Requires inspection of the routing of hydraulic systems No. 1 (left-hand side) and No. 2 (right-hand side) engine-driven pump pressure hoses over the length for any damage and for minimum clearance between the engine-driven pump hydraulic pressure hose and case drain, suction pressure hose and surrounding pylon structure. The hydraulic system-driven pump hoses must be replaced if damaged and/or adjusted to meet the minimum clearance requirements. This AD is prompted by in-service reports of the hydraulic systems engine-driven pump pressure hydraulic hoses chafing against the pylon in the aft equipment bay. This condition could lead to hydraulic system leaks and failures, which can result in the loss of the affected hydraulic system.
