Core Viewpoint - Following the investigation of an Indian aviation accident involving a Boeing aircraft, multiple airlines worldwide have initiated enhanced inspections of the fuel switch locking mechanisms on various Boeing models [1][2]. Group 1: Actions Taken by Airlines - The Indian Directorate General of Civil Aviation (DGCA) has mandated urgent inspections of fuel switches and locking systems on Boeing aircraft operated by domestic airlines, including Air India, IndiGo, and SpiceJet [1]. - Alaska Airlines has not yet received guidance from Boeing and has not taken any action, while Southwest Airlines completed relevant checks in 2018 and will maintain communication with the FAA and Boeing for any necessary additional measures [2]. - Singapore Airlines has completed preventive checks on its Boeing 787 fleet, confirming all equipment is functioning normally [2]. Group 2: International Responses - The South Korean Ministry of Land, Infrastructure and Transport has required local airlines to inspect their aircraft fuel control switches based on the FAA's 2018 recommendations, with Korean Air already initiating checks [3]. - Japanese airlines All Nippon Airways and Japan Airlines are also conducting inspections in accordance with the FAA's 2018 guidance [3]. - Several Middle Eastern airlines have begun inspections of their Boeing fleets, with Oman Air completing checks on approximately 12 Boeing 787 aircraft and currently inspecting its Boeing 737 fleet [3]. Group 3: Findings and Recommendations - The preliminary report from the Indian aviation accident investigation indicated that the fuel switch on the involved aircraft was switched from "on" to "off" before the crash, leading to an interruption in fuel supply to the engines [1]. - The FAA had previously issued a notice in 2018 recommending operators of Boeing 787 and other models to check the fuel switch locking function to prevent accidental displacement [1].
