Boeing(US:BA) Guan Cha Zhe Wang·2025-07-14 03:09Core Viewpoint - The preliminary investigation results of the recent crash of an Air India Boeing 787 have raised questions about why the fuel switches of the aircraft were turned off, leading to engine failure and the subsequent crash, which resulted in over 270 fatalities [1][3][4]. Group 1: Investigation Findings - The Indian Aircraft Accident Investigation Bureau (AAIB) reported that both engines' fuel switches were turned off almost simultaneously shortly after takeoff, causing fuel supply interruption and engine shutdown [3][4]. - The AAIB's preliminary report did not clarify how the switches were turned off during flight, but cockpit voice recordings indicated a pilot questioned the action, with the other pilot denying involvement [4][5]. - The aircraft's black boxes have been recovered, and an investigation is ongoing with international assistance to determine the cause of the crash [3][4]. Group 2: Regulatory Response - The FAA and Boeing have communicated that the design of the fuel switch lock does not pose a safety issue, and there is no need for airworthiness directives for any Boeing models, including the 787 [1][3]. - Despite a previous FAA recommendation in 2018 to check the fuel cutoff switch locking mechanism, Air India did not conduct the checks as the guidance was non-mandatory [4][5]. Group 3: Expert Opinions - Aviation experts have expressed skepticism about the likelihood of simultaneous accidental activation of both fuel switches, suggesting that pilot error is unlikely based on the available evidence [4][5]. - The investigation is focusing on whether the switches were intentionally turned off and who might have been responsible, as the circumstances surrounding the crash remain unclear [5][6]. Group 4: Public Reaction - Families of the victims have expressed dissatisfaction with the preliminary report, seeking more substantial explanations regarding the crash and its causes [6].
