The report presents the Board's investigation of an accident, involving a bus which caught on fire in the upper right area of the engine compartment. The driver tried to extinguish the fire through the hood access door, but it did not provide adequate access to extinguish the fire. The fire spread to the passenger compartment and destroyed the entire bus. The National Transportation Safety Board determines that the probable cause of the fire was the ignition of oil which leaked from the accessory drive manifold when it came in contact with a hot engine exhaust system component. The fire spread because of (1) the failure of the hood-opening mechanism to operate and permit fire extinguisher access, and (2) the presence of fire-consumable materials in the fire wall of the bus.
