Core Viewpoint - The crash of Air India flight AI171, a Boeing 787, raises significant concerns regarding the aircraft's takeoff process and the potential factors leading to its failure shortly after departure [1][2][4]. Group 1: Incident Overview - AI171 was involved in a fatal crash shortly after takeoff on June 12, marking the first accident for the Boeing 787, known for its advanced technology [2][3]. - The flight was scheduled from Ahmedabad to London, and prior to the incident, the aircraft had completed a flight from New Delhi to Ahmedabad without reported issues [2][3]. - Weather conditions were favorable at the time of the incident, with good visibility and normal wind speeds, although the temperature was high at 37 degrees Celsius [2]. Group 2: Takeoff Process - The takeoff process involved inputting load information into the aircraft's computer system, which is designed to provide necessary takeoff data [3]. - The aircraft began its takeoff roll at 13:38 local time, reaching decision speed before attempting to lift off [3]. - Unusually, the landing gear was not retracted after takeoff, and the aircraft failed to gain sufficient power, leading to a crash within a minute of departure [3][4]. Group 3: Technical Analysis - Data indicated that AI171 began descending at a rate of -475 feet per minute after reaching an altitude of 625 feet [4]. - The sudden loss of power shortly after takeoff raised questions about potential causes, including possible mechanical failures or incorrect operational procedures [5][6]. - The possibility of a bird strike was considered but deemed unlikely due to the absence of engine anomalies such as surging or smoke [6]. Group 4: Pilot Response and Emergency Protocols - The pilots reportedly declared a "Mayday" shortly after takeoff, indicating a critical emergency situation [5]. - The time available for the pilots to respond to the emergency was extremely limited, suggesting that the aircraft's performance deteriorated rapidly [5][7]. - The failure to retract the landing gear may indicate that the pilots were preoccupied with addressing other urgent issues [7]. Group 5: Industry Implications - The incident highlights the importance of human-machine interaction in aviation safety, emphasizing the need for effective communication and coordination between pilots and ground staff [8]. - The aviation industry continuously learns from accidents to improve safety protocols, with the black boxes from the incident expected to provide further insights into the crash [8].
