Joe Sutter, who along with Jack Steiner, is father of the Boeing 737, believes the Bombardier CSeries' weak point is that its coach seating is 2x3 instead of 3x3 that is standard on all Boeing single-aisle aircraft.
Sutter, speaking in a Boeing briefing in advance of the Farnborough Air Show, said Bombardier will find it difficult to grow the aircraftbeyond the 149-seat CS300 in high density. Sutter likened the aircraft to the McDonnell Douglas MD-80, which also had 2x3 seating. While the MD-80/90/95 and predecessor DC-9 sold more than 2,000 airplanes over their lives, the 737 so far has sold more than 6,000.
Sutter, who is also considered the father of the 747, said he was paid $50 by Boeing for the patent on the 737.
Bombardier has been struggling to find a market for the CSeries. It has firm orders for 90 and options for an equal number going into the air show.
