Safety Action


Aircraft manufacturer

On 2 September 2004, the aircraft manufacturer reported that it was reviewing the following:

  • failure conditions that can affect lavatory hand basin water shutoff mechanisms
  • design, panel assembly and installation of 717 aft cabin interphones
  • electrical installations associated with 717 aircraft lavatory modules
  • lavatory faucet reliability data.


On 5 December 2004, the aircraft operator reported that its 717 flight simulator landing gear `down' indication during flight on emergency electrical power was incorrect. As a consequence, the aircraft manufacturer made software changes to 717 flight simulators to correct that anomaly.
