Why in the News?
- An Air India Boeing 787 Dreamliner flying from Ahmedabad to London faced technical issues shortly after takeoff.
- This resulted in a crash landing killing almost all passengers and crew.
- This incident highlighted a broader trend – most aviation accidents occur during takeoff and landing, not mid-flight.
- Data from Boeing’s Statistical Summary of Commercial Jet Airplane Accidents (2015–2024) supports this trend.
Key Dimensions of the Ahmedabad Plane Crash:
- Immediate Emergency Signalled
- The pilot issued a Mayday call within seconds of takeoff, indicating a life-threatening emergency.
- However, no further communication followed, suggesting either instant system failure or structural damage.
- Breakdown in Real-Time Air-Ground Coordination
- Despite the emergency call, the Air Traffic Control (ATC) could not establish further contact.
- This raises concerns over efficacy of emergency protocols between cockpit and ATC during critical moments.
- Pilot Was Highly Experienced
- The Captain had over 8,200 flying hours, including 1,100 hours on the Boeing 787 aircraft.
- This makes human error less likely, focusing attention on mechanical failure or technical glitch.
- Crash Within 40 Seconds of Takeoff in Civilian Zone
- The aircraft crashed into a residential and medical college area, causing ground-level casualties.
- Highlights the urgent need for safe buffer zones around airports in urban areas.
- DGCA and Safety Regulation Challenges
- DGCA acknowledged the emergency but couldn’t intervene effectively.
- It reveals the need for stronger monitoring systems, quicker response infrastructure, and regular audits of high-risk aircraft.

Why do accidents happen mostly during take-off or landing?
- Limited Time & Space for Correction:
- During takeoff/landing, pilots have minimal time and space to react if something goes wrong.
- Unlike cruise, there is no altitude buffer to correct errors or system failures.
- Aircraft under Maximum Stress:
- During takeoff, a plane’s engines and body experience the most pressure as they work hard to lift off the ground.
- During landing, aircraft must handle speed, alignment, descent, and possible runway factors all at once.
- External Risk Factors:
- Lower altitudes are more prone to bird strikes, turbulence, wind shear, and poor visibility.
- Landings are further complicated by human error and technical challenges.
What is a Black Box?
- Black boxes are flight recorders that help investigators understand what caused a plane crash.
- Aircraft must have two types of recorders:
- Cockpit Voice Recorder (CVR): captures conversations and cockpit sounds.
- Flight Data Recorder (FDR): stores over 80 types of flight data like altitude, speed, heading, and autopilot status.
- These are usually located at the tail end of the aircraft, where damage is less likely during a crash.
- The black box is stored in a strong, protected unit with insulation to resist fire, water, and impact.
Impact of this on Economy:
- Fall in Boeing’s Share Price:
- Boeing’s share prices went down by nearly 8% in pre market after this incident
- This reflects investor fear about Boeing’s aircraft safety and future sales.
- Aviation Insurance Premiums May Rise
- This crash is seen as a “significant event” by the global insurance industry.
- Experts say it could lead to higher aviation insurance premiums worldwide, especially for wide-body aircraft like the Boeing 787.
- Insurance firms may also become stricter in policy renewals and terms of coverage.
- Reinsurance Cost Escalation
- Insurance for large aircraft is typically shared among multiple global firms via reinsurance.
- This crash could increase reinsurance costs, especially if multiple such incidents happen in a short time.
- Financial Liability for Air India and Tata Group
- Air India may face a liability burden of over ₹500 crore, including compensation, legal costs, and aircraft damage.
- They could also face reputation and financial stress despite its swift humanitarian response.
- Effect on Aircraft Manufacturing Sector
- The incident may further delay deliveries or affect demand for Boeing’s 787 models
- This impacts global aviation production and supply chains.
- Impact on India’s aviation Sector:
- It may face a downgrade in global rankings, leading to stricter regulations and increased scrutiny from international aviation bodies.
- Foreign investments in Indian airlines could decline, as concerns over safety standards may make investors hesitant to fund aviation–related projects.
Way Forward:
- Check aircraft health before every flight using modern tools that can detect any technical problem early.
- Train pilots and air Traffic Control (ATC) staff better for emergencies with regular practice and mock drills.
- Avoid building homes or schools too close to airports to reduce damage if accidents happen.
- Make sure old aircraft follow all safety rules strictly and are inspected more often.
- Use smart technology that can warn the pilot early if something is going wrong in the engine or system.
- Ensure crash investigations are open and quick, and use the findings to improve safety rules.
