Late Engine Issue May Cause A320neo First Flight Delay

Airbus and Pratt & Whitney are believed to be tackling a late-developing certification issue with the PW1100G geared turbofan in an attempt to stave off the looming threat of a delay to the first flight of the re-engined A320neo.

The aircraft manufacturer, which declines to comment, has targeted September for first flight of the A320neo with the Pratt engine but, according to industry sources, may be forced to delay this because of unidentified concerns related to the PW1100G. Airbus had hoped to fly the test aircraft, MSN6101, as early as Sept. 5. However the modified A320neo, which was pictured taxiing under its own power at Toulouse on Sept. 1, remains on the ground.
