Nippon Cargo Airlines (NCA) has submitted the preventive measures for the Business Improvement Order to make sure maintenance and airworthiness issues do not happen again.
The Japanese government’s Ministry of Land, Infrastructure, Transportation and Tourism (MLIT) after maintenance issues were discovered along with problems with record keeping.
When NCA received the order, it says internal processes and controlled would be re-evaluated since measures for the written warning from the MLIT on 5 October 2016 did not prevent the same discrepancies.
NCA said it would utilise a third party to assist in evaluating the “root causes of our failure” and examine preventive measures “immediately”.
The airline’s fleet was grounded from 17 June while all maintenance records were verified, with operations restarting on 4 July.
Two aircraft, JA18KZ and JA05KZ are back in operations while the other nine are still grounded for verification of maintenance records and airworthiness certification.
NCA says: “We sincerely apologise for the inconvenience that we caused our customers from the grounding of the aircraft and the suspension of the flights. We also apologise for the loss of trust as a result of the Business Improvement Order.”
