An existing customer of the Bombardier CSeries airliner has added a further three aircraft to its existing order, pushing the company’s backlog through 200 aircraft.

The customer, who has “requested to remain unidentified at this time,” according to Bombardier (Chalet CD61), ordered an extra three CS300 aircraft worth $228 million, the company announced on February 10, on the eve of the Singapore Airshow.

“As of today, we have more than 10 aircraft in various stages of testing and production, and together with the key components being manufactured at our partner sites for aircraft that follow, the CSeries aircraft program is progressing steadily,” said Mike Arcamone, president of Bombardier Commercial Aircraft.

The company says the aircraft is generating increased interest from customers as the flight test program ramps up. Two prototypes, FTV1 and FTV2, are flying regularly, and the third prototype, FTV3, was handed to the flight test team in early February. Bombardier says it plans to begin flight tests of that aircraft shortly.

Major customers for the new airline include Lufthansa, Republic Airways, Gulf Air, Korean Air and various leasing companies.

Bombardier also announced that Abu Dhabi-based Falcon Aviation Services has ordered a pair of Q400 regional airliners, in a deal worth $61 million.

Falcon Aviation, which is based at the city’s Al Bateen Executive Airport, is a new customer for the Q400. The company is better known for operating a fleet of business jets as well as light and medium helicopters, which are used to support the oil and gas industry in the region.

Captain Mahmoud Ismael, CCO at Falcon Aviation Services, says, “With this acquisition, we are diversifying our business model and offering a broader range of services to our clients.”

Falcon also conducts search and rescue, aircraft MRO and consulting operations.
