On June 12, 2025, Air India Flight AI-171, a Boeing 787 Dreamliner, crashed just moments after departing Ahmedabad, India, bound for London Gatwick. This catastrophic event resulted in the loss of over 240 lives and sent shockwaves across India and the global aviation community. Though investigations are still underway, several predominant theories have emerged to explain the tragedy. These range from mechanical failures and pilot error to external environmental factors. Examining these theories reveals not only potential causes but also the multifaceted challenges of aviation safety in our modern era.
A primary investigative focus centers on mechanical failures, especially engine malfunction or critical system faults. The pilot’s distress call reporting “no thrust” and “lack of power” signals a likely engine shutdown shortly after takeoff — a rare but deadly complication during one of aviation’s most vulnerable phases. One telling piece of evidence is the deployment of the ram air turbine (RAT), a small emergency power source designed to supply hydraulic and electrical power when engines fail completely. This measure, visible in crash footage and corroborated by wreckage analysis, indicates the crew battled to keep control despite catastrophic engine failures.
Additional mechanical concerns involve systems vital to flight stability and lift, like wing flaps and landing gear. After takeoff, these components must be correctly positioned to optimize aerodynamic performance. Some investigators speculate the landing gear might not have been fully retracted, or a flap malfunction could have hindered the plane’s ability to climb effectively. Such mechanical irregularities, if combined with engine failure, might cause loss of lift or stall conditions that a pilot cannot easily recover from, especially at low altitude and speed. Exploring maintenance logs, previous repair records, and cockpit voice recorder data remains the cornerstone of verifying these mechanical hypotheses.
Alongside mechanical issues, human factors are scrutinized as possible contributors to the crash. The flight crew, with nearly 10,000 cumulative flying hours, was experienced, challenging initial assumptions about pilot incompetence. Nonetheless, aviation disasters often emerge from a complex interplay between human error and technical failures. The cockpit voice recorder and black box analysis aim to shed light on how the crew responded to sudden and severe malfunctions. Some experts suggest that miscommunication, delayed decisions, or improper instrument handling under extreme stress may have compounded the technical problems. For example, mishandling engine thrust settings or failing to retract the landing gear and flaps promptly could exacerbate an already dire situation. Understanding cockpit dynamics during emergencies remains crucial for preventing future tragedies.
External factors, long recognized hazards in aviation safety, continue to be explored as well. Bird strikes, particularly during the critical takeoff phase when engines and vital systems are most exposed, rank high among these concerns. Eyewitness accounts and former pilot testimony suggest a possible bird strike event that might have damaged the engines or flight controls mere seconds after liftoff. This theory aligns with the rapid timeline from takeoff to crash — around 30 seconds — affording the crew almost no time to recover or diagnose issues. Coupled with this are extreme environmental conditions, notably the 40°C temperatures recorded at Ahmedabad on that day. High heat reduces air density, which directly affects lift and engine performance, making aircraft harder to climb and increasingly sensitive to mechanical or operational shortcomings. These environmental stressors might have tipped an already tenuous balance.
In response to the tragedy, Indian aviation authorities launched urgent inspections of all Boeing 787s operating domestically, searching for systemic defects or maintenance oversights. The investigation is notably international, with experts from the U.S. National Transportation Safety Board (NTSB) contributing their expertise to ensure transparency and thoroughness. Multilayered analysis includes correlating black box flight data, cockpit communications, CCTV footage from the airport, and airline maintenance procedures. The fallout from this first fatal 787 accident hits both Air India and Boeing hard, emphasizing the high stakes in aviation safety and corporate reputation.
Despite ongoing inquiry, six interrelated theories currently dominate efforts to understand Flight AI-171’s crash: total engine failure or mechanical malfunction; flap or landing gear issues impeding lift; pilot or co-pilot error in emergency management; damage from bird strikes; environmental and temperature-related performance factors; and potential lapses in airline maintenance or standard operating procedures. Together, they illustrate how no single factor likely caused the disaster but rather a convergence of failures in machinery, human action, and environment.
The tragedy offers a sobering reminder that even with modern technology and stringent regulations, aviation remains vulnerable to unforeseen catastrophes. It simultaneously serves as a catalyst for advancing safety protocols, refining pilot training for emergency scenarios, and revisiting aircraft design elements. As investigators piece together events and decisions leading to this fatal failure, their findings hold the promise of clearer insight and heightened safeguards. Ultimately, progress born from this painful lesson aims to protect the skies, giving future travelers safer journeys and restoring confidence in an industry built on precision, vigilance, and resilience.
