WASHINGTON — Federal investigators say they have interviewed the captain of an Air Canada jet that descended toward a taxiway holding four other planes rather than the assigned runway and narrowly avoided disaster at San Francisco International Airport.

The National Transportation Safety Board said it would also talk to the co-pilot Tuesday and finish talking to air traffic controllers by Wednesday.

The NTSB said the Air Canada Airbus A320 was cleared to land on runway 28R but instead lined up its approach for a parallel taxiway, which four other airliners were using to get in position to take off.

The NTSB said the Air Canada jet descended to less than 100 feet above the ground and flew over another plane before aborting the landing on July 7.

Air Canada declined to comment, citing the investigation.

The Air Canada jet, with 140 people on board, was arriving from Toronto. The NTSB statement adds details to the first official description of the close call, a summary released last week by Canadian safety authorities.

Also Monday, California Insurance Commissioner Dave Jones, who was a passenger aboard the flight, released a letter to Air Canada in which he requested that the airline keep passengers informed of the results of any investigation. He said passengers were not told what was happening, and instead, the pilot "made a nonchalant announcement that he had to go around due to traffic at the airport."

Canada's Transportation Safety Board has given the flight data recorder, one of the so-called black boxes from the Air Canada plane, to the NTSB, which is leading the investigation.

The NTSB said it has security-camera video of the late-night incident and will release it in the coming months.
