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.
- Limited Time & Space for Correction:
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.
