Nippon Cargo Airlines (NCA) will resume limited operations on 5 July, after suspending all services since 17 June to make proactive safety checks across its fleet.
The company says investigations for the first aircraft, registered JA18KZ, are likely to be concluded on 4 July, and on 5 July that same aircraft will resume operations on the Tokyo Narita-Shanghai Pudong route.
Flight Fleets Analyzer identifies JA18KZ as a four-year old Boeing 747-8 freighter operated by the airline since new.
It adds the remaining aircraft operations "will resume in sequence as soon as the aircraft safety is confirmed".
NCA grounded its entire fleet of 11 Boeing 747-400Fs and -8Fs on 17 June after discovering inconsistencies in records relating to oil supply on one of its -8Fs, which the airline identified as bearing the registration JA14KZ.
While it had expected to resume operations after a week, a subsequent statement on 22 June stated "verification of the records will take longer than originally expected."
