Air India allowed to fly Boeing 737 Max

Date: 28 August 2021 Tags: Services

Issue

The commercial operations of Boeing 737 Max were permitted by the DGCA after it was satisfied with the results.

 

Background

The 727 Max model of the commercial aircraft maker was banned from flying in 2019 after incidents of crashes in different parts of the world.

 

Details

  • The 737 Max first came under the radar after an aircraft belonging to Indonesian airline company crashed in the Java Sea shortly after takeoff.

  • Another crash took place near the Ethiopian capital of Addis Ababa in 2019 when the same model crashed after taking off.

  • A consensus was reached to ground operations of these flights until pending of investigation. At that time Indian company SpiceJet was running these aircrafts.

  • China was the first country to ground these planes. After the ban was reversed and India also following the suit, China still has not uplifted the ban.

 

Outcome of investigation

  • The aircraft contains a maneuvering characteristics augmentation system (MCAS) that pushes the nose down to prevent the aircraft from stalling mid-air if angle of attack is high.

  • The faulty system misread the angle of attack and pushed the nose of the aircraft down, causing the aircraft to lose altitude and later crash.

 

Making changes

  • Boeing made some minor technical changes to the system. In addition, pilots were given flight simulation training to understand MCAS.

  • The DGCA said that after the uplifting of ban by other countries, these planes have been flying without any untoward incidents.
