The emergency exercise involved a Thai Airbus A340-500 which was parked at aircraft stand A6 at the airport. The Bureau of Aeronautical Meteorology gave an announcement for adverse weather conditions. The Electrical Field Mill was more than 2,000 volts per meter which meant a danger from lightning strikes. The Airside Operation Control Center (AOCC) then immediately gave a “lightning warning” to all staff at the airport by telephone and trunk radio. A “Follow Me” vehicle was also dispatched to broadcast a warning to all staff working in the field. Unfortunately, due to communication problems, staff at parking bay A6 continued to service the aircraft unaware of a potential danger.
At 10.20 a.m. the aircraft is struck by lightning. Seven minutes later, the supervisor discovers that one of his crew is down. The Ground Operation Control Center (GOCC) is quickly notified of this tragedy. The GOCC immediately notifies the Suvarnabhumi Medical Department. At 10.34 a.m., an ambulance, that was on standby on Concourse D, is dispatched with a full medical crew. A doctor briefly checks out the victim and then he is loaded onto a stretcher and the ambulance quickly leaves for the nearest hospital.
At 10.35 a.m., another victim is found by the supervisor who immediately raises the alarm. GOCC is once again informed. They then contact Suvarnabhumi Medical Department who are told that there is a second victim. At 10.40 a.m., a second ambulance is dispatched from Smitivej Hospital to pick up the victim at parking bay A6. At 11 a.m., the weather situation returns to normal. The Bureau of Aeronautical Meteorology revokes the adverse weather warning. The AOCC receives the message and relays a “Normal Weather” situation report to everyone.
