The total number of potentially affected aircraft, both in production and in service, is decreasing daily as inspections progress, allowing for the identification of those requiring specific action, stated a company spokesperson in a message to AFP following information released by Bloomberg and Les Echos.

The figure of 628 mentioned by the media is “an estimate of the maximum number” of planes likely to be inspected, “which does not mean that all are necessarily affected” by the issues, the company declared.

Airbus “is in the process of inspecting all potentially affected aircraft, knowing that only a portion of them will need intervention,” it added.

The aerospace manufacturer announced on Monday that it had found “quality issues” with the metallic panels intended for its single-aisle aircraft, stating that they had “been identified and contained.”

The revelation of the problem came days after an alert was also issued about the A320s, calling for the urgent replacement of a flight control software program vulnerable to solar radiation.

This measure was taken following an incident at the end of October in the U.S. when a JetBlue plane, flying from Cancun, Mexico, to Newark, near New York, had to make an emergency landing in Tampa, Florida, after suddenly descending.

Airbus, which advised its customers to “immediately stop flights” of about six thousand aircraft, quickly acted on thousands of planes on Friday and Saturday, alleviating fears of significant disruptions to global air traffic.

The A320, with its numerous variants, is the world’s best-selling commercial civil aircraft. Having entered the market in 1988, it had sold 12,257 units by the end of September.
