Two Virgin Australia aircraft have been temporarily pulled from service after the airline became aware their engines were fitted with unauthorised parts.
Virgin confirmed on Monday the affected aircraft were part of its fleet of Boeing 737-800s, which fly most of its domestic services between destinations including Melbourne, Sydney, Brisbane and Perth.
The airline became aware of the issues after being notified of falsified certification documents for aircraft parts which came from UK-based supplier AOG Technics, as first reported by Bloomberg.
AOG supplies engine parts that power many Airbus A320s and Boeing 737s, two of the most common types of commercial aircraft in the world.
A low-pressure turbine blade on VH-VUT, a Boeing 737-800, was replaced last week after the airline was notified of the false documents.
