Japanese authorities ordered Japan Airlines and ANA to inspect all Q400s after a pilot was forced to abort a flight recently prior to a take-off from Osaka.

Bombardier confirmed that reports indicated a propeller blade on a Pratt & Whitney Canada engine on a JAL Q400 was dented.

A spokesperson for the Canadian manufacturer emphasized that the inspection was not a "grounding order" and that the company was working with airline representatives and Japanese authorities.

It would not speculate on the cause of the damage until the engine is inspected fully.

"The damaged engine is en route to Canada," a Bombardier spokesperson said on Aug. 22. "It is expected to arrive shortly. Our engineers will be conducting a thorough investigation."
