AD 2005-18-23: Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes

(c) This AD applies to all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes; certificated in any category. Unsafe Condition (d) This AD was prompted by additional reports indicating that significant corrosion of the electrical connectors in the wheel well of the MLG has also been found on airplanes that land on runways treated with deicing fluids containing potassium acetate. We are issuing this AD to prevent corrosion and subsequent moisture ingress into the electrical connectors, which could result in an electrical short and consequent incorrect functioning of critical airplane systems essential to safe flight and landing of the airplane, including fire warning systems.
