The QRH of an engine failure might refer to “Engine Fire or Severe Damage or Separation” or “Engine Limit or Surge or Stall” which required memory items, which should be performed by memory. The memory items included requirement to retard the throttle lever of the effected engine until the engine parameters within limit or to idle. Both aforesaid procedures also required to switched off the PACK switch of the affected side and to monitor the fuel balance.The FDR recorded the right engine throttle was reduced about two minutes after airborne and further reduced about two minutes later. About 8 minutes after takeoff, the right engine was shut down and the PACK switch turned to off position.During the approach, after established on localizer ILS Runway 24, the fuel imbalance was 1,000 lbs, which was the maximum imbalance fuel according to the aircraft limitation described in the FCOM.The delay of the throttle reduction, switching off the PACK switch, and fuel imbalance up to the maximum limitation indicated that the QRH procedure did not executed properly.Therefore, the KNKT recommends the Trigana Air Service to ensure pilot execute QRH procedure properly.
