Boeing 747-436, G-BNLV
Shortly after the APU was started on the ground, the APU starter motor suffered a catastrophic failure causing it to shear from its gearbox mounting flange. The failure allowed hot oil to be released; the oil ignited and caused a fire in the APU bay. The flight crew shut down the APU, discharged the fire extinguisher bottle and ordered a precautionary passenger disembarkation.
