Pilots Body Claims System Glitch Caused Air India AI171 Crash, Challenging Official Investigation

The Quick Take

• India's Federation of Indian Pilots alleged a system glitch tripped both engines in the Air India AI171 crash
• The pilots' body claims a simulator test showed manual fuel cutoff takes 18 seconds to drop turbine RPM, challenging alternate theories
• FIP also alleged that government investigators intentionally sidelined India's most experienced captain in the investigation process

The Federation of Indian Pilots alleged that the Air India AI171 crash was caused by a system glitch that simultaneously tripped both engines, directly challenging the official investigation's preliminary findings. The FIP cited a simulator test that reportedly demonstrated manual fuel cutoff takes 18 seconds to cause turbine RPM to drop to the level observed at the time of the accident — a timeline the pilots' body argues is inconsistent with non-systemic causes. This technical challenge to the investigation narrative introduces a contested liability framework that has significant financial implications for Air India, its insurers, and Boeing.

The aviation insurance and legal dimensions of a contested crash investigation are substantial. Until the official cause is definitively established, Air India's liability exposure for the AI171 event remains uncertain — a system glitch finding would direct liability toward Boeing or component manufacturers, while alternative causes could shift liability toward airline operations. This uncertainty directly affects the quantum of insurance claims, the speed of settlement, and the reinsurance cost implications for Air India's hull and liability programme going forward. The FIP's additional allegation that India's top accident investigator was intentionally sidelined introduces a governance concern that could attract international aviation safety body scrutiny.

Watch the official government investigation final report for the cause determination that will set the liability framework and regulatory response. FIP's legal actions and DGCA's public response to the sidelining allegation will indicate whether the investigation maintains international credibility — ICAO and the US NTSB routinely monitor high-profile crash investigations in member nations. The macro variable governing the financial implications of this crash is the final liability determination: if the finding shifts blame toward a systemic aircraft defect, Boeing and its insurers face an internationally significant liability event; if the finding supports an operator-side cause, Air India's IPO risk profile is more materially affected.
