What began as a routine international flight turned tragic in less than a minute. The preliminary report from the Aircraft Accident Investigation Bureau (AAIB) offers a chilling, minute-by-minute reconstruction of events leading up to the deadly June 12 crash of Air India flight AI-171 in Ahmedabad.

The London-bound Boeing 787-8 Dreamliner plunged to the ground just 32 seconds after takeoff, killing nearly everyone on board and several people on the ground. While the report confirms that fuel supply to both engines was cut off seconds into the flight, investigators continue to piece together the causes behind this catastrophic failure.

Here’s a detailed timeline based on the AAIB’s 15-page preliminary findings:

Minute-by-Minute Timeline of AI-171

11:17 AM – Aircraft VT-ANB lands in Ahmedabad from Delhi and logs a defect report related to the stabilizer position transducer (STAB POS XDCR), a sensor that helps control the horizontal stabilizer.

11:55 AM – Replacement crew arrives at the airport to operate the Gatwick-bound flight.

12:10 PM – Troubleshooting is carried out on the earlier reported fault; the aircraft is cleared for flight.

12:35 PM – Flight crew arrives at the boarding gate.

1:13 PM – Pilots request pushback and engine start; ATC grants approval.

1:18 PM – Aircraft leaves the bay.

1:19 PM – Pilots confirm they require the full length of Runway 23 for takeoff.

1:25 PM – Taxi clearance is granted.

1:32 PM – Aircraft transferred from Ground to Tower Control.

1:33 PM – Instructed to line up on Runway 23.

1:37 PM – Cleared for takeoff; wind reported at 240°/06 knots.

1:38 PM – Aircraft reaches maximum recorded speed of 180 knots during takeoff roll. Seconds later, fuel switches transition from RUN to CUTOFF, one after another. Engines lose thrust.

One pilot is heard asking, “Why did you cut off?”

The other replies, “I didn’t.”

1:39 PM – A MAYDAY distress call is transmitted. ATC asks for the call sign but receives no response. Moments later, controllers witness the aircraft crash beyond the airport boundary. Emergency response is activated.

1:44 PM – Crash fire tenders are dispatched from the airport.

Bengaluru, Nov 21: The Karnataka government is facing pressure to overhaul its employment system after a high-level Cabinet sub-committee recommended the complete phase-out of job outsourcing in government offices, boards, and corporations by March 2028. The move is aimed at tackling a systemic issue that has led to the potential violation of constitutional reservation policies and the exploitation of workers.

The Call for Systemic Change

With over three lakh vacant posts currently being filled through private agencies on an outsource, insource, or daily wage basis, the sub-committee highlighted a significant lapse. "As a result, reservations are not being followed as per the Constitution and state laws. It’s an urgent need to take serious steps to change the system. It has been recommended to completely stop the system of outsourcing by March 2028," the panel stated in a document.

The practice of outsourcing involves private companies hiring workers to perform duties for a government agency. Critics argue this model results in lesser salaries, a lack of social security benefits (otherwise available to permanent government employees), and a failure to adhere to the provisions of Articles 14 and 15 of the Constitution, which guarantee equality before the law and prohibit discrimination.

The 'Bidar Model' as a Stop-Gap Solution

To regulate the current mode of employment and reduce worker exploitation until the 2028 deadline, the government plans to establish workers’ services multi-purpose cooperative societies across all districts, following the successful "Bidar Model."

The Bidar District Services of Labour Multi-purpose Cooperative Society Ltd., which operates under the District Commissioner, is cited as a successful example of providing a measure of social security to outsourced staff. Labour Department officials argue this society ensures workers receive their due wages and statutory facilities like ESI (Employees' State Insurance) and PF (Provident Fund), in exchange for a 1% service fee collected from the employees.

legislative push and Priority Insourcing

The recommendations, led by the sub-committee headed by Law and Parliamentary Affairs Minister H K Patil, are set to be discussed at the next Cabinet meeting. The committee has proposed the introduction of the Karnataka Outsourced Employees (Regulation, Placement and Welfare) Bill 2025.

In a move addressing immediate concerns, Labour Minister Santosh Lad, a member of the sub-committee, has reportedly assured that steps will be taken over the next 2-3 years to insource workers in "life-threatening services" on a priority basis. This includes essential personnel like pourakarmikas (sanitation workers), drivers, electrical staff in the Energy Department, and Health Department staff handling contagious diseases. The transition aims to grant these workers the long-term security and benefits they currently lack under the outsourcing system.

Angry outbursts, long queues, and desperate appeals filled airports across India today as IndiGo grappled with a severe operational breakdown. Hundreds of flights have been cancelled or delayed, leaving thousands of passengers stranded through the night and forcing many to spend long hours at helpdesks.

Social media was flooded with videos of fliers pleading for assistance, accusing the airline of misleading updates, and demanding accommodation after being stuck for 10 to 12 hours at airports such as Hyderabad and Bengaluru.

What Triggered the Meltdown?

IndiGo has attributed the widespread disruption to “a multitude of unforeseen operational challenges.” These include:

•    Minor technology glitches
•    Winter-season schedule adjustments
•    Bad weather
•    Congestion in the aviation network
•    New crew rostering rules (Flight Duty Time Limitations or FDTL)

Among these, the most disruptive has been the implementation of the updated FDTL norms introduced by the Directorate General of Civil Aviation (DGCA) in January 2024.

These rules were designed to reduce pilot fatigue and improve passenger safety. Key changes include:

•    Longer weekly rest periods for flight crew
•    A revised definition of “night,” extending it by an extra hour
•    Tighter caps on flight duty timing and night landings
•    Cutting night shifts for pilots and crew from six per roster cycle to just two

Once these norms became fully enforceable, airlines were required to overhaul rosters well in advance. For IndiGo, this triggered a sudden shortage of crew available for duty, leading to cascading delays and cancellations.

Why IndiGo Was Hit the Hardest

IndiGo is India’s largest airline by a wide margin, operating over 2,200 flights daily. That’s roughly double the number operated by Air India.

When an airline of this size experiences even a 10–20% disruption, it translates to 200–400 flights being delayed or grounded — producing massive spillover effects across the country.

IndiGo also relies heavily on high-frequency overnight operations, a model typical of low-cost carriers that aim to maximise aircraft utilisation and reduce downtime. The stricter FDTL norms clash with these overnight-heavy schedules, forcing the airline to pull back services.

Aviation bodies have also criticised IndiGo’s preparedness. The Airline Pilots' Association of India (ALPA) said airlines were given a two-year window to plan for the new rules but “started preparing rather late.” IndiGo, it said, failed to rebuild crew rosters 15 days in advance as required.

The Federation of Indian Pilots (FIP) went further, calling the crisis the result of IndiGo’s “prolonged and unorthodox lean manpower strategy,” and alleging that the airline adopted a hiring freeze even as it knew the new rules would require more careful staffing.

How Many Flights Are Affected?

In the past 48 hours, over 300 flights have been cancelled. At least 100 more are expected to be cancelled today.

City-wise impact:

•    Hyderabad: 33 expected cancellations; several fliers stranded overnight
•    Bengaluru: over 70 expected cancellations
•    Delhi, Mumbai, Chennai, Kolkata: widespread delays and missed connections

Passengers shared distressing accounts online.

One customer at Hyderabad airport said they waited from 6 PM to 9 AM with “no action taken” regarding their delayed Pune flight. Another said IndiGo repeatedly told them the crew was “arriving soon,” only for the delay to stretch over 12 hours.

IndiGo has apologised for the disruption and promised that operations will stabilise within 48 hours, adding that “calibrated adjustments” are being made to contain the chaos.

What Should Passengers Do Now?

For those flying in the next few days, especially with IndiGo, here are key precautions:

1. Keep Checking Flight Status
Monitor your flight closely before leaving for the airport, as delays may be announced last-minute.

2. Arrive Early
Expect long queues at counters and security due to crowding and rescheduling.

3. Carry Essentials
Pack snacks, water, basic medicines, chargers, and items for children or senior citizens. Extended waiting times should be anticipated.

4. Use Flexible Booking Options
If you booked tickets with a free-date-change or cancellation option, consider using them.
If you haven’t booked yet, prefer refundable or flexible fares, or even consider alternate airlines.

5. Follow IndiGo’s Updates
Keep an eye on IndiGo’s official social media channels and contact customer support for rebooking and refund queries.

What Needs to Change?

Pilot groups have raised concerns not just about staffing but also the planning practices behind it.
The Federation of Indian Pilots accused IndiGo of:

•    Imposing an unexplained hiring freeze despite knowing the FDTL changes were coming
•    Entering non-poaching agreements that limited talent movement
•    Keeping pilot pay frozen
•    Underestimating the need to restructure operations in advance

They have urged DGCA to approve seasonal schedules only after airlines prove they have adequate pilot strength under the new norms.

ALPA also warned that some airlines might be using the delays as an “immature pressure tactic” to push DGCA for relaxations in the new rules — which, if granted, could compromise the very safety standards the norms were meant to protect.

Both pilot bodies stressed that no exemption should dilute safety, and any deviations should be based solely on scientific risk assessment.

Is a Solution in Sight?

While IndiGo says normalcy will return within two days, aviation experts believe that fully stabilising operations could take longer, depending on how quickly the airline can:
•    Re-align rosters
•    Mobilise rested crew
•    Boost staffing
•    Adjust its winter schedule to match regulatory requirements
Passengers are advised to remain prepared for continued delays over the next few days as the airline works through its backlog.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.
