HYDRAULIC SHOP OPERATIONS
General Shop Rules. The practices and procedures described in this chapter pertain to the manufacturing and
repair functions of aviation activities and are applicable to all levels of maintenance. Because of the many types of Army
aircraft, each shop within the manufacturing and repair section must, of necessity, have personnel trained in general
practices and procedures to the extent that different types and model aircraft do not upset a smooth running shop.
Responsibility. All supervisory personnel in the manufacturing section are responsible for a continuing and
effective shop safety program. To implement and maintain this program, shop supervisors will utilize bulletin boards,
signs, and any other effective method. Shop personnel will cooperate in the shop safety program by making helpful
recommendations, and continually exercising care and caution in the operation of all shop equipment. All shop
personnel will strive to improve the safety program and be especially alert to observe and correct hazardous conditions
and unsafe shop practices. All accidents, no matter how minor, shall be reported to the shop supervisor, and all
published instructions regarding safety shall be strictly adhered to. Also, safety engineers and safety officers will ensure
that proper safety procedures are adhered to in accordance with AR 385-10, The Army Safety Program; AR 385-30,
Safety Color Code Markings and Signs, AR-385-32, Protective Clothing and Equipment; The Occupational Safety and
Health Act of 1971, OSHA 1910.251; all applicable fire codes, NFPA 410, and other accepted civilian and military safety
Shop Housekeeping. Housekeeping is the yardstick by which the shops in the manufacturing section are
judged. A clean, well arranged shop is a safe shop and reflects credit on all personnel concerned with its operation. The
following shop practices shall be observed:
Oil pans or drip pans shall be used where leaking oil, grease, and similar materials may cause
hazardous accumulations on equipment or floors. All spills shall be cleaned up immediately. Approved sweeping
compound may be used to remove these materials from the floor.
Floors shall not be cleaned with volatile or flammable liquids.
Floors shall be maintained smooth and clean, free of all obstructions and slippery substances. Holes
and irregularities in floors shall be repaired to maintain a level surface free from tripping hazards.
All unnecessary materials on walls shall be removed and projections shall be kept to a minimum.
Aisles shall be clearly defined and kept free of hazardous obstructions. Where possible, aisles shall be
suitably marked by painting.
All machines, work benches, aisles, etc, shall be adequately illuminated.
Some units that you will disassemble are made up of small parts that can easily be lost, broken, or
mixed with other parts. A unit Improperly reassembled or one reassembled with defective parts is the starting place for
an aircraft accident.
Wornout parts should be disposed of through the proper supply channels and never placed on the floor
where they can become dangerous or forgotten.
After servicing equipment with hydraulic fluid, MIL-H-5606 or MIL-H-83282, any oil remaining in can
which cannot be used immediately shall be sealed and moved to storage area for flammable materials.
Containers of hydraulic fluid which have been accidently left unsealed shall be considered
contaminated and shall be destroyed.
Shop Safety. Unsafe equipment and fire hazards are the main factors to be observed while planning safety
