Description:

CZ 06 105 EN

On 18 April 2006 the Czech Republic ATC notified Czech Republic Air Accident Investigation Institute (AAII) of an incident involving a Boeing 777 of Viet Nam Airlines. The air crew on HVN 545 flight from Hanoi Noi-Ba (VVNB) airport to Franfurt (EDDF) airport entered FIR Prague over the PADKA at FL 360 without establishing contact and continued to the RAPET. The ACC Prague controller made all the prescribed attempts to establish contact with HVN 545 crew. JAS 39 Gripen fighters of the Czech Air Force (QRA) scrambled to intercept the airplane upon which contact with the crew was established on the emergency frequency. The crew got the instruction to transfer to the appropriate sector frequency and continued on the scheduled route.
