order to guard against the ever present dangers of static elec-

tricity, all aircraft must be effsctlvely groundedow resistant ground wire at all times and should be removed only when it is necessary to move the aircraft. Prior to applying all external electrical power, eachpower unit should be independently grounded.

It is the responsibility' of all maintenance personnel to conscientiously adhere to and follow preventive procedures and policies to eliminate ingestion of forslgn objects by gas turbina engines. Several areas of concern are parking and storage areas, maintenance areas and procedures, engine installation and engine ground operation. Frequent and periodic inspection of engine nacelles, inlet ducts and storage areas Is recommended. When required, careful cleaning of areas should be accomplished. All maintenance personnel must exercise extreme care while performing maintenance procedures In and around the aircraft to prevent foreign object damage to the two turbojet engines. The greater

-

of the engines creates greater auction pressures and moan larger auction areas. These higher suction pressures enable the engines to pull objects from greater distances into the Intake ducts or the engine

nacelle areae and on Into the engines' compresior sections. Objecta may be picked up from the deck areas or from other areas which ars directly or indirectly open to the engine nacelle and laiet duct. Therefore, it is mandatory that personnel performing maintenance in and around theaccount for all tools, hardware and components after all maintenance procedures and operations.

Duct plugs and dust excluders are required to reduce foreign object accumulation. (See. )

The burned area mayighly absorbent area for this compound; therefore, skin contact must be avoided. The inhalation of theseis extremely unlikely due to their pyrophoric characteristics; however, the fumes are toxic.

Personnel protective equipment must be worn at all times while doing any transfer, filling, Installation, removal or maintenance work with pyrophoric contaminated equipment. All handling and transfer operations must be controlled to prevent leakage and personnel exposure to liquid, gas and fires. All equipment must be thoroughly decontaminated by th* pyrophoric handlers before leaving their custodyontrol tag system shall be used showing the status of all equipment where residue could be trapped.

order to safely perform all maintenance functions requiring

removal of aircraft equipment and/or major removable components, in addition to towing orpecified ground handling gross weight and CG is required.

major removable component* and/or equipment are to be

removed from an aircraft fully fueled, this weight and CG condition will allow the maximum removal of such components and equipment without damage to the aircraft during ground handling.

major removable components and/or equipment are to be

removed from on aircraft at its zero fuel weight, this weight and CGwill allow the maximum removal of such components and equipment without damage to the aircraft during ground handling.

CAUTION

If the aircraft Is partially fueled there shell be more fuel weight forward of the landing gear than aft of the landing gear. Thecan then be handled with any configuration of component/equipment removal.
