Wall Street analysts queried by The New York Times on Monday predicted Boeing will soon announce another delay in the first delivery of its trouble-plagued 787 Dreamliner jet.
The company is still working to resolve issues with an electrical panel in a test plane that sparked a fire two weeks ago as the aircraft was landing at Laredo, Texas.
Boeing said it will make minor changes to the electrical panel itself where the fire started. The company believes that a small foreign object caused a short circuit that triggered the fire.
The company is also expected to make modifications to the aircraft software to ensure that the plane can continue to operate safely after a power failure such as the one over Texas.
The test plane landed successfully, but much of the instrument panel went blank and an alternate power source, a wind-driven turbine, deployed from the side of the aircraft.
Boeing has halted test flying by the six-plane 787 fleet while it crafts a cure for the problem.
The official schedule now calls for first delivery in February 2011, but analysts believe that will erode further.
