Plain English Summary

2/10 complexity

This Airworthiness Directive requires operators of the Boeing 767 models listed in Boeing Alert Service Bulletin 767-24A0126 to install protective sleeving on the 90‑minute APU standby power feeder cable at body station 1351 (left side), following the service bulletin (Requirement). CASA says the sleeving prevents cable damage from shifting cargo that could cause arcing, penetrate the APU fuel‑line shroud and lead to a main‑deck fire; the work must be done within six months, so operators bear the cost and scheduling burden (Background; Compliance).
