P&WC increases time between overhauls for PW210 family

February 22, 2016  By Pratt & Whitney Canada

Pratt & Whitney Canada has announced that it has extended the basic time between overhaul (TBO) for its PW210 turboshaft engines from 3,500 to 4,000 hours. This will increase time-on-wing and reduce maintenance costs by over 10 percent for operators. The extension applies to all PW210 engines currently in service and those to be produced in the future.

In an effort to offer greater value to its helicopter customers, P&WC is also deploying additional commercial initiatives that will reduce direct maintenance costs (DMC) by up to 15 percent for operators with very short missions. These initiatives will enable further savings under P&WC’s Eagle Service PlanĀ® (ESP) program and Fleet Management ProgramĀ® (FMP) solution.

This is just the latest in P&WC’s ongoing efforts to support its customers with solutions that lower DMC and deliver bottom-line value. “We understand the importance of reducing costs for our customers,” said Irene Makris, Vice President, Marketing, P&WC.

“The PW210 has been designed for low maintenance and maximum availability. In addition to the 4,000-hour TBO, its benefits include no scheduled oil changes, no scheduled borescope or vibration checks and an easily accessible and integrated nozzle for compressor wash, all of which make it simpler to maintain and reduce maintenance expenses.”

The PW210 is P&WC’s latest family of helicopter engines and is fast proving itself to be an industry leader. Its strong performance and reliability are among the reasons P&WC is able to extend the TBO. They are also why more and more operators worldwide are choosing this engine in fields of all kinds, including emergency medical services, journalistic missions, VIP transport, power line inspections and oil and gas industry applications.


It has already made successful entries into service as the engine of choice for Finmeccanica’s AW169 in December 2015 and for the Sikorsky S-76D™ in January 2014. Raising the industry bar for a clean-sheet engine design, it has flawlessly accumulated close to 10,000 flight hours on the S-76D helicopter. National Helicopter Services Limited (NHSL), based in Trinidad and Tobago, operates five Sikorsky S-76D aircraft powered by PW210S engines and is the fleet leader. It has accumulated close to 5,000 flight hours since entering into service. Entries into service will accelerate in 2016, with a number of operators set to begin flying PW210-powered helicopters this year. “We continue to find homes for the PW210 with new customers and platforms and to cross new boundaries as it establishes its pedigree around the world,” noted Makris.

The PW210 is shaping a new generation of intermediate- and medium-class twin-engine helicopters, setting exceptional standards in fuel efficiency, power-to-weight ratio and operating economics. With every aspect of the engine designed with the customer in mind, the PW210 delivers a wide range of power options. It is elegantly simple in concept, with only five major rotating components.

The PW210 engine also doubles as an auxiliary power unit (APU), powering electrical, heating and cooling systems while the aircraft is on the ground, with a locked or disengaged main rotor – saving the cost and weight of a third engine.

The engine features dual channel full authority digital engine control (FADEC) that raises the bar for ease of pilot operation and maintenance diagnostics. Engine information can be downloaded from the FADEC and engine memory storage device to P&WC’s standard ground-station software, a powerful tool linked to P&WC’s online interactive publications and diagnostic tool, Spotlight™. Spotlight provides simple, guided troubleshooting through an interactive interface integrated with P&WC’s maintenance manuals.
