                For fuel nozzles with a P/N listed in Table 4 of this AD, within 150 operating hours after 17 March 2005 (the effective date of the original issue of this AD), unless previously accomplished.

                2. Before further flight after the effective date of this AD.

                3. At the next fuel nozzle overhaul after the effective date of this Directive.

             This Amendment becomes effective on 28 September 2006.
Background:  This Directive required a onetime inspection of the fuel nozzle screen for contamination, and if contamination is found, inspection and cleaning of the entire aircraft fuel system before further flight.  This Directive also required replacing the fuel nozzle with a new design fuel nozzle.

             This Directive resulted from 10 reports of engine power loss with accompanying collapse of the fuel nozzle screen, due to fuel contamination.  This Directive was issued to minimize the risk of sudden loss of engine power and uncommanded shutdown of the engine due to fuel contamination and collapse of the screen in the fuel nozzle.

             This amendment is prompted by the discovery that several part numbers (P/Ns) of fuel nozzles were inadvertently left out of AD/AL 250/85.  That AD, as worded, allows certain P/N fuel nozzles back into service.  Those fuel nozzles must not be allowed back into service.  The intention of this AD is to minimize the risk of sudden loss of engine power and uncommanded shutdown of the engine due to fuel contamination and collapse of the screen in the fuel nozzle.

             The original issue of this AD became effective on 17 March 2005.
