The transport ministry on Tuesday conducted an on-site inspection of Japan Airlines Co. after one of its pilots was arrested in Britain for heavy drinking before a flight from London to Tokyo late last month.

Through the inspection at the company's Tokyo headquarters and other offices through Thursday, the ministry is expected to confirm measures JAL outlined in a report submitted earlier to prevent a similar incident, as well as details of the misconduct.

“We will sort out and analyze information to be obtained in the inspection to strictly instruct and supervise the company. Then we will consider necessary steps including administrative punishment,” transport minister Keiichi Ishii said at a news conference.
