U.K. AAIB issues safety recommendations on EMB-190 interphone system use
20 February 2009

The U.K. Air Accidents Investigation Branch (AAIB) published recommendations following an incident involving an Embraer 190 on January 15, 2008.

During flight, “smoke” was seen to emanate from a galley sink and the flight deck and cabin crews took appropriate emergency action. In the course of the ‘Electrical System Fire or Smoke’ procedure the flight crew established the aircraft on emergency power, after which communications between the flight deck and cabin became difficult. The aircraft landed safely. Deficiencies in the interphone system were identified, and four safety recommendations are made.

Safety Recommendation 2009-017:
It is recommended that Embraer immediately notify all operators, of the Embraer 190 family of aircraft, to inform flight crew of the importance of advising cabin crew when an aircraft is on emergency electrical power.
Safety Recommendation 2009-018:
It is recommended that Embraer immediately notify all operators, of the Embraer 190 family of aircraft, to inform their flight and cabin crew of the functioning of the interphone system when the aircraft is supplied only with emergency electrical power.
Safety Recommendation 2009-019:
It is recommended that Embraer modify the functioning of the interphone systems of Embraer 190 family aircraft to provide crew with the facility to make both normal and emergency calls when the aircraft is supplied only with emergency electrical power.
Safety Recommendation 2009-020:
It is recommended that Embraer immediately notify all operators, of the Embraer 190 family of aircraft, to inform flight and cabin crew of the functioning of the flight deck access system when the aircraft is supplied only with emergency electrical power. (AAIB)
