“The source of the issue has been identified, contained and all newly produced panels conform to all requirements,” Airbus’s spokesperson told the BBC.
A statement continued: “Only inspections will determine where an aircraft may have panels with quality issues and the appropriate action to be taken.”
AFP reported Airbus as saying the number of planes that needed to be checked was “reducing day by day as inspections progress to identify those needing a specific action to be taken”.
The BBC has contacted major airlines that use the A320, including British Airways, American Airlines, Korean Air, Lufthansa Airlines and Delta for comment.
Earlier this week, thousands of Airbus planes were grounded for a software update after it was discovered that intense solar radiation could interfere with onboard flight control computers.
That issue was discovered after a plane travelling between the US and Mexico suddenly lost altitude as a result of the vulnerability, injuring 15.
More than 6,000 Airbus aircraft needed emergency computer updates in one of the largest ever aviation industry recalls.
It resulted in global disruption and flight cancellations over the final weekend of November, a busy time of the year for travel – particularly in the US, where it coincided with Thanksgiving.
Airbus shares have fallen by more than 6.5% in the past five days.
