On September 2, 1998, about 1805 eastern daylight time, a Douglas DC-9-30, N927VJ, operated by US Airways as flight 1722, struck a refueling vehicle at Philadelphia International Airport, Philadelphia, Pennsylvania. The airplane received substantial damage. In addition, the fuel truck was damaged. There were no injuries to the certificated airline transport captain, co-pilot, 3 flight attendants, 81 passengers and refueling truck driver. Visual meteorological conditions prevailed for the international passenger flight that originated in Ottawa, Ontario, Canada, at 1641. Flight 1722 was operated on an instrument flight rules (IFR) flight plan under 14 CFR Part 121. Flight 1722 was about 1 hour 20 minutes behind schedule. The airplane landed on runway 27R, and exited the runway to the right at a high speed turnoff, K-4. The airplane continued with a right turn and passed through intersection OSCAR, headed straight toward the alleyway entrance between concourses A and B. Flight 1722 was cleared to change from tower frequency, to ground control, and then to US Airways ramp control. The flight was scheduled to arrive at gate B-8. In a written statement, the captain stated: "...I cleared the left side of the aircraft and proceeded toward the gate area. Just prior to entering the alleyway between Concourses A and B, my peripheral vision caught an object to our left. I immediately applied full brakes and immediately felt something contact the aircraft. I notified ramp control. Emergency equipment was called. It was determined that an evacuation was not necessary. There were no injuries to crew or passengers. Ultimately, the passengers were deplaned and transported to the terminal...." The operator of the refueling truck had recently transferred experienced drivers, including the accident driver, from other airports to increase the work force at Philadelphia. The accident driver first received 2 days of on the job training, which included riding with another driver. He also passed his Philadelphia Airport, vehicle airport operations area test, after which he was released for work. The accident occurred on his third day of work. He reported that he had serviced an airplane on the west side of concourse A. As he approached the alleyway entrance between concourses A and B, he observed a US Airways B737 to his right just outside of the outer service road. He further stated: "...I proceeded down the roadway [and] stopped before the stop [sign] next to 737. The 737 was to the right of the tanker. I look[ed] around and didn't see anything else coming or going. Seeing that the 737 wasn't going, I proceeded on looking to the left to see if any planes were taxiing out. I look[ed] to the right again, and I saw the DC-9 moving fast toward the tanker. I made a complete stop. When I saw the aircraft wasn't stopping I tried to kick it in reverse, but by the time I put it in reverse the aircraft [had] struck the lift on the right side of the truck." The investigation revealed that the outer service roadway crossed the alleyway entrance between concourses A and B. Printed on the roadway in white letters was, "STOP FOR AIRCRAFT." According to airport operations personnel, a driver would not be expected to stop if no aircraft were present. Vehicle drivers were instructed that airplanes have the right of way. Additionally, the investigation revealed that the US Airways B737 parked adjacent to concourse A would have obstructed the fuel truck driver's view of the approaching DC-9, and the flight crew's view of the fuel truck, until the fuel truck had passed from behind the airplane. Visibility to the right was further restricted for the fuel truck driver by refueling hoses located to the right of the cab. At the time of the accident, the fuel truck had driven 150 feet ahead of the STOP FOR AIRCRAFT sign. The front wheels of the fuel truck (empty weight 42,000 pounds) were displaced 2 feet laterally to the left. Skid marks were found from the left main landing gear of the DC-9, which measured 47 feet. The ramp was dry. US Airways submitted calculation which indicated the airplane was traveling at 14.48 knots when the skid was initiated. The fuel truck was a 10,000 gallon capacity truck, which was carrying about 5,000 gallons of Jet-A at the time of the accident.
