This amendment adopts a new airworthiness directive (AD) that is applicable to Auxiliary Power International Corporation (APIC) Model APS3200 Auxiliary Power Units (APUs). This action requires replacement of the existing Electronic Control Box (ECB), incorporating its On Board Replaceable Module (OBRM) programmed with originally approved software version 2.0.2 or 3.2 with improved software version 4.1, or replacement of the existing OBRM of the ECB programmed with version 2.0.2 or version 3.2 with a new OBRM programmed with software version 4.1. This amendment is prompted by reports of continued fuel flow to the APU after the APU was commanded to shutdown, resulting in internal APU fires. The actions specified in this AD are intended to prevent internal APU fires due to ECB malfunction, which, if left unnoticed by flight or ground crews, could result in damage to the aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
