The report suggests that the team tasked with probing into the incident is currently unable to present a definitive conclusion from the investigation into the crash of the ATR-72 plane operated by the Iran Aseman Airlines.
According to the report, the experts looking into the incident need more work and a more precise probe in order to arrive at a conclusion regarding what caused the crash.
Still, the following findings have been mentioned in the analysis section of the report:
– The pilot descended to 17,000 feet as demanded by the control tower, but further descent to 15,000 and 14,000 feet was against the regulations.
– The Pilot-In-Command (PIC) had medical restrictions for flight, which were not taken into account by the Aseman Airlines.
– Captain was not authorized to fly simultaneously with a co-pilot.
– The pilot should have flown at an altitude of 17,000 feet until reaching the airport
– The system giving alarms about frost on the wings and fuselage was not in ideal condition and should have been checked in the latest maintenance work. This negligence by the maintenance company cannot be condoned. If the anti-frost alarm system on the wings and fuselage had been active, it would have been possible to control the aircraft.
– The necessary technical work had not been carried out on the plane due to sanctions.
Still, the report is not final and the Iranian Civil Aviation Organization has not announced its final conclusion, yet.
