Ahmedabad Air Crash: A Safety Wakeup Call

AHMEDABAD AIR CRASH: A SAFETY WAKEUP CALL

Context:

• The recent crash landing of an Air India Boeing 787 Dreamliner (Flight AI 171) from Ahmedabad to London, shortly after takeoff on June 12, 2025, resulted in significant casualties.
• It has also highlighted critical aviation safety concerns and broader systemic challenges, particularly during high-risk flight phases.
• Incident Overview:
  • Aircraft: Air India Boeing 787 Dreamliner (Flight AI 171).
  • Route: Ahmedabad to London Gatwick.
  • Event: Faced technical issues and crashed shortly after takeoff.
  • Casualties: Almost all 241 passengers and crew killed except 1.
  • Location: Crashed into Meghani Nagar, a densely populated residential and medical college area near Ahmedabad airport, causing ground-level casualties.
• Cause: Not immediately known.
• Immediate Emergency Signalled:
  • The pilot issued a “Mayday” call within seconds of takeoff, indicating a life-threatening emergency.
  • No further communication followed, suggesting instant system failure or structural damage.
• Breakdown in Real-Time Air-Ground Coordination:
  • Despite the Mayday call, Air Traffic Control (ATC) could not establish further contact.
  • Raises concerns over the efficacy of emergency protocols between cockpit and ATC during critical moments.
• Highly Experienced Pilot:
  • The Captain had over 8,200 flying hours, including 1,100 hours on the Boeing 787.
  • This experience profile makes human error less likely, shifting focus towards mechanical failure or technical glitch.
• Crash in Civilian Zone:
  • Impact in a residential and medical college area highlights the urgent need for safe buffer zones around airports in urban areas.

• DGCA and Safety Regulation Challenges:
  • Directorate General of Civil Aviation (DGCA) acknowledged the emergency but could not intervene effectively.
  • Reveals the need for stronger monitoring systems, quicker response infrastructure, and regular audits of high-risk aircraft.

KEY AVIATION TERMINOLOGIES

• Mayday Call:
  • An emergency radio signal used by aircraft and ships to request urgent help.
  • Must be used only for genuine emergencies; false calls carry severe penalties.
• Directorate General of Civil Aviation (DGCA):
  • An attached office of the Ministry of Civil Aviation, Government of India.
  • Functions:
    • Regulatory Body for Aviation Safety: Ensures safety of aircraft, passengers, airline operations in India.
    • Controls Air Transport Services: Regulates flights within India and those to/from the country.
    • Enforces Aviation Laws: Ensures airlines follow air safety rules and maintain aircraft standards.
• Black Box (Flight Recorders):
  • Essential tools for accident investigation.
  • Aircraft must have two types:
    • Cockpit Voice Recorder (CVR): Captures conversations and cockpit sounds.
    • Flight Data Recorder (FDR): Stores over 80 types of flight data (altitude, speed, heading, autopilot status, etc.).
  • Location: Usually at the tail end of the aircraft for maximum protection.
  • Construction: Stored in strong, protected units with insulation to resist fire, water, and impact.

WHY ACCIDENTS GENERALLY OCCUR DURING TAKEOFF OR LANDING?

• Statistical Evidence: Data from IATA (2005–2023) and Boeing (2015–2024) consistently shows most crashes happen during landing (53% IATA) and takeoff/initial climb (8.5% IATA, 20% Boeing fatal accidents).
• Cruise phase has the lowest fatal accident rate despite highest exposure.
• Contributing Factors:
  • Limited Time & Space for Correction:
    • Pilots have minimal time and space to react during these phases.
    • No altitude buffer to correct errors or system failures (unlike cruise altitude where planes can glide).
  • Aircraft Under Maximum Stress:
    • Takeoff: Engines and airframe experience maximum pressure to generate lift.
    • Landing: Aircraft must simultaneously manage speed, alignment, descent, and runway conditions.
  • External Risk Factors:
    • Lower altitudes are more prone to bird strikes, turbulence, wind shear, and poor visibility.
  • Pilot Workload:
    • Landings are particularly demanding, requiring complex, real-time decisions.
  • Stall Risk (Especially during takeoff):
    • Wing Stall: Occurs when an aircraft’s wing suddenly loses lift.
    • This happens when the angle of attack (angle between wing and oncoming air) becomes too steep (typically >15-20 degrees).
    • Leads to turbulent airflow over the wing, detachment, sudden lift drop, and loss of altitude.

BOEING 787 DREAMLINER: FEATURES & SCRUTINY

• Aircraft Type: Next-generation, long-haul jet (introduced 2007).
• Key Features: Carbon fibre composite structure (lighter), 25% more fuel efficient than older models, improved cabin comfort.
• Scrutiny: Crash intensifies scrutiny on Boeing, already under pressure from prior 737 MAX crashes.
• Safety Concerns & Incidents:
  • FAA investigations into production practices.
  • Whistleblower allegations (Sam Salehpour on fuselage fastening, John Barnett on substandard parts).
  • Past incidents: 2013 global grounding due to lithium-ion battery fires, 2024 Latam Airlines 787 plunge (human error).

ECONOMIC IMPACT OF THE CRASH

• Fall in Boeing’s Share Price: Immediate ~8% drop in pre-market trading, reflecting investor fears about safety and future sales.
• Rise in Aviation Insurance Premiums:
  • Seen as a “significant event” by global insurance industry.
  • Likely to lead to higher premiums worldwide, especially for wide-body aircraft like the 787.
  • Stricter policy renewals and terms of coverage.
• Reinsurance Cost Escalation:
  • Insurance for large aircraft is typically shared globally via reinsurance.
  • This crash could increase reinsurance costs, particularly if similar incidents occur.
• Financial Liability for Air India & Tata Group:
  • Potential liability burden exceeding ₹500 crore (compensation, legal costs, aircraft damage).
  • Reputation and financial stress despite swift humanitarian response.
• Impact on Aircraft Manufacturing Sector:
  • May further delay deliveries or affect demand for Boeing’s 787 models.
  • Impacts global aviation production and supply chains.
• Impact on India’s Aviation Sector:
  • Potential downgrade in global rankings.
  • Stricter regulations and increased scrutiny from international aviation bodies.
  • Decline in foreign investments due to safety concerns.

WAY FORWARD

• Proactive Aircraft Health Checks: Implement modern tools for early detection of technical problems before every flight.
• Enhanced Training: Improve pilot and ATC staff training for emergencies, incorporating regular practice and mock drills.
• Airport Buffer Zones: Enforce stricter regulations to avoid construction of homes/schools too close to airports to minimize ground casualties.
• Aircraft Audits: Ensure older aircraft strictly follow safety rules and undergo more frequent inspections.
• Smart Technology Integration: Utilize advanced technology for early warning of engine or system malfunctions.
• Transparent Investigations: Ensure crash investigations are open, prompt, and transparent, using findings to improve safety rules and protocols.
• International Cooperation: Strengthen collaboration with international aviation bodies (ICAO, FAA, NTSB, AAIB) for best practices and incident analysis.
