India Weighs Options for International Review of Flight Recorders
India’s Aircraft Accident Investigation Bureau (AAIB) is currently deliberating whether to send the flight data and cockpit voice recorders from the recent Air India crash overseas for analysis. The tragic incident occurred shortly after takeoff from Ahmedabad airport, resulting in the loss of at least 270 lives, primarily among passengers. While some reports suggested that the black boxes would be sent abroad, the Ministry of Civil Aviation clarified that no final decision has been reached. The AAIB will assess various factors before determining the best course of action for decoding the crucial data.
Investigation Progress and Black Box Recovery
Investigators have successfully retrieved both sets of Enhanced Airborne Flight Recorders (EAFRs) from the crash site of the Boeing 787. These critical devices, commonly referred to as black boxes, were located on June 13 and June 16. The aircraft is equipped with two sets of recorders to facilitate a comprehensive analysis of flight data and cockpit audio. The EAFRs meticulously track essential flight parameters, including gear and flap lever positions, thrust settings, engine performance, fuel flow, and fire handle activation. The information contained within these recorders is vital for reconstructing the final moments of the flight and understanding the cause of the tragic incident.
However, reports indicate that the recorders may have sustained significant damage due to the fire that engulfed the aircraft post-crash. This damage could complicate data extraction efforts in India, leading to speculation that the government might send the recorders to the United States for analysis. Captain Kishore Chinta, a former accident investigator with the AAIB, suggested that one set of recorders could be sent to the U.S. to compare data downloaded in India with that provided to the National Transportation Safety Board (NTSB). Despite the recent inauguration of the AAIB lab in Delhi, questions remain about its operational readiness for EAFR data downloads.
Air India’s Response and Safety Measures
In light of the crash, Air India’s chairman, N Chandrasekaran, provided insights into the aircraft’s engines, stating that one was new while the other was not scheduled for servicing until December. He emphasized that both engines had “clean” histories, suggesting they were not contributing factors to the accident. Following the incident, India’s aviation regulator mandated additional safety checks on Air India’s Boeing 787 fleet as a precautionary measure. Inspections have already been completed on 26 of the airline’s 33 Boeing 787-8 and 787-9 aircraft, all of which have been cleared for service.
In a proactive response to the crash, Air India announced a reduction in flights on 16 international routes and the suspension of services to three overseas destinations from June 21 to July 15. The airline explained that these reductions stem from a decision to implement enhanced pre-flight safety checks and to accommodate longer flight durations due to airspace closures in the Middle East. This announcement followed a previous statement indicating a temporary 15% reduction in flights operated with wide-body aircraft.
Future Steps and Ongoing Investigations
As the investigation continues, the AAIB is focused on determining the most effective method for analyzing the data from the black boxes. The decision on whether to send the recorders abroad will depend on a thorough assessment of technical, safety, and security factors. The findings from the analysis will be crucial in understanding the circumstances surrounding the crash and preventing future incidents.
The aviation community is closely monitoring the developments of this investigation, as the implications extend beyond Air India to the broader aviation industry. Ensuring the safety of air travel remains a top priority, and the outcomes of this investigation will likely influence future regulatory measures and safety protocols. As the AAIB works diligently to uncover the truth behind this tragic event, the focus remains on honoring the lives lost and improving aviation safety standards.
