## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Fokker Model F28 Mark 0100 series airplanes. This proposal would require inspection(s) to verify that the position indicator of the fuel balance transfer valve (FBTV) is in the closed position, and closing the FBTV, if necessary; and deactivation of the fuel balance transfer system (FBTS). This proposal is prompted by a report that, under certain failure conditions, the actuator of the FBTV could remain in the open position without a flight deck indication. The actions specified by the proposed AD are intended to ensure that the FBTV is not in the open position during flight, which could lead to the reduction of fuel supply to the engines during cross-feed operation and consequent engine fuel starvation.
