07 Jan Aircraft Maintenance Safety

Aircraft Maintenance Safety

Aircraft maintenance includes inspection, servicing, fabrication, and repair of aircraft structures, engines, coatings, and systems. Whether work is performed in a hangar, maintenance area, or on the flightline, employees may encounter moving aircraft, elevated work, rotating equipment, hazardous chemicals, noise, tools, and restricted workspaces. Staying alert and following established procedures protects both employees and aircraft.

Working Around Aircraft

Aircraft are large, and pilots or equipment operators may have limited visibility of employees working nearby. Maintain communication with aircraft operators and ground personnel, remain within designated work areas, and never enter restricted ramp or flightline areas without authorization.

Be alert for:

• Moving aircraft and ground-support equipment.
• Wings, tails, antennas, probes, and other protruding components.
• Hoses, cables, cords, and equipment that create trip hazards.
• Poorly illuminated areas.
• Aircraft tires and other potential pinch or crush points.

Never rush maintenance work. A steady, deliberate pace helps prevent injuries, equipment damage, and maintenance errors.

Propellers, Rotors and Engines

Treat propellers, rotors, engine intakes, exhaust areas, and other rotating components as serious hazards.

• Stay outside designated propeller and rotor hazard areas.
• Never assume an engine or rotating component cannot start unexpectedly.
• Keep loose clothing, jewelry, and long hair secured.
• Keep tools, rags, hardware, and debris away from engine intakes.
• Follow required energy-isolation procedures before servicing equipment that could move or start unexpectedly.

Good housekeeping is especially important because loose objects can become foreign object debris (FOD) and damage aircraft or become dangerous projectiles.

Working at Heights

Aircraft maintenance frequently requires ladders, platforms, scaffolds, or aerial lifts to reach elevated work areas.

Use the appropriate access equipment for the task, inspect it before use, and follow applicable fall-protection requirements. Never improvise with boxes, aircraft components, or other unsuitable objects to gain additional height.

Be especially careful when working on wings, fuselages, or other curved and potentially slippery aircraft surfaces.

Chemicals and Flammable Materials

Aircraft maintenance may involve fuels, lubricants, solvents, cleaners, paints, coatings, adhesives, and stripping chemicals. Review the Safety Data Sheet (SDS) and product instructions before using unfamiliar materials.

Use required ventilation and PPE, keep containers properly labeled and closed, and follow established storage and disposal procedures. Keep flames, smoking, sparks, and other ignition sources away from fuels, solvents, and other flammable materials.

Tools and Maintenance Tasks

Welding, drilling, riveting, grinding, sanding, and other maintenance activities introduce additional hazards. Inspect tools before use, use required guards and safety devices, and select the correct tool for the task.

When handling large or awkward aircraft components, use mechanical lifting equipment or get assistance rather than attempting an unsafe lift.

Wear the Right PPE

PPE should be selected for the specific maintenance task and hazards. Depending on the work, employees may need:

• Safety glasses, goggles, or face protection.
• Work gloves or chemical-resistant gloves.
• Protective footwear with slip-resistant soles.
• Hearing protection.
• Protective clothing or coveralls.
• Fall protection.
• Respiratory protection when required.

Remember

Aircraft maintenance requires attention to both worker safety and aircraft integrity. Stay clear of moving and rotating equipment, control FOD, use proper access equipment, understand chemical hazards, wear required PPE, and never sacrifice safety or quality to save time.
