Probable cause

The Start Operability Bleed Valve (OBV) fuel return adapter-fitting fractured and separated in cyclic fatigue, which allowed fuel to spill onto a hot engine case that ignited the undercowl fire. The OBV fuel adapter-fitting was dropped and the damage reduced its load carrying and fatigue capability, eventually leading to its failure.
