with a serviceable valve, P/N 10-3200-1, 10-3200- 2, or a valve identified in paragraph 3.I. of the Accomplishment Instructions of the service bulletin, and do a hydraulic supply (fire) shutoff valve test, in accordance with paragraph 3.J. of the Accomplishment Instructions of Boeing ASB 747-29A2102.

            Note: FAA AD 2003-26-13 Amdt 39-13412 refers.

            Compliance: For Requirement 1 and 2: Unless previously accomplished, within 6 months after the effective date of this Directive.

            For Requirement 3: At intervals not to exceed 6 months, until the actions specified by Requirement 5 of this Directive have been accomplished.

            For Requirement 4: Before further flight.

            For Requirement 5: Within 4 years from the time the discrepant valve is identified as detailed in Requirement 1 of this Directive.

            This Airworthiness Directive becomes effective on 15 April 2004.

            Background: This Directive requires identification of the valves installed on the engine struts as hydraulic supply (fire) shutoff valves for the engine-driven pump, repetitive tests if necessary, and eventual replacement of discrepant valves. This action is necessary to prevent leakage of hydraulic (flammable) fluid into an engine fire, which could result in an uncontrolled fire. This action is intended to address the identified unsafe condition.
