Japan Airlines has vowed to work on raising safety awareness among its crew and to revise its safety management system following a series of aircraft mishaps in recent months.

“The management (team) will take the lead in rebuilding the safety system as a company and implement measures to prevent a recurrence to regain the trust of society and our customers in the safety of our operations,” Munekazu Tachibana, its senior vice president of corporate safety and security, said at a news conference Tuesday.

Earlier in the day, the airline submitted a report to the transport ministry following a ministry probe.

JAL said in the report that one factor that had played a role in the incidents was the inability of crew members to take a step back to assess the danger level after the mishaps, which resulted in them reoccurring.

Noting that there was a tendency among crew members to get used to their routine work and not think too much about what they were doing, Tachibana emphasized the importance of taking a step back and reevaluating their procedures.

In its report, JAL said multiple incidents had been caused by pilots coming under pressure due to time constraints, which resulted in them misunderstanding instructions from the control tower or misreading aircraft instruments.

Another reason identified by the airline was that, despite the repeated occurrence of certain mishaps, proper risk management was not put in place. In addition, there was also a lack of follow-up to ensure that crew members fully understood why new measures were being introduced.

JAL said it will also conduct intensive training on safety operations across the company to reestablish employee awareness. The company plans to gauge the effectiveness of such training by conducting online tests and group meetings, for example.

The airline will also consider whether to reprimand employees whose oversight results in mishaps in the future.

Between November and May, five major incidents involving JAL aircraft were reported, prompting the transport ministry to issue the airline a stern warning and conduct an on-site inspection at its facilities late last month.

The most recent incident on May 23 involved the wings of two JAL planes colliding when taxiing on Haneda Airport’s parking apron.

Three of the five incidents involved passenger planes crossing stop lines and entering runways without permission from air traffic controllers. These occurred at Fukuoka Airport in May, San Diego International Airport in February and Seattle-Tacoma International Airport last November.

The fifth incident involved a JAL flight from Dallas in April that was canceled due to the pilot drinking too much in his hotel room the night before. Although company regulations require crew members to keep one another from drinking excessively before a flight, none of them did in this case.

In response to this incident, the airline has, for the time being, implemented a new rule banning flight crews from consuming alcohol during both their domestic and international layovers.
