Safety Recommendation
The Australian Transport Safety Bureau recommends that the
Federal Aviation Administration of the USA:
a) Review location of fire bottles on aircraft to reduce the
possibility of a premature discharge of fire retardant where the
temperature in the area that contains the fire bottle rises above
the setting of the fusible valve.
b) Review the adequacy of the current requirements for
fire-extinguishing systems to include a requirement that the pilot
be provided with an in flight indication of an uncommanded
discharge of fire retardant.
