飛行中の機長と副操縦士、同時に睡眠　インドネシア

【ジャカルタＡＦＰ＝時事】インドネシアの国家運輸安全委員会（ＫＮＫＴ）は、民間航空機の機長と副操縦士が飛行中に同時に寝ていたことが調査で明らかになったのを受け、問題の航空会社に対して、操縦士の疲労管理を行う制度の改善を求めた。２月下旬にＫＮＫＴのウェブサイトに投稿された報告書をＡＦＰが８日、確認した。（写真は資料写真）
　ＫＮＫＴの報告書によると、１月２５日に東南スラウェシ州から首都ジャカルタに向かうインドネシアの航空会社バティック・エアのエアバス「Ａ３２０」機で、機長と副操縦士が飛行中、同時に約２８分間眠っていた。同機には、乗客１５３人と客室乗務員４人が搭乗していた。
　離陸から約３０分後、機長は仮眠を取りたいと副操縦士に伝え、許可を得た。その後、副操縦士が操縦を引き継いだものの、うっかり居眠りしてしまったという。
　ジャカルタの管制センターは、副操縦士との最後のやりとりが記録された数分後に交信を試みたが、応答はなかった。
　最後の通信記録から２８分後に目を覚ました機長が、副操縦士が居眠りをして、同機が航路を外れていることに気付いた。そこですぐに副操縦士を起こして管制センターからの連絡に応答し、航路を修正したという。
　その後、同機は２時間３５分のフライトを終え、目的地に無事に着陸した。
　当局は操縦士の身元を明らかにしていないが、いずれもインドネシア人で３２歳と２８歳。報告書によれば、「副操縦士には生後１か月の双子の子どもがおり、妻の育児を手伝っていた」という。
　ＫＮＫＴはバティック・エアに対し、操縦室内で適切なチェックを定期的に行い、操縦士および客室乗務員に対してフライト前に十分な休息を確保する詳細な手順を作成するよう要請した。
　ＡＦＰは同社に取材を試みたが、コメントは得られなかった。【翻訳編集ＡＦＰＢＢＮｅｗｓ】

The Indonesian air safety agency has called for better pilot fatigue monitoring mechanisms, after an investigation revealed that both pilots of a commercial aircraft had recently fallen asleep in-flight.
A pilot and co-pilot were simultaneously asleep for approximately 28 minutes during a Batik Air flight from South East Sulawesi to the capital Jakarta on January 25, a preliminary report by the National Transportation Safety Committee (KNKT) said.
The report, seen by AFP on Friday, was uploaded to the agency's website in late February.
Indonesia is a vast archipelago with a poor air safety record, despite relying heavily on air transport to connect its thousands of islands.
One of the pilots had not rested adequately on the night before the flight, the report said.
The incident resulted in a series of navigation errors, but the Airbus A320's 153 passengers and four flight attendants were unharmed during the two-hour-and-35-minute flight.
About half an hour after the plane took off, the captain asked permission from his second-in-command to rest for a while, with the request being granted.
The co-pilot then took over command of the aircraft, but also inadvertently fell asleep, the report said.
The second-in-command had one-month twin babies. His wife took care of the babies and he assisted while at home, the report said.
A few minutes after the last recorded transmission by the co-pilot, the area control centre in Jakarta tried to contact the aircraft. It received no answer.
Twenty-eight minutes after the last recorded transmission, the pilot woke up and realised his co-pilot was asleep and that the aircraft was not on the correct flight path.
He immediately woke his colleague up, responded to the calls from Jakarta and corrected the flight path, the report said.
The plane landed safely after the incident.
Investigators did not identify the pilots, but said they were both Indonesians and were aged 32 and 28.
KNKT urged Batik Air to create detailed procedures to conduct proper and regular cockpit checks and to ensure that pilots and cabin crew were well-rested before their flights.
Batik Air did not immediately respond to questions when contacted by AFP.
