serious threat to flight safety. This program is an ongoing effort to control hydraulic fluid contamination. AIRCRAFT FUEL SURVEILLANCE PROGRAM Foreign contaminants and water in aircraft fuel systems constitute a major hazard in naval aircraft. Harmful effects of water, particulates, and microbiological growth include erratic or incorrect fuel quantity indications; icing of filters, valves, and other fuel system components; engine failure caused by carburetor/fuel control icing or malfunction; and jet engine starting difficulties. Further, if contamination remains undetected, rubber fuel cells deteriorate and become permanently damaged. Constant vigilance by maintenance personnel is required to ensure that clear, bright, and dry fuel is delivered to the aircraft, and subsequently to its engines. All aviation fuels are produced under rigidly controlled specifications. To maintain its high quality, maintenance personnel must take careful and continual measures to prevent contamination. Contamination can occur from fuel mixing with other bulk petroleum products as well as from dirt, rust, and water. Serious engine and airframe problems develop if inadequate attention and effort are given to maintaining fuel quality. Since no two fuel systems are identical, it is not possible to establish rigid and detailed procedures that will apply in all situations. The plane captain takes fuel samples from low-point drains of all fuel cells/tanks before the first flight of the day. This action is normally accomplished during the daily inspection. This also includes any auxiliary, external, or in-flight refueling tanks. Additional information on this program can be obtained in the Aircraft Refueling NATOPS Manual, NAVAIR 00-80T-109. Q34.

AVIATORS BREATHING OXYGEN (ABO) SURVEILLANCE PROGRAM Aviator’s breathing oxygen (ABO) comes in both gaseous and liquid states. Liquid oxygen (LOX) is converted to a gaseous state before its delivery to the aircrew. Because oxygen can be contaminated easily, LOX requires frequent and continual monitoring by personnel to ensure detection of contamination. The safety of the aircrew is of the utmost priority. An oxygen surveillance program is the primary method of ensuring that each operation in the LOX supply system is carried out in strict compliance with established procedures. Surveillance begins with procurement or generation of LOX and continues throughout storage, handling, transfer, and servicing in the aircraft. This program is also applicable to all naval activities involved in the support and manufacture of LOX and related equipment. Each person associated with the Aviation Breathing Oxygen Surveillance and Contamination Program should have a thorough knowledge of the characteristics of liquid oxygen and gaseous oxygen and the hazards of contamination. Each person should also know the quality standards listed in the ABO Surveillance Program Laboratory Manual and Field Guide, A6-332A0-GYD-000. EGRESS SYSTEM CHECKOUT PROGRAM The high-performance aircraft used by the Navy places extreme demands on emergency escape systems. These systems contain high-explosive devices that are designed for onetime use only. Actuation of these devices could result in severe injury or death to personnel and damage to or destruction of aircraft. Therefore, because of the inherent dangers associated with ejection seats and canopy systems, an egress systems checkout procedure is required. The egress/environmental work center (AME shop) indoctrinates all personnel in the hazards and safety precautions associated with these systems. A system checkout must be given by a qualified AME to all new maintenance personnel before they perform any aircraft maintenance work. Maintenance personnel must be checked out every 6 months thereafter before the last day of the requalification month. In addition, any personnel removed from aircraft maintenance responsibilities for more than 90 5-27
