The number of accidents in restricted areas at airports across Japan from April to November this year hit a record high of 38.

The transport ministry says airports are required to report to the ministry accidents in parking aprons and other restricted areas.

Accidents that must be reported include those in which ground workers are injured and unable to work for four or more days, damage is caused to aircraft, or passengers are injured.

NHK learned about the 38 accidents from information disclosed by the ministry and other sources.

The number is the highest for the period since record-keeping began in fiscal 2014.

Of the 38 accidents, 21 involved injuries to ground staff, 10 damage to aircraft and seven injuries to passengers.

Most of the accidents appear to have involved workers who guide airplanes or handle checked baggage.

A transport ministry official says there is confusion at airport restricted areas as workers have not gotten sufficient experience due to plummeting demand for air travel during the coronavirus pandemic.

Another official says most accidents result from human error, and that possible causes of such error must be identified and information shared to prevent more accidents.
