In a statement, the airline said "71 pilots on its fleet of 10 ATR planes will be required to do a test by the Civil Aeronautics Administration and a professional unit to make sure they are all qualified on their jobs."
The decision comes after a TransAsia ATR 72-600 with 53 passengers and five crew members on board plunged into a river in Taipei, leaving at least 35 people dead and eight others missing.
TransAsia said it had also decided to conduct a year-long review of the company, to be carried out by "an authoritative international team".
