The report of the autopulse platform (sn (b)(4)) displaying user advisory (ua) 16 (timeout moving to take-up position) error message was confirmed during functional testing and archive review.The platform is a reusable device and was manufactured on 20 jun 2007 and has exceeded its expected service life of 5 years.The platform is almost 11 years old and has not seen regular preventive maintenance.The platform was functionally tested and upon pressing the start/continue button, it displayed a ua 16 error message on the user control panel.The root cause of the ua 16 error message is attributed to a seized brake gap.The ua 16 error message was cleared after the brake gap was unseized.The archive data was reviewed and contained ua 16 error on (b)(6) 2017, which was the last power up of the platform and not on the reported event date of (b)(6) 2018, thus confirming the reported event.As part of routine service during testing, the platform was examined and found a damaged top cover and the sticky clutch plate.The observed physical damage is attributed to the normal wear and tear due to the age of the device, it is unrelated to the ua 16 error message.The platform was further tested including the load cell characterization check which identified a defective load cell.Additionally, intermittent reading with the ir reader was observed, this is caused by a defective processor board.These observation are unrelated to the reported event.After replacement of the load cell, processor board, top cover and clutch plate; the platform passed further testing with no faults found.Historical complaints were reviewed for service information related to the reported complaint and (b)(4) was reported on (b)(6) 2014 for the autopulse platform with serial (b)(4) for the same reported issue.The brake gap was un-seized to resolve the issue.
