Plain English Summary

2/10 complexity

Pacific Aerospace CT/4, CT/4A and CT/4B aeroplanes (S/N 001–077 and 097–114) must have their fuel quantity indicators recalibrated and a cockpit placard installed (per PACSB/CT/117 Rev 1) by 31 December 1999. Owners/operators pay and schedule the work. The directive ensures the gauge reads only usable fuel and gives pilots a clear warning when the indicator shows zero, reducing risk of misreading remaining unusable fuel.
