PARIS – Air France's chief executive says he is "not convinced" that faulty speed monitors caused the crash of Flight 447.
Pierre-Henri Gourgeon told journalists on Thursday that replacement external speed monitors - or Pitot tubes - for jet models of the same type as the crashed plane arrived three days before the fatal accident.
Airbus ordered the replacements on April 27 after pilots noted a loss of airspeed data in flight on Airbus A330 and A340 models.
Gourgeon described the incidents as "not catastrophic" and said he did not issue a press release immediately after the accident "because I am not convinced that the sensors are the cause of the accident."
Flight 447 went down in the Atlantic on May 31 with 228 people aboard.
