Summary:

After a normal engine start the Auxiliary Power Unit (APU) was switched off, however the ‘APU STARTER’ light illuminated. The aircraft systems were shut down and a re-start attempted using a ground power unit. During this time smoke was seen emanating from the rear of the aircraft so the crew initiated a rapid passenger disembarkation. Examination of the aircraft found that the APU starter/generator had overheated probably as a result of an APU contactor failure.
