Description:

CZ 06 413 EN

On 18 August 2006 Air Accidents Investigation Institute (AAII) was notified by the Czech Republic ATC and the Czech Air Force of an incident involving an aircraft Boeing B737, registered D-AHIF. The crew of D-AHIF was on flight HHI5753 from LTBJ to EDDW. Air traffic controller ACC Prague (NEU EC) was informed that flight HHI5753 was flying in FIR Bratislava without contact and the attempts to establish contact with HHI5753 crew failed. The aircraft HHI5753 entered FIR Prague at FL 380 over the point HDOPI without contact established, with the set code SSR 7600 and continued via UY444 to the point HDO. JAS 39 Gripen fighters of the Czech Air Force (QRA) scrambled against HHI5753. Contact with the crew was then established on an emergency frequency. The HHI5753 crew could not sent radio messages because of its VHF1 transmitter failure.
