Here’s a detailed Aircraft Walk-Around Inspection Checklist that can be tailored for most aircraft types, including general aviation and commercial jets:

1. Preliminary Steps

• Documentation Review:
  
  

  • Check the aircraft technical log for recent issues or deferred maintenance items.

  • Ensure compliance with MEL (Minimum Equipment List) requirements.

• Tools and Equipment:
  
  

  • Carry a flashlight, inspection mirror, and a checklist.

  • Verify personal safety gear, such as reflective vests, is in place.

• General Overview:
  
  

  • Conduct a visual inspection from a distance to identify obvious abnormalities like leaks or structural damage.

2. Walk-Around Inspection (Systematic by Zone)

Nose Section

• Radome:
  
  

  • Inspect for dents, cracks, or evidence of bird strikes.

  • Check fasteners and seals for integrity.

• Windshields and Wipers:
  
  

  • Verify wipers are intact and windshields are free of cracks or delamination.

• Pitot-Static Probes and Sensors:
  
  

  • Ensure pitot tubes, static ports, and angle-of-attack (AOA) sensors are clean, unobstructed, and undamaged.

• Nose Gear:
  
  

  • Inspect tires for wear, cuts, or bulges.

  • Check shock strut for proper extension and absence of leaks.

  • Verify doors are aligned, and taxi/landing lights are intact.

Left Wing

• Leading Edge:
  
  

  • Check for dents, scratches, or ice accumulation (if applicable).

  • Inspect slats and de-icing mechanisms.

• Wing Surfaces:
  
  

  • Look for structural damage, such as cracks or delamination.

• Fuel Tank Area:
  
  

  • Inspect for leaks or fuel stains near access panels and under the wing.

• Navigation and Strobe Lights:
  
  

  • Verify lenses are intact and clean.

• Static Dischargers:
  
  

  • Ensure all static wicks are present and undamaged.

Engine (Left Side)

• Inlet:
  
  

  • Check for foreign object debris (FOD), bird strikes, or visible damage to fan blades.

• Fan Blades:
  
  

  • Inspect for cracks, nicks, or deformation.

• Cowling:
  
  

  • Verify panels are secure, free of dents, and undamaged.

• Exhaust:
  
  

  • Look for signs of discoloration, cracks, or oil leaks.

Fuselage (Left Side)

• Passenger and Cargo Doors:
  
  

  • Ensure all doors are securely closed with seals intact.

• Windows:
  
  

  • Check for cracks or delamination.

• Fuselage Surface:
  
  

  • Look for dents, scratches, or signs of corrosion.

Tail Section (Empennage)

• Horizontal and Vertical Stabilizers:
  
  

  • Inspect for damage, dents, or scratches.

• Rudder and Elevator:
  
  

  • Verify freedom of movement and no structural defects.

• APU (Auxiliary Power Unit):
  
  

  • Inspect the exhaust area for signs of leaks or discoloration.

• Tail Lights:
  
  

  • Confirm that lights are intact and functional.

Right Wing

• Repeat the checks performed on the left wing:

  • Leading edge, surfaces, fuel tank area, lights, and static dischargers.

Engine (Right Side)

• Repeat the checks performed on the left engine:

  • Inlet, fan blades, cowling, and exhaust.

Right Main Landing Gear

• Tires:
  
  

  • Inspect for wear, cuts, bulges, or proper inflation.

• Shock Strut:
  
  

  • Verify proper extension and no fluid leaks.

• Brakes:
  
  

  • Check for signs of wear or hydraulic fluid leaks.

• Gear Doors:
  
  

  • Inspect for alignment and absence of cracks or dents.

Undercarriage and Underside

• Belly Drain Masts:
  
  

  • Check for blockages or signs of leakage.

• Hydraulic and Fuel Leaks:
  
  

  • Look for stains or puddles under the fuselage and wings.

• Antennas:
  
  

  • Verify alignment and check for damage or loose fittings.

3. Final Checks

• Surroundings:
  
  

  • Ensure no FOD or debris is near the aircraft.

• Environment:
  
  

  • Account for weather conditions that might affect your inspection, like ice or rain.

• Overall Aircraft:
  
  

  • Perform a final scan from a distance to ensure nothing was missed.

Best Practices

1. Time Management:

   • Allow adequate time to perform a thorough inspection without rushing.

2. Attention to Detail:

   • Focus on areas prone to wear or frequent issues (e.g., tires, sensors, and engine inlets).

3. Report Issues Immediately:

   • Log any defects in the technical log and notify maintenance personnel.

This checklist ensures a comprehensive inspection, enhancing aircraft safety and operational reliability.
