G-AGRH "Zephyr" was an Avro Super Trader IV cargo aircraft which crashed on Mount Süphan, Turkey on 23 April, 1959. The Super Trader IV was a modified Avro Tudor IV which had been fitted with an aft cargo door and was flown unpressurised.

Loss

G-AGRH departed Ankara for a flight to Bahrain. At 08:14 the aircraft passed Gemerek at FL115 and Elazig at 08:59 (at FL135). The last position report received was when over Mus at 09:26. The aircraft had crashed, and was found after 6 days on Mount Süphan.

Causes

It was concluded that the aircraft, which had been flying on instruments, drifted north of its normal track because of strong winds and crashed into the mountain. Contributing factors were that winds were stronger than forecast; an accurate bearing could not be obtained at Mus, and Van had not been checked; sub-normal temperatures would result in a high indicated altimeter reading; calculations on the flight and contacts with beacons were not coordinated and controlled.
