The NTSB's narrative final · quoted from the NTSB record

On April 28, 2016, about 2252 pacific daylight time, SkyWest Airlines flight 5260, N961SW, a Canadair CRJ-200, was struck after being pushed back from the gate by an airplane that was being towed by maintenance personnel at San Francisco International Airport (KSFO), San Francisco, California.  There were no injuries and both airplanes received substantial damage. The regularly scheduled domestic passenger flight was operating under the provisions of 14 Code of Federal Regulations Part 121 from KSFO to Meadows Field Airport (KBFL), Bakersfield, California. After having been pushed back from the gate, N961SW was awaiting taxi clearance with engines operating and the parking brake set when it was struck by the Boeing 777 that was being reposition under tow. The tug driver that was pushing the Boeing 777indicated that he saw wing walkers on both sides and began to push back.  He stated that he never saw any signal from the wing walker's signal wands indicating to stop. The left wing walker stated that the tow driver started pushing the Boeing 777 in reverse before asking if he and the other walkers were ready stating, that the airplane "was halfway out of the gate before I could react." He stated that, after the airplane entered the roadway, he notice that the tug driver was not slowing down as he approached N961SW.  The left wing walk made an "X" with his signal wands and then started jumping up and down and moving to better location to be seen.  The Boeing 777's lower left fuselage contacted the right stabilizer of N961SW resulting in substantial damage to the stabilizer and right elevator.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number DCA16CA139.
