PARIS/MONTREAL, Sept 6 (Reuters) - Further delays in deliveries of the latest jet engine from Pratt & Whitney underline the challenges of speeding up manufacturing for multiple planemakers as well as pressure on an already taut supply chain, industry sources said.

Canada's Bombardier said it was cutting forecasts for CSeries jet deliveries because of delays in getting engines from Pratt & Whitney, one of a handful of engine makers whose efficient new designs have triggered a boom in aircraft sales.

Pratt & Whitney did not say what had caused the delays, but suggested it was grappling with problems at its own suppliers.

"In terms of production, we've made significant headway in the supply chain, but there is some pressure on new engine deliveries for this year," a spokeswoman said in a statement.

Three industry sources said the U.S. engine maker also faces challenges in bedding down the manufacturing techniques for the engines' novel "hybrid-metallic" fan blades, the world's first to be made mainly from aluminium alloy.   Continuación...
