A320 Extinguisher Squib light inop Maintenance procedure
One of the squib lights failed to illuminate during the engine fire test during the cockpit preparation. Light illuminated correctly with the Annunciator switch at "Test". Maintenance tried to release the aircraft by MEL stating it was an inop squib light only. End result was a change of aircraft.
My question is this : The MEL referred to a Maintenance Procedure to check the fuctioning of the system. What does this procedure involve? (I asked and he said that he would only check no DISCH light illuminated! Didn't think this sounded adequate!)
Thanks!
