meet the manufacturer’s original equipment standards. This, in turn, will support Singapore Airlines in maintaining its high levels of dispatch reliability and in focusing on providing an excellent passenger experience.
The APS5000 is recognised as the quietest APU in its class and has the lowest emissions in the industry. It produces 450kVA of electrical power at sea level and can start and operate at altitudes of up to 43,100 feet. Over 1,400 APS5000 units have been produced, and the global fleet has accumulated nearly 16 million flight hours.
Pratt & Whitney Canada’s maintenance programmes for its APU portfolio are designed to provide flexibility and predictable cost structures while maximising operational performance and extending maintenance intervals. The agreement with Singapore Airlines reinforces the company’s commitment to supporting customers with advanced and reliable APU technology that underpins the efficiency of modern long-haul fleets.
