A third NEO engine will begin high-pressure spool tests next month, while a fourth PW1100G has begun endurance testing for certification at Pratt's Manitoba icing facility. The first four engines are expected to collectively amass 1,000 test hours in the run-up to full certification testing, which is due to get underway in “two to three months,” Saia says.

Four production PW1500Gs have meanwhile been delivered to Bombardier, the first two of which are mounted on the initial CSeries aircraft that is expected to be powered-up shortly. The Canadian airliner is slated to make its first flight in June. A fifth engine is in the test cell at Pratt's Mirabel production facility where another four engines are now in final assembly.

Test work on the PW1200G for the MRJ is also advancing and is now at the halfway point, Saia says: “We completed all block testing and fully validated the design, and its readiness for certification.” The company is now assembling the fifth engine.
