The Final Communications: A Silence Descends
The moments leading up to the crash of Iran Aseman Airlines Flight 3704 are crucial for understanding the sequence of events. The flight's cruise phase, identified as IRC3704, was conducted at FL210 (Flight Level 21,000 feet) on airway W144. During this phase, no abnormal situation was reported by the crew, and the flight continued its communication on the Tehran Area Control Center (ACC) frequency. This indicates that up to a certain point, the flight was proceeding as expected, without any apparent technical malfunctions or distress signals.
The last known communication from the aircraft occurred at 06:00 UTC. At this time, Yasuj Tower communicated a corrected QNH (barometric pressure setting) of 1021, which was duly acknowledged by the captain. This exchange marked the latest communication between the flight crew and the airport tower. Shortly before this, the first officer had requested the latest weather information for the destination from Yasuj Tower, and then requested permission to leave FL210 to descend to FL170 from Tehran ACC. This request for descent suggests the aircraft was preparing for its approach into Yasuj. However, after the QNH acknowledgment, silence fell. The expected landing time of 09:50 local time in Yasuj never came to pass. The abrupt cessation of communication, following what seemed to be routine operational procedures, left investigators with a critical window of time to scrutinize, searching for clues that would explain the sudden and catastrophic end of Iran Aseman Airlines Flight 3704.
Unraveling the Causes: The "Human Factor"
Investigating an aviation accident is a complex process, often revealing a confluence of contributing factors rather than a single cause. In the case of Iran Aseman Airlines Flight 3704, the investigation concluded that while many chains of considered causes contributed to the incident, the "human factor" played the main role in the scenario's conclusion. This broad term encompasses a range of elements related to human performance, decision-making, training, and interaction with the aircraft and its environment. It suggests that actions or inactions by the flight crew, air traffic controllers, or maintenance personnel, or even systemic issues related to training and oversight, were critical in the tragic outcome.
While the provided data does not detail the specific aspects of the human factor identified, in aviation accident investigations, this often points to issues such as:
- Crew Resource Management (CRM): How effectively the flight crew communicated and coordinated their actions.
- Situational Awareness: The crew's perception and understanding of the aircraft's position, environment, and operational state.
- Decision-Making: Choices made by the crew, especially in challenging or unexpected circumstances.
- Training and Procedures: Adequacy of pilot training for specific conditions (e.g., mountainous terrain, icing) and adherence to standard operating procedures.
- Fatigue or Stress: The physical and mental state of the crew.
The conclusion that the "human factor" was paramount underscores the critical importance of robust training, continuous evaluation, and effective safety management systems within airlines. It also highlights the need for pilots to be equipped with the best possible tools and information to navigate complex environments, especially when operating in challenging weather conditions or over difficult terrain.
The Aircraft's Condition
It's important to note that the data indicates the aircraft's physical condition was within operational limits concerning its weight. According to the load sheet, the aircraft's takeoff weight was 20963 kg, which was within the specified operational limits for the aircraft type. This suggests that the crash was unlikely to have been caused by an overloaded condition. While the age of the aircraft fleet in Iran is a known concern (as discussed later), the immediate data available for Flight 3704 points away from a direct mechanical failure related to weight or balance as the primary cause, shifting the focus towards operational and human elements.
The Role of Air Traffic Control
The final communication with Yasuj Tower involved the acknowledgment of a corrected QNH. This interaction is standard procedure, but the timing and context of such communications are always scrutinized in accident investigations. While the data doesn't explicitly blame ATC, the "human factor" can also extend to ground personnel, including air traffic controllers. Their role in providing accurate information, maintaining clear communication, and ensuring safe separation and guidance is paramount. Any miscommunication, delayed information, or incorrect instructions could potentially contribute to a chain of events, especially in an environment where weather and terrain present significant challenges. The investigation into Iran Aseman Airlines Flight 3704 would have thoroughly examined all aspects of the interaction between the flight crew and ground control.
