Day 8-9 Progress Check 2: Wheels Flashcards
What is the main benefit of regularly inspecting wheel bearings and tie bolts?
To prevent failures that could lead to wheel damage
What should be done if wheel bearings show signs of corrosion or false brinelling during inspection?
Reject the bearings and replace them
Which type of inspection requires the removal of the aircraft tire to check for cracks and corrosion?
Off-aircraft inspection
Which solvent is commonly used for cleaning aircraft wheel bearings?
Varsol, naptha, or Stoddard® solvent
What component in the inboard wheel half is designed to prevent wheel explosions due to overheating?
Thermal plugs
What are signs that wheel bearings need to be rejected during inspection?
Brinelling, galling, or spalling
What maintenance task must be performed to ensure wheel balance after cleaning or maintenance?
Reinstall the original balance weights
What is the purpose of balance weights in aircraft wheels?
To ensure the wheel is statically balanced
What type of inspection is used to check tie bolts in the aircraft wheels for cracks?
Magnetic particle inspection
What should be avoided when cleaning wheel bearings to prevent damage?
Using compressed air to dry bearings while rotating them
Why is it important to deflate the tire before removing the wheel during an off-aircraft inspection?
To prevent a catastrophic failure due to residual pressure
What material are most modern aircraft wheels made from?
Aluminum or magnesium alloy
What is the primary function of aircraft wheels?
To support the entire aircraft weight during taxi, takeoff, and landing
Why is it important to check fusible plugs for signs of melting or deformation?
To detect signs of excessive temperatures in the wheels
What is the purpose of the two-piece construction design in aircraft wheels?
To allow easier tire mounting and maintenance
