Recommendations and advisories from the Transportation
Dec. 22, 1998 - Board issues safety advisory for
close inspection of MD-11 wiring.
March 9, 1999 - Recommends changes to flight data
and voice recorders after investigators determine six minutes
of data are missing from the Flight 111 recorders: that
recorders operate on independent power supplies and have
battery backup, and that voice recorders have longer recording
Aug. 11, 1999 - Recommends against using insulation
blankets similar to those used aboard Flight 111, and strongly
recommends tougher flammability tests for insulation material.
March 3, 2000 - Advisory for checks of cockpit
maplights after heat damage to insulation blankets is detected
in other MD-11 aircraft.
Dec. 4, 2000 - Recommends crews land planes
immediately if a suspicious odour or smoke is detected.
Aug. 28, 2001 - Board calls for tough new standards
for testing wires, improved flammability testing for all
material used in aircraft construction and a fail-safe
philosophy for the manufacture of aircraft components. Some
components, such as air conditioning systems, may actually
aggravate a fire because their design may spread smoke rather
than contain it, and allow air to feed the fire.
