<strong>TO</strong> <strong>00</strong>-<strong>25</strong>-<strong>172</strong> 3.8 ADJACENT AIRCRAFT. <strong>Air</strong>craft parked as prescribed in AFH 32-1084 and which intrude into the fuel servicing safety zone shall not be: a. Involved in engine starts or engine trim operations. b. Radiating electromagnetic energy. c. Using NDI or welding equipment. d. Involved in any maintenance requiring: (1) Energizing or de-energizing external electrical circuits. (2) Disconnecting combustible fluid carrying lines, except those equipped with non-spill, quick disconnects. e. Moved under its own power. NOTE However, normal maintenance, including pre/postflight inspections involving internal aircraft electrical power, may be performed on adjacent aircraft providing there are no spilled flammable liquids. 3.9 SERVICING CONSTRAINTS. The following constraints apply during servicing operations: a. During servicing, only those personnel actually required for the operation shall remain in the fuel servicing safety zone. <strong>Air</strong>crew on commercial contract cargoonly aircraft may remain on board the aircraft during servicing operations. <strong>Air</strong>crews on MAF aircraft may remain on board the aircraft during servicing operations. Passengers may remain on MAF aircraft as long as the provisions of Chapter 5 are met. Personnel receiving training on specific tasks required to complete the fuel servicing operation are allowed in the FSSZ if they are under the direct control and supervision of the fuel servicing supervisor. Quality inspectors may enter the FSSZ to perform quality assurance functions. Personnel performing authorized functions on adjacent aircraft, which intrude into the FSSZ, may remain on duty with the adjacent aircraft. The servicing supervisor will coordinate with all affected personnel so that these restrictions are observed. There shall be no smoking within 50 feet of any aircraft or servicing operation. Servicing operations shall not begin if any indication of “hot brakes” are noted. b. <strong>Air</strong>craft radar and High Frequency (HF) radios shall not be operated in the transmit mode within 3<strong>00</strong> feet of servicing operations, unless otherwise specified in the applicable aircraft and equipment repair technical orders, or when <strong>TO</strong> 31Z-10-4 procedures are used to ensure a safe distance. Satellite communications (SAT- COM) radios may be operated in the transmit mode if the antenna beam is pointed at least ten degrees above the horizon. c. Do not start servicing operations (any movement of fuel, water, environmental fluid, oil, hydraulic fluid, oxygen, nitrogen, or hydrazine) whenever one of the following conditions exists. If servicing operations are already in progress, terminate as soon as practical: (1) When a lightning advisory has been issued indicating an electrical storm is within five nautical miles (5.75 miles) of the servicing area. (2) Winds reach velocities hazardous to the aircraft or servicing operations. Specific high wind restrictions will be developed by base-level personnel for each base supporting a flying mission. (3) Fire in the vicinity is generating hot ashes. (4) In those cases where on-scene fire protection is required, if an aircraft crash/fire occurs at the same airfield, servicing operations already underway will be stopped and fuel servicing equipment will be disconnected. No new servicing operations will be started until the crash/fire is declared under control by the base Fire Chief or Senior Fire Officer (SFO), his designated representative, or the on-scene commander, and the required level of fire protection is available to support servicing operations. (5) In those cases where on-scene fire protection is required, in the event of an In-Flight Emergency (IFE) or crash warning resulting in the departure of the on-scene fire vehicle, servicing operations already underway must be stopped. No new servicing operations may be started without the concurrence of the base Fire Chief, his designated representative, or the on-scene commander, or until the IFE or crash warning has been cancelled. As a condition of continuance during IFEs, either an operational fixed, skid mounted, or portable Aqueous Film Forming Foam (AFFF) fire suppression system discharging through oscillating nozzles or at least one fully manned aircraft rescue and fire fighting vehicle must be positioned at the aircraft fuel servicing scene. 3-5
