NCA suspends flights over 747 maintenance discrepancy

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.

Protracted checks keep NCA 747 fleet out of action

Japanese freight operator Cargo Airlines" >Nippon Cargo Airlines expects its services to remain suspended for at least another week, to allow more time for maintenance record checks.

NCA had grounded its fleet, comprising 11 Boeing 747-8Fs and -400Fs, as a precaution on 17 June after discovering inconsistencies in records relating to oil supply on one of the -8Fs.

It says it needs to ensure all its maintenance records are accurate and complete.

"At that time, we anticipated that the suspension of the operation would last at least about one week," states the carrier. "However, the verification of the records will take longer than originally expected."

NCA says the first aircraft will not resume services for at least another week, and the rest of the fleet will be re-introduced in sequence as checks are completed.

FAA requires airlines to replace GEnx-2B fuel manifolds

The Federal Aviation Administration is ordering airlines to replace fuel manifolds on some GE Aviation GEnx-2B67 engines, which power Boeing 747-8s, due to the risk of an engine fire.

An airworthiness directive that takes effect on 4 January comes in response to an engine fire caused by "low-cycle fatigue cracking of the fuel manifold".

The order requires airlines to replace the manifolds during the next shop visit.The issue affected 424 GEnx-2B engines worldwide, but GE already issued a service bulletin and only 140 engines still require fixes, the company says.

Those 424 engines compose the bulk of engines on the worldwide in-service fleet of 123 747-8s and 747-8Fs, according to Flight Fleets Analyzer.

US airlines operate only two affected engines, the directive says.

The US aviation regulator has previously issued airworthiness directives addressing problems with fuel manifolds on GEnx-1A engines, which power 787s.

In 2017, the FAA required airlines to replace some GEnx-1A fuel manifolds in response to an in-flight engine shutdown caused by a fuel manifold fracture.
