date of this Directive, whichever occurs first.

             For Requirement 3 - Before further flight after the Requirement 2 inspection.
             This Airworthiness Directive becomes effective on 18 June 2008.
Background:  The ANAC has advised that one occurrence of a fuel booster pump circuit breaker opening during an engine maintenance servicing has been reported.  An inspection inside the fuel tank revealed the fuel booster pumps electrical harness chafing against its body, causing the loss of the electrical wiring protection and resulting in a short circuit.  Further in-tank inspections have showed other fuel booster pump electrical harnesses chafing either with the pump body and/or with adjacent fuel lines, causing damage to the harness protective layers and resulting on possible ignition source inside the fuel tank.
             This Directive requires temporary revision of the AFM, inspection of fuel booster pumps electrical harness installed on LH/RH tanks together with installation of clamps on tank structure and tie-raps to attach these electrical harnesses is.
