During your pre-trip inspection, you notice that the trailer's landing gear crank handle is bent and difficult to operate, although the landing gear itself appears to be fully retracted. What is the most appropriate action before starting your trip?

  1. ASecure the bent handle in its stowed position and proceed with the trip.
  2. BLubricate the crank mechanism and attempt to straighten the handle.
  3. CReplace the damaged crank handle or have it repaired before departure.
  4. DUse a tool to force the handle into the stowed position and report for repair later.
Show answer & explanation

Correct answer: C. Replace the damaged crank handle or have it repaired before departure.

A bent or difficult-to-operate crank handle, even if the landing gear is retracted, is a defect. It could make uncoupling or future adjustments impossible or unsafe. Replacing or repairing it ensures proper and safe operation.

Why the other options are wrong

  • A. While secured, a damaged handle means you cannot safely operate the landing gear when needed.
  • B. Lubrication might help, but a bent handle needs proper repair or replacement, not just a temporary fix.
  • D. Forcing a damaged part can cause further damage and is unsafe. Delaying repairs on essential equipment is not advisable.

Landing Gear Inspection

The landing gear supports the trailer when it is uncoupled from the tractor. Its proper functioning, including the crank handle, is essential for safe coupling and uncoupling.

  • Must be fully raised and secured for travel.
  • Crank handle must be functional and stowed.
  • Check for bent, cracked, or damaged legs.
  • Ensures stability when trailer is detached.

Memory trick: A bent handle means a bent plan for your next stop.
