The FAA has said that it moved to order U.S. airlines to stop flying 787s after the All Nippon incident because it occurred while an airplane was in flight.
The AP reported that Tonomoto predicted All Nippon would lose 3 percent of its anticipated revenues in the current fiscal year if the 787 is not cleared to resume flying.
Neither the FAA or its counterpart agencies in other countries have specified when the 787 will be allowed to fly again.
The National Transportation Safety Board (NTSB) says that the battery on a 787 that caught fire at Boston's Logan International Airport exhibited signs of accelerated temperature increases known as "thermal runaway" and short-circuiting.
The NTSB is conducting its own review of the 787.
