## Probable cause

An in-flight fuel fire in the left forward doorpost due to an electrical arc from an adjacent map light switch puncturing a main fuel feed line.  The manufacturer's inadequate design in routing the fuel line in close proximity to electrical arc sources in the doorpost is causal.  A factor in the accident is the probable failure of the doorpost internal component configuration to conform to original design specifications due to aircraft aging issues.
