  2. Buse tire dollies or similar devices.
  3. Clift the tire with two people by its bead.
Show the answer and explanation

Correct answer: B. use tire dollies or similar devices.

  • A — incorrect The handbook calls for mechanical handling devices, not manual lifting of heavy tires.
  • B — correct The handbook notes that many compressed-gas accidents occur during tire mounting and directs the use of tire dollies and other appropriate devices to mount or remove heavy tires.
  • C — incorrect Two-person manual lifting is not the method given; tire dollies and appropriate devices are to be used.

BACKGROUND

The handbook's compressed-gas safety list notes that many accidents involving compressed gases occur during aircraft tire mounting. To prevent personal injury, tire dollies and other appropriate devices are used to mount or remove heavy aircraft tires. Related rules cover inflation: always use tire cage guards when inflating tires on any type of aircraft wheel, use pressure regulators on high-pressure air bottles to prevent over inflation, and note that tire cages are not required when adjusting the pressure of tires already installed on an aircraft.

STUDY TIP

Associate heavy tire handling with dollies and lifting devices, and tire inflation off the aircraft with cage guards.

KEY POINTS

  • Use tire dollies and appropriate devices to mount or remove heavy tires.
  • Always use a tire cage guard when inflating a tire on a wheel.
  • A cage is not required when adjusting pressure in tires installed on the aircraft.
