Plain English Summary

3/10 complexity

This AD requires operators of aircraft with GTCP36 APUs fitted with load-compressor impeller P/N 3822270-4 to either install an external load-compressor containment shield or replace the impeller with P/N 3822270-5. APUs already fitted with P/N 3822270-5 must have a containment shield fitted. CASA’s delegate enforces the rule and refers to AlliedSignal service bulletins. Aircraft operators pay for parts, labour and shop time; compliance deadlines are either at next shop visit or within specified months/cycle limits, changing maintenance choices and costs.
