An Independent Technical Deep Dive into System Behavior, Crew Response & Probable Electrical Vulnerabilities
(A comprehensive systems-based interpretation | Independent dossier – based on publicly available data and the AAIB Preliminary Report)
About the Author:
I’m an air cargo professional with over 20 years of experience across international and domestic air cargo operations and IT enabled Services . I’m also an independent aviation researcher and consultant , IATA-certified DG professional, and hold additional qualifications in ITIL and Cisco systems.
This independent analysis reflects my deep curiosity , knowledge and experience in aviation and commitment to safety.
This is a hypothesis-led, non-official technical reconstruction and deep-dive analysis, based on the AAIB preliminary report and publicly available data. It reflects an in-depth systems-based exploration of the AI171 events.
Key Focus Areas :
• Granular sequencing of system and crew events post-liftoff
• FIFO/LIFO logic to decode functional breakdown progression
• Comparative mapping of abnormal vs expected system behaviors
• Cabin anomalies (ICE, comms, lights) as early stress indicators
• Real-world vs AI171 climb path and thrust output
• Crew alert workload, timing gaps, and cockpit response under pressure
• Plausible overlapping of power pathways between critical/non-critical loads
• Relay/BTU behavior under stress — logic failure, delayed isolation
• Shared upstream BTU/RPDU vulnerabilities across avionics and cabin
• Downstream impact on solenoids, FADECs, actuators, and displays
• Evidence-based rebuttal of pilot error theory (13 observations)
• Probable scenario: Electrical instability triggering fuel cutoff and dual engine failure
Why? Because this incident deserves a clear, structured exploration — one that examines how systems behaved, how power was presumably lost, and how events likely cascaded into a dual engine flameout. Understanding this chain of events can help prevent its repetition.
