Flight IX 611 – What Went Wrong at Trichy?
(0:00-0:30) Introduction & Hook

"Imagine you're on a plane, ready for takeoff, and suddenly, everything goes wrong. That's exactly what happened to Air India Express Flight IX 611 on October 11, 2018. What started as a routine flight from Trichy, India to Dubai turned into a heart-stopping incident that revealed a series of critical failures. Today, we dive deep into the official investigation report to understand how a seemingly minor issue escalated into a near-catastrophe, and what lessons were learned to prevent future accidents."
(0:30-1:30) The Flight and the Unexpected Problem

"Flight IX 611 was a Boeing 737-800, carrying 130 passengers and 6 crew members. The flight was under the command of an experienced Pilot-in-Command, or PIC, and a Co-Pilot. Their previous flight together had been uneventful, and the aircraft was declared serviceable after a routine check and a quick main wheel change."
"As the aircraft began its takeoff roll on Runway 27 at Trichy Airport, everything seemed normal until the aircraft reached a speed of 117 knots. Suddenly, the unthinkable happened: the Pilot-in-Command's seat recliner mechanism failed, causing his seatback to collapse backward! This unexpected jolt caused the PIC to lose his balance and inadvertently move both the throttle levers and the control column back."
(1:30-2:30) Critical Moments & Crew Response
(Visual: Animation showing thrust reduction, then a tail strike. Text overlay: "Thrust reduced from 98% to 77%.")
"In a moment of pure chaos, the PIC, unsettled, quickly handed over controls to the Co-Pilot. It took him about 5 seconds to adjust his seat and regain his position. Here's where it gets critical: neither pilot noticed that the engine thrust had been significantly reduced from 98% to 77% during this scramble."
"With limited runway remaining and the aircraft not yet at its V1 speed of 143 knots, the PIC took back control and initiated rotation. The aircraft's rotation felt slower, and an unusual amount of force was needed on the control column. The result? A tail strike on the soft ground within the Runway End Safety Area."
(2:30-3:30) Impact and Initial Awareness
(Visual: Images of the damaged localizer antenna and boundary wall. Text overlay: "Aircraft hits Localizer Antenna and Boundary Wall.")
"But it didn't stop there. The aircraft continued past the paved surface, hitting five units of the airport's localizer antenna and then the airport boundary wall. Just as the aircraft hit the wall, the thrust levers were finally advanced – a full 25 seconds after the initial reduction."
"Back at Trichy ATC, a red indication flashed on their NAV aids status monitor, signaling an issue with the ILS localizer. Soon after, CISF security reported observing smoke and damage to the ILS Localizer antenna and a section of the perimeter wall, confirming the impact. When ATC informed the crew, their initial response was 'all operations normal.'"
(3:30-4:30) In-Flight Checks & The Diversion
(Visual: Animated map showing the flight path diversion from Dubai to Mumbai. Text overlay: "Destination: Dubai. Diverted to Mumbai.")
"Despite the alarming news from ATC, the crew, after performing confidence checks in the climb phase – checking engine instruments, system indications, and recycling the landing gear – believed everything was satisfactory. They even confirmed normal pressurization and hydraulic system readings at cruise altitude."
"However, the situation on the ground was clear. An Air India Express AME inspecting the accident site confirmed debris belonging to their aircraft and the possibility of severe damage. While the aircraft was over the Arabian Sea, Air India Operations Control Centre, along with Mumbai and Muscat ATC, instructed the crew to divert to Mumbai.
