Plain English Summary

2/10 complexity

Owners and operators of Beechcraft 200 (Super King Air) must perform targeted maintenance on wing nacelle fuel probes and tanks to remove water/contaminants that can make gauges read falsely high. The procedure (remove, clean, drain/flush, reinstall and verify) corrects dangerous false-fuel indications that can cause fuel starvation.

Initial compliance is time/flight-hour based, with repeat maintenance every 2,000 flight hours or 12 months.

Background: It has been found that water contamination of the nacelle fuel tank quantity probes will cause a high indication, even with empty tanks.
