An Iran Air Boeing 727 accident occurred on June 9, 1996 near Rasht during a training flight. In the crash of the Boeing 727-286Adv , four out of seven occupants were killed.

machine

The aircraft involved in the accident was a Boeing 727-286Adv., Which was 21 years and 1 month old at the time of the accident. The machine was the work of Boeing on the Boeing Field in the state of Washington assembled and completed on 29 April 1975 its first flight before it was delivered new on May 8 of that year to the Iran Air. In the 1970s, the state airline of Iran, which was ruled by Shah Mohammad Reza Pahlavi at the time , was frequently supplied with airplanes; deliveries of Boeing planes to Iran were only stopped after the Islamic Revolution . The aircraft had the factory number 21079, it was the 1131. Boeing 727 from ongoing production. The machine was certified with the aircraft registration EP-IRU . The three - engine narrow -body aircraft was equipped with three Pratt & Whitney JT8D-15 engines. By the time of the accident, the machine had completed a total of 38,678 operating hours.

Inmates and flight plan

On June 9, 1996, there was only a seven-person crew on board the machine. The aircraft was flown from Tehran's Mehrabad Airport to Rasht Airport , where training approaches were to be carried out.

the accident

During flight training, repeated touch-and-go maneuvers were flown with the machine. After the fifteenth maneuver of this type, the pilots landed the machine with the landing gear retracted because they had forgotten to extend it. The machine dragged across the roadway on its stomach over a length of 2100 m, after which the pilots took off the heavily damaged aircraft again. Meanwhile, a fire had developed in the rear part of the trunk. The plane flew holding patterns over the airport. The landing gear was extended manually and air traffic control gave clearance to land on runway 09. The fire was meanwhile spreading and damaging the flight systems. The captain found it difficult to keep the engine under control. Five kilometers west of the airport, the left wing grazed the ground, whereupon the plane fell into a rice field and broke apart. Four of the seven crew members were killed.

root cause

A number of factors were cited as the causes of the accident:

  • The flight crew did not react to the acoustic warning signal that warned them of touching down with the landing gear retracted
  • the crew did not properly go through the landing checklist
  • inadequate crew resource management (CRM)
  • the pilot in charge had forgotten to extend the landing gear
  • the grinding of the machine on the hull over a period of 30 seconds and a distance of 2100 meters of track length
  • the continuation of the flight for a period of 9 minutes and 30 seconds regardless of the development of fire and smoke on board
  • the eventual failure of the flight control systems
