 1. APU Fault Symptom Peculiarities
_______________________________ (Ref. Fig. 301) Whenever the operation of the APU may result in damage to the aircraft, the APU or the Electronic Control Box (ECB) of the APU, the ECB shuts down the APU automatically. The cause of the Shutdown and associated LRUs are stored in the ECB memory. This information is available on the APU system related CFDS menu page APU SHUTDOWNS.
 i.e.  NO FLAME (shutdown cause)
 IGNITION EXCITER P12 (faulty LRU) In parallel the ECB generates a maintenance message with associated ATA Chapter and related Fault Class of the faulty LRU. This maintenance message is available on the Post Flight Report (PFR), which is, in the AIRBUS TSM philosophy, the entry point to the TSM.
 i.e.  ATA 494138 CLASS: 1 IGNITION EXCITER P12
 During several operator conferences concerning the APU TSM it has been shown that likely most operators prefer into TSM with the information of the APU SHUTDOWNS menu, which shows the same faulty LRU as the PFR but additionally the shutdown reason.
 It has been decided to follow the operators preferences to combine the PFR maintenance message with the Shutdown cause in one Fault Symptom in TSM 49:
 i.e.  Source Message ATA Class ECB NO FLAME ASD *
 associated with ECB IGNITION EXCITER P12 494138 1
