A problem with the delivery of engines by one of two suppliers has prompted Boeing Co. to delay deliveries of its new 787 Dreamliner until the first quarter of 2011.

Boeing on Friday said concerns about British engine manufacturer Rolls-Royce PLC’s ability to meet delivery schedules forced the Chicago-based airplane supplier to delay initial deliveries of the new commercial airliner.

Rolls-Royce said the delay was not related to the reported failure of an engine for the 787 Dreamliner in a recent test.

“We have been informed by Boeing that the currently planned dates for Trent 1000 engine deliveries will not support their latest flight test program requirements,” Rolls-Royce said in a statement Friday.

FlightGlobal, an aviation news Website, reported this week that a Trent 1000 engine suffered an “uncontained” failure  with debris breaking through the engine casing during a test on Aug. 2.

Rockwell Collins supplies the airplane’s flight deck, display system, crew alerting system, pilot controls, communication system, surveillance system, common data network and core network cabinet. The Cedar Rapids-based company also serves as systems integrator.

Boeing said the 787 Dreamliner delivery delay will not affect its financial outlook.

The 787 Dreamliner is made of many composite materials designed to make it lighter and more fuel-efficient than comparable planes used by the world’s airlines. Japan’s All Nippon Airways is the first customer slated to take delivery of the 787 Dreamliner.
