The FAA and Boeing could not immediately be reached for comment, and a document cited by the two sources was not available on the FAA’s website Saturday.
The company is on track to deliver 10 to 12 of the 787-9, which is a larger version of the 787-8, this year, according to All Things 787.
The airplane is assembled in Everett and North Charleston, South Carolina.
UPDATE: Boeing has confirmed that it received FAA approval. However, a spokesman declined to comment on when first delivery of a 787-9 with GE engines would happen.
