Ground handling at JFK

On 2 September 1998, the occurrence aircraft, inbound from Zurich, Switzerland, landed at JFK at 1716 and arrived at Gate 6 of Terminal 3, the Delta Airlines Terminal, at 1722. The aircraft was met at the gate by two security guards. One boarded the aircraft from the jetway as the main aircraft door was opened to disembark the passengers, the other was always present on the ramp during the off-loading of cargo and baggage. The security guards were contract personnel with an external security company; however, most of them had been with the company for several years. They were able to contact the base at the airport via a hand-held radio if they needed assistance or relief.

After the passengers disembarked, the on-board security guard inspected the overhead bins, the seats, and other areas of the aircraft to ensure that nothing had been left behind by anyone. A thorough physical search of the aircraft was completed.

Because there are limited gate facilities at JFK and Terminal 3, the aircraft had to be moved from the gate to a hard stand (parking area on the apron) and accessed by portable stairs; the aircraft remained there until a gate was available. The aircraft was towed to parking spot 74.

The security guard remained on board the aircraft until 2200, at which time another security guard relieved the first guard. During the first guard's shift, the aircraft cabin was groomed (cleaned) by approximately 20 cleaners during a period of 45 minutes. The guard was responsible for screening and monitoring personnel boarding the aircraft to perform the grooming. During the second guard's shift, the food for SR 111 was delivered. The second guard remained on board the aircraft as it was towed back to Gate 6 and deplaned when the crew arrived, at which time he stationed himself outside the aircraft door on the jetway until all the passengers had boarded SR 111. The aircraft pushed back from the gate at 2353, taxied from the terminal across the ramp, and exited the ramp via taxiway "KK".

Swissair security procedures at JFK

Any cash being transported on board would have been locked in a sales container and seals put on the locks by the cabin crew. The security personnel verified that the seals were secure. There was no official paperwork involved in this process.

The Port Authority Police were present for the loading and unloading of valuables. Outbound valuables were transported by armoured car from the cargo facility to the aircraft. The valuables were stored at the cargo facility in a bunker. The bunker, presided over by a security guard, has a watch room (a screened-in area, which is locked) and a vault for valuable items.

The security guard signed out valuables, which were loaded onto a transport vehicle. The transport vehicle was escorted by an armed, uniformed guard, and Port Authority Police, who stayed with the cargo until it was loaded.

For inbound flights, ramp security personnel conduct a physical check of the cargo bays and place tape seals over the doors. To do so, they get on top of high loader equipment and look around using a flashlight to ensure that the cargo bays are empty. They also physically check the cargo bays when the aircraft is returned to the gate.

Audits of the security practices at JFK were conducted semi-annually by Swissair quality assurance personnel from Zurich.

Aircraft maintenance at JFK

On the day of the occurrence, when HB-IWF arrived from Zurich, it had only one maintenance write up. The cabin crew complained that the rear lavatory had a bad smell. Maintenance personnel investigated and cleaned the lavatory. One of the maintenance workers noticed that one taxi light on the nose gear had a cracked lens, and it was changed. This maintenance action was not noted in the log book. The maintenance supervisor was informed of the light bulb change after the accident when he came into the office at 0700.
