The Civil Aviation Authority of Bangladesh (CAAB) has sent a letter to all of the country's airlines, helicopter operators and flying academies to verify academic certificates of all pilots.
The captain of a Biman flight was napping in the crew rest area, leaving the cockpit of a Boeing 777-300ER technically unmanned, when a passenger had a heart attack.
In February last year, Biman recruited a batch of contractual pilots to fly its Boeing 777-300ER aircraft, claiming that it needed pilots immediately due to a shortage.
