Lawyers for Saudi Arabian Airlines have testified to the Indian Court of Inquiry that the Kazakhstan Airlines Ilyushin Il-76 crew descended through their cleared altitude, causing the 12 November 1996 fatal collision with the Saudi Boeing 747-100 near New Delhi, India.
Saudi Arabian claims that its crew carried out air traffic control (ATC) instructions to stop their aircraft's climb at 14,000ft (4,300m). Lawyers for the Kazakh airline claim that the error was caused by ATC because it allegedly given too little warning of the position of the 747.
Following the 17 April Merpati Nusantara Airlines British Aerospace ATP fatal accident, Indonesia's air-transport director has grounded Merpati's four ATPs "-until there is further information on their airworthiness". Aero International (Regional) confirms three were already grounded because of a lack of spares.
