These inspections cover everything from the aircraft's exterior and engines to its flight controls and cabin systems. Any discrepancies are addressed before the aircraft is cleared for takeoff.
  • Maintenance Programs: Airlines follow strict maintenance programs prescribed by the aircraft manufacturer and regulatory authorities. These programs involve regular inspections, repairs, and replacements of components to ensure that the aircraft remains in optimal condition. Maintenance checks range from routine visual inspections to comprehensive overhauls that occur every few years.
  • Crew Training: Pilots undergo extensive training, including simulator sessions that simulate various emergency scenarios. This training prepares them to handle unexpected events such as engine failures, system malfunctions, and adverse weather conditions. Cabin crew members are also trained in emergency procedures, including evacuation techniques, first aid, and fire fighting.

Regulatory Oversight

  • Certification: Aircraft manufacturers must obtain certification from regulatory authorities such as the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA) in Europe. This certification process involves rigorous testing and evaluation to ensure that the aircraft meets strict safety standards.
  • Continuous Monitoring: Regulatory authorities continuously monitor airlines' safety performance and conduct regular audits to ensure compliance with regulations. They also investigate accidents and incidents to identify potential safety issues and implement corrective actions.

What Happens in the Event of a Crash?

Despite all the precautions, accidents can still occur. When they do, a series of procedures and protocols are activated to investigate the cause, provide assistance to survivors, and prevent similar incidents in the future. Let's explore what happens in the event of an Air India 787 crash.

Immediate Response

  • Emergency Services: The moment an aircraft crash is reported, emergency services, including fire departments, medical teams, and law enforcement agencies, are dispatched to the scene. Their primary focus is on rescuing survivors, providing medical assistance, and securing the area.
