## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-30F (KC- 10A and KDC-10), DC-10-40F, MD-10-10F, and MD-10-30F airplanes; and Model MD-11 and MD-11F airplanes. This proposed AD would require installation of control cable freeze protection by making certain changes. This proposed AD results from reports of standing water on the horizontal pressure panel above the main and center landing gear wheel wells. We are proposing this AD to prevent the accumulation of ice on the flight control cables in the wheel wells. When the landing gear doors open or vibration in this area occurs, such ice accumulation could break off and can cause injury to people or damage to property on the ground, can affect landing gear controls and rear spar flight control systems, can cause damage to other control systems, and might cause loss of control of the airplane.
