日航屢次有飛機修理失誤事件

A few weeks ago the Yomiuri News on-line reported the following:

ＪＡＬ整備ミス１６件…「異例の頻度」と国交省

2014年05月31日 09時16分

　日本航空が昨年１０月から今年５月にかけて、計１６件の整備ミスを起こしていたことが３０日、国土交通省への取材でわかった。

　運航に支障が出たケースはなかったが、国交省は「異例の頻度でミスが起きている」として、日航に原因究明と再発防止を指導した。

　国交省や日航によると、３月にボーイング７７７型機のエンジンを整備した際、着陸時の減速に使う逆噴射装置の部品を取り付け忘れ、約１か月にわたって運航を続けていた。最悪の場合、エンジンの一部が損傷する恐れがあったという。

　また、ボーイング７６７型機の主脚の部品を付け忘れ、制動に影響が出る恐れが出たほか、資格のない整備士が整備作業の最終確認をしていたケースもあった。

    On the 30th (May) by a news coverage on the Ministry of Land, Infrastructure, Transport and Tourism, it turned out that Japan Airlines had made maintenance mistakes in total on 16 occasions from October last year to May this year.

    Although no operational trouble incidents had occurred, as "the frequency of mistakes occurred was exceptional", the Ministry of Land, Infrastructure and Transport instructed Japan Airlines to know the cause and to prevent future recurrence.

    According to Ministry of Land, Infrastructure and Transport and also the Japan Airlines, when the engine of a Boeing 777 was fixed in March, the company forgot to attach back the parts of a retrorocket device which was used for slowing down at the time of landing, and the flying was continued for about one month. It was said that in the worst case scenario, there was a possibility that some parts of the engine might have been damaged.

    Moreover, the company forgot to attach back some parts of the main leg of the Boeing 767, and a possibility was that this might affect the braking. Also there was a case which a final maintenance confirmation was carried out by an unqualified mechanic.

This report could be a PR disaster for JAL.
