Caravan Landing Gear, Brakes & Steering
Explore the named components, make a prediction, then connect the supplied result to the system. This workshop adds coached practice alongside the course handbook and assessed lab.
Caravan support, brake release and steering
Follow the fixed gear's load path, the two pedal-driven brake circuits and the mechanical nose-steering linkage. Compare a command with the particular force or motion it can actually transmit.
Pedal steering and toe braking are separate inputs; hydraulic return and structural load paths have their own physical connections.
Recorded state: before the supplied change
Green outlines identify components named in the selected exercise record; they do not indicate a healthy component.
Named connections and what each arrow means
- Rudder-pedal and toe inputs → Brake reservoir and master cylindersPhysical relationship: Brake-pedal displacement
- Brake reservoir and master cylinders → Parking valve and return passagesPhysical relationship: Separate left / right pressure and release paths
- Parking valve and return passages → Wheel brake, disc and bearingsPhysical relationship: Side-specific wheel-brake pressure / return
- Rudder-pedal and toe inputs → Steering tube, bungee and bellcrankPhysical relationship: Rudder-pedal torque-arm movement
- Steering tube, bungee and bellcrank → Spring gear, nose snubber and damperPhysical relationship: Bellcrank turns the nose assembly
- Wheel brake, disc and bearings → Spring gear, nose snubber and damperPhysical relationship: Wheel loads and brake reaction into gear structure
Rudder-pedal and toe inputs
Provide distinct mechanical inputs for steering and brake application.
Supplied record: No steering / brake command
How it works with the rest
Rudder-pedal shaft movement reaches the steering torque arms and tube/bungee. Brake-pedal movement operates the brake master cylinders. A command in one function does not prove that the other function moved. The brake operational check includes pilot and copilot positions, but the specific physical task and configuration govern its setup.
What the evidence must show
Name steering-shaft movement separately from an applied or released brake pedal. Do not infer either output from foot position alone.
Selected: Rudder-pedal and toe inputs
Follow the change through the system.
Fictional Caravan concept trainer: a serviceable drag-link spring and oil-snubber nose strut receive two vertical load pulses with the same peak force. The second pulse reaches that peak more rapidly. The trainer supplies relative reaction shares rather than aircraft forces, dimensions or acceptance criteria. Steering is centered, no pedal or toe-brake command is applied, and no side-to-side oscillation is introduced.
Before the recorded change
Slow-rise vertical pulse: the drag-link spring carries the greater share; the oil snubber contributes a smaller share. All represented support parts are serviceable.

Course applicability and study references
Formative supplement to TM-033 Rev E using the supplied Cessna Model 208 D2078 Revision 42 compilation, Chapter 32. Covers the described landplane system; wheel/brake modifications and float installations require their own applicable information. All records are fictional trainer observations. They introduce no aircraft load, pressure, timing or wear limit and are not physical maintenance instructions. Existing assessed work and completion requirements remain separate.
