Abstract :
The causes and consequences of the misconnected circuits and hoses found in the fire protection systems of 94 in-service Boeing aircraft are examined. The problems were discovered during the massive worldwide inspections of fire protection systems in Boeing aircraft following the crash in England of a British Midland Airways Boeing 737 en route to Belfast in January 1989. These problems, of which there were a number of reports during 1988, did not cause the crash, which was attributed to human error.<>
