The cause of the crash of flight 789 two weeks ago is POSSIBLY wear and tear. The aircraft was manufactured in 1988 and has since been operated by several Air France subsidiaries, until it appeared on the wholesale market in the late 1990s and early 2000s. The investigation is ongoing. Official causes will be published later.
