HONG KONG — Ten of 49 TransAsia Airways pilots failed emergency proficiency tests ordered by the Civil Aeronautics Administration of Taiwan after a deadly plane crash in the capital, Taipei, last week, the aviation regulator announced on Wednesday.

The results were another black mark for TransAsia, Taiwan’s third-largest airline, which has had two deadly crashes in less than seven months. The aviation authority said it was planning to increase the testing of pilots and aircraft at the airline in an effort to improve safety.

The pilots of the airline’s ATR turboprops who failed the test will be suspended pending further training in handling emergency situations, the aviation authority said. It said an additional 19 pilots still had not taken the test and could not fly until they had passed.
