Probable Cause and Findings

The failure of the flight crew and the tug driver to verify that the aircraft was properly configured for pushback. Factors in the accident were the left wing walker's failure to notify the tug driver of his observations that the jet bridge was still in contact with the aircraft, and, self induced pressure on the part of the captain created by a chain of circumstances surrounding the numerous delays.

Analysis

On July 24, 1999, at 0805 hours mountain standard time, America West Flight 2082, a Boeing 757-2G7, N910AW, contacted the jet way during pushback in Phoenix, Arizona. The aircraft sustained substantial damage; however, none of the 190 passengers or 6 crewmembers aboard were injured. The aircraft was being operated as a scheduled domestic passenger flight by America West Airlines, Inc., under 14 CFR Part 121 when the accident occurred. The flight was originating from Phoenix Sky Harbor Airport as a nonstop flight to San Diego, California. Visual meteorological conditions prevailed at the time and an IFR flight plan was filed.

In his written statements, the captain noted that there were repeated delays for the 0732 scheduled departure time. The first delay occurred in dispatch when the printers were not working and no flight release was available. He then proceeded to the gate to drop off his bags and found that the airplane was still in the maintenance hangar. The captain then went back to dispatch, where the printers were still not working. He walked back to the gate, where the aircraft was finally towed into position at 0720. After dropping off his bags, he went back to dispatch where a release was finally produced. The aircraft was finally loaded with passengers and was ready for pushback by 0800. A few minutes later, a mechanic boarded the aircraft and told the captain that a serviceable hydraulic actuator on his aircraft needed to be "swapped out" with the same part from another aircraft. The captain said at this point his blood pressure "was up to the stroke level," and he was very distracted by the thought of another delay. About a minute later, another mechanic entered the cockpit and told the captain that maintenance control had thought better of the swap idea and they were not going to exchange parts. The mechanic ended the conversation with, "we are all closed up and ready to go."

The captain said he believed the mechanic's statement meant that the aircraft doors were secured for departure. In his statement, the mechanic said he meant that the exterior access panels on the aircraft were closed. The captain further said that he was unaware that the gate agent and a customer service representative were onboard the aircraft trying to sort out an oversold situation, and that the L2 door was still open with the jet bridge still connected to the aircraft.

As the captain made a public address (PA) departure announcement to the passengers, the first officer called for pushback and advised "You are cleared to push, tail south on Lima." The captain then asked the tug driver "Are you guys ready to go?" According to the captain, the tug driver replied with the "all doors and access panels are closed" speech. According to the tug driver, he replied that all service doors and cargo doors, except for the jet bridge, were secured and locked. The captain then advised the tug driver, "Brakes released, you are cleared to push, tail south, on Lima." The tug operator repeated the order and signaled the wing walkers that he was preparing to push back. As the push began, the sounds of the aircraft contacting the jet bridge were heard by the flight crew. The pushback damaged the jet way, the aircraft skin, the L-2 aircraft door, and caused the uncommanded deployment of the L-2 evacuation slide.

After the accident, the right wing walker stated that he had not given the tug driver the "all clear" signal that is required prior to pushback by company directive. The left wing walker said that he assumed that something was wrong with the jet bridge since the captain had said it was okay to push back. He raised his wand to show the driver that the ramp was clear.

Although the door light on the overhead panel and the engine indicating and crew alerting system (EICAS) screen were both illuminated, showing that the L-2 door was open, neither the captain nor first officer noticed them prior to push.

The team lead that was responsible for the gate operation was still in the jet bridge doorway with a gate agent while the gate agent supervisor was trying to resolve an "oversold" problem with two passengers. The supervisor was not able to seat the passengers and they were sent back up the jet bridge. The team lead and gate agent were waiting for the supervisor to get off the aircraft when the pushback began. The jet bridge is normally retracted by the gate agent after the door is secured, but may be secured by other trained airline or contract personnel.
