The black boxes of the Iranian airliner which crashed on earlier this
month killing all 32 aboard, had technical problems and are missing
information that should have been recorded, the official IRNA agency
Vali Azarvach, the deputy heading the commission into the May 17
crash of the Russian-built Yak-40 plane, was quoted by IRNA as saying
"we do not know why the electric current supplying the black boxes
"The idea emerging from the study of these boxes is not good," he
said without elaborating.
He said that "one of the boxes is completely blank and neither radio
conversations nor the conditions of the accident have been recorded."
"The flight conditions do not correspond to the standards of the
international civil aviation organisation.
"The plane's pilot had never made this journey, and he had not been
given the information necessary for the flight, in particular the
metereological conditions," he said.
The deputy said that the commission "will continue its inquiry into
the crash seriously and carefully."
The two black boxes were sent to Russia last week to be examined.
On Sunday, Iran's civil aviation authorities said that the Armenian
pilot was to blame for the crash.
"The investigation, carried out by a team of Iranian experts sent to
Moscow, shows human error -- that of the pilot -- is the cause of the
accident but the final results of the inquiry will be made public
soon," said civil air chief Behzad Mazaheri, quoted by IRNA.
He said Russian experts helped with the examination of the
flight-data recorders or black boxes.
Transport Minister Rahman Dadman, two of his deputies, seven MPs and
some 20 other people perished on the flight, which crashed shortly
after the pilot radioed to say he would try an emergency landing in
the northern city of Sari.
The pilot of the plane, which had been rented from Armenia by Faraz-e
Qeshm airlines, was an Armenian national, as were the co-pilot and
three crew members.
The wreckage of the plane was found some 20 kilometers (12 miles)
south of Sari.
Aviation authorities recently announced plans to outlaw foreign
pilots on Iranian planes, although Iran leases many aircraft from
other nations to fill the gaps in its air transport system.
