Jiji Press TOKYO (Jiji Press) — Japan Airlines said Wednesday that a male supervisory captain, 59, in December 2017 skipped a preflight alcohol test at Narita International Airport and let a fellow captain, 53, take the breath test on his behalf.
The supervisory captain drank alcohol the day before flight duty. The alcohol level in his breath might have exceeded the limit set by the airline if he had taken the preflight test, but the supervisory captain boarded the flight, according to JAL.
On Dec. 2, 2017, the captain checked his breath using a spare alcohol detector before his work on a passenger flight from the airport in Chiba Prefecture to Chicago later in the day.
The detector showed a reading of 0.09 milligram of alcohol per liter of breath, just below the JAL-set limit of 0.1 milligram.
Worrying about the result, the supervisory captain asked his male colleague, a captain who was scheduled to board the flight with him, to take the actual preflight test for him. The colleague captain first advised the supervisory captain to conduct a recheck, but eventually stood in for him in the preflight test.Speech
