SIA stated that it has not experienced the issues reported in media articles, in response to queries about Qatar Airways' move to ground 13 of its Airbus A350s over concerns about material degradation in the aircraft body.
Singapore's national carrier had 55 A350s in its operating fleet as at the end of the last quarter. They form a core part of SIA's fleet.
Qatar Airways announced last Friday it had been instructed by its regulator to ground 13 A350 planes. It said this was due to a "significant condition" across the fleet in which the fuselage surface below the paint was degrading at an accelerated rate.
Qatar Airways chief executive Akbar Al Baker said in a statement that the airline expects Airbus to identify the root cause and permanently correct the issue before it takes any further delivery of the aircraft.
Reuters news agency reported that Qatar Airways has periodically criticized France's Airbus and its US rival Boeing for delays or quality lapses.
Reuters also reported that Airbus and Boeing executives have accused Qatar Airways of seizing such details in the past to delay taking deliveries or gain leverage in other negotiations, a suggestion that the carrier has denied.
