NEW SEVENTH PLAUSIBLE HYPOTHESIS THAT DESERVES LINE OF ENQUIRY — Cockpit Fuel Control Switches Logic Ambiguity During Electrical Transience.
✈️AI171 : Keeping the Memory Alive, Honouring the Lives Lost ✈️ Dear Aviation Professionals, Aero Engineers, Technicians and Enthusiasts. Greetings. As you may be already aware , there are total six plausible pathways/hypothesis that has been researched and identified after an in-depth deep-dive analysis and a granular event timelines including FIFO/LIFO technical evaluations. While engaging in some recent technical exchanges among the community peers, especially with profess

STAB POS XDCR Error - Could that be indicating anything deeper brewing
Further to my last post, I have something important that I present here this time for your kind read and perusal. The efforts as always are solely to keep the AI171 memory still active and try finding plausible hypotheses / likely pathways. This is an independent, personal, unofficial analysis. I bring in here an important point on the stabilizer fault reported and logged in the previous leg of the same Aircraft. The AAIB preliminary report does note that VT-ANB had a stabil

WHAT IF FUEL SWITCHES WERE NEVER TOUCHED BY THE PILOTS - COULD IT EVER BE POSSIBLE ??
Further to previous post, I have something important that I present here for your kind read and perusal. The efforts are solely to keep the AI171 memory still active and not fade away in oblivion with passage of time. Few contentions are seen across the globe strongly believing the theory that pilots may have physically moved the Fuel switches. Well, this movement is theoretically possible in response to a dual engine failure. as part of a relight protocol or to avoid any fu

Likely Sequence of Events - AI171.
Further to my earlier posts , here is a continuation of my independent, unofficial deep-dive analysis. This presentation below that follows in next comment involves an even more granular FIFO/LIFO–based review of data and event sequences, considering multiple pathways, architectural fail-safes & redundancies as well as cross-checks, synergised seamlessly with the AAIB preliminary report, UTC timestamps, and the data available across the public domain — thus likely reaching a

Four credible 787-specific scenarios that could have caused what we saw on AI171:
Recently I came across numerous videos and clips on social media (for ex: YouTube) with 3D simulations regarding the reconstruction of the entire flight path of the ill-fated AI171 crash. First, let me appreciate all the efforts and the hard work behind putting together such a detailed simulations. It’s very clear that a lot of time is dedicated to the analysis. That said, there is one critical aspect in many videos which is technically off the mark, and I’d like to clarify i

Released Version 1.01 of independent technical dossier on AI171.
This updated edition (50 pages, up from previous 46) is a unofficial deep-dive analysis that brings in additional insights — including possible root-cause scenarios around RPDUs, TRUs, FSOVs, FADECs, VFSGs, and AC/DC bus interactions — compiled with the singular intent of learning from this unfortunate tragedy and strengthening future air safety. The link will be shared in the next comment. Disclaimer: This is a purely personal, independent, and unofficial technical dossier p

Suggested Design & Operational Enhancements -Based on the AI171 System Behavior Timeline
As an extraction from my independent unofficial technical analysis “Seconds That Vanished,” I wish to bring to the kind attention of all aviation system engineers, designers, and safety professionals the following 10 system-level suggestions — each based on plausible patterns inferred fr the power/fuel/control logic timeline during AI171’s final climb at AMD, INDIA. — For review and likely consideration of Manufacturers / Airlines / Operators, as feasible: I.

Independent technical dossier of the AI171 incident.
This is a hypothesis-led, non-official technical reconstruction and deep-dive analysis based on the AAIB preliminary report and publicly available data. A few key focus areas include: • Granular sequencing of crew and system events post-liftoff, aligned with timeline markers • Contrasting AI171’s system behavior with the 'heartbeat' of a healthy 787 aircraft — highlighting early divergence indicators • Plausible electrical instability pathways potentially triggering fuel cu
