This AD was prompted by reports indicating that brake fuses of the hydraulic quantity limiter of the main landing gear (MLG) have failed. We are issuing this AD to prevent loss of both hydraulic and brake systems if one fuse on each hydraulic system were to fail simultaneously, and consequent reduced controllability of the airplane.
