When inspecting the landing gear during a pre-trip inspection of a combination vehicle, what should you check?
- A.That it raises and lowers smoothly in both gear ranges, the legs and cross members are undamaged, the shoes are present and secure, and the handle is stowed
- B.Only that the crank handle is painted the same color as the trailer
- C.That the legs are left fully extended while driving to keep the trailer level
- D.That the gear oil inside the legs is changed every trip
Correct answer
A. That it raises and lowers smoothly in both gear ranges, the legs and cross members are undamaged, the shoes are present and secure, and the handle is stowed
Why
Landing gear takes the trailer's full nose weight whenever it is uncoupled, so bent legs, a binding gearbox, or a missing shoe can drop a loaded trailer. Running it through both ranges during the inspection also proves it will work when you actually need to drop or hook the trailer.
