A aeronave foi forçada a regressar a Lisboa, de onde tinha partido às 10.36 horas, já com um atraso de 36 minutos, por se considerar que não estavam reunidas as condições de segurança para seguir para Angola.
Rui Oliveira, porta-voz da ANA, explicou ao JN que a aterragem decorreu "normalmente, sem qualquer problema".
A ANA ativou o nível de alerta de prevenção local, o mais baixo da escala, e o habitual neste tipo de incidente.
De acordo com o protocolo, qualquer avaria ao nível das comunicações obriga a que os aviões ou regressem ao aeroporto de origem ou aterrem no aeroporto mais próximo.
A TAAG Angola Airlines Boeing 777-300, registration D2-TEG performing flight DT-651 from Lisbon (Portugal) to Luanda (Angola) with 197 passengers, was climbing out of Lisbon's runway 03, when departure control began to complain about somebody blocking the frequency, the aircraft could be heard calling Lisbon on a wrong frequency and began to squawk loss of communication. Approach control called the aircraft repeatedly suggesting to turn off the other radio and change to the correct frequency. Communication was eventually re-established with approach control about 5 minutes after the onset of trouble, the aircraft had levelled off at FL080 in the meantime, communication was lost again and the aircraft's radio began to block frequencies again. The crew decided to return to Lisbon for a safe landing on runway 03 about 70 minutes after departure.
The aircraft squawked loss of communication until after landing, normal operation of the airport as well as routine operation of Lisbon approach resumed however about 10 minutes after the second loss of communication. The aircraft was not heard again on any of Lisbon's official frequencies.
