## Abstract

We are adopting a new airworthiness directive (AD) to supersede AD 82-07-04, which applies to certain Allied Ag Cat Productions, Inc. (Ag Cat) G-164 series airplanes. AD 82-07-04 currently requires you to modify the fuel shut-off valve control by installing a new stop-plate. Since we issued AD 82-07-04, we have determined the need to add airplane models and serial numbers that were not previously included in the Applicability section. Consequently, this AD retains the actions of AD 82-07-04 and adds airplane models and serial numbers to the Applicability section. We are issuing this AD to prevent turning the fuel shut-off valve clockwise past the "ON" position stop which, if not corrected, could allow the fuel valve to be rotated to an unplacarded "OFF" position. This condition could lead to reduced fuel flow and consequent loss of engine power.
