Japanese freight operator Nippon Cargo Airlines is suspending services for several days after discovering a maintenance record discrepancy with its fleet.
The carrier says it will halt departures from Tokyo Narita from 16 June and all flight operations from 17 June.
NCA states that it has found an inconsistency regarding the supply of lubricating oil to one of its Boeing 747-8Fs at Narita in early April.
The airline says it cannot rule out the possibility of similar error in the maintenance records of other aircraft.
"We will temporarily suspend all flights operated by the company until aircraft integrity can be confirmed," it adds. NCA expects it will need at least a week to check that its fleet is sound.
The carrier identifies the airframe at the centre of the decision as JA14KZ, a five-year old airframe operated by the airline since new, according to Flight Fleets Analyzer.
NCA had been a launch customer for the 747-8 in late 2005, agreeing to take the freighter version. It received its first 747-8F in mid-2012. All 747-8Fs are powered by General Electric GEnx-2B engines.
