AUCKLAND, NEW ZEALANDAir New Zealand says it has encountered some issues with paint peeling on the wings of its Boeing 787-9 Dreamliners.

The airline also said that it had been working with the American planemaker to solve the issue. The paint issues are not considered as a safety concern, nor did they affect the structure or integrity of the aircraft.

Air New Zealand did not reveal how the airline’s 14 B787-9s were impacted or how long it would take to resolve the problem.

It’s not the first time Air New Zealand’s Dreamliners have been impacted by an issue. Between 2017 and 2020 Air New Zealand Dreamliners had to ground its Dreamliners due to problems with Rolls-Royce Trent 1000 engines fitted to the aircraft.

Airlines that grounded aircraft because of the Covid-19 pandemic were bringing their 787s back into service first because they are the most effective aircraft for medium and long haul flights.

They are relatively small and fuel-efficient, and also have lower carbon emissions.

Last month, Boeing said some titanium 787 parts were improperly manufactured over the past three years, the latest in a series of problems to plague the wide-body aircraft.

Boeing suspended the delivery of the aircraft and conducted comprehensive inspections across 787 production and within the supply chain, while holding detailed, transparent discussions with the FAA, suppliers, and its customers.

In a similar case, Qatar Airways has grounded 21 of its 53 Airbus A350s over painting quality issues and has entered into a legal dispute with the European manufacturer in the High Court in London.
