During preventative maintenance (pm), the autopulse platform (b)(6) passed the preliminary functional testing but failed the load cell characterization test.The root cause of the noted issue was the malfunctioning load cell #2, likely attributed to the age of the platform, failed component(s), or mishandling such as a drop.The autopulse platform was manufactured in december 2009 and is over 14 years old, well beyond its expected service life of 5 years.The failed load cell #2 was replaced to remedy the fault.Subsequently, the autopulse platform passed a run-in test using the large resuscitation test fixture (lrtf) for 15 minutes.Visual inspection of the autopulse platform did not show any apparent physical damage.Following service, a brake gap inspection was performed and verified the brake gap was within the specification.Another load cell characterization test was performed and confirmed that both cell modules were functioning within the specification.The autopulse platform was subjected to a final run-in test using the 95% large resuscitation test fixture (lrtf) with known good test batteries until discharged without any fault or error.Historical complaints were reviewed for service information related to the reported complaint, and there were no similar complaints reported for the autopulse platform with serial number (b)(6).
