Show answer & explanationAnswer & explanation
Correct answer: B. Secure the crank handle in its bracket to prevent it from swinging loose during transit.
The crank handle, if not secured, can swing loose during transit, potentially striking other vehicles, pedestrians, or causing damage to the trailer itself. Securing it in its bracket is a standard pre-trip procedure.
Why the other options are wrong
- A. Lowering the landing gear is unnecessary and could create a different hazard if not fully retracted for travel.
- C. An unsecured handle is a hazard, even if the landing gear is retracted.
- D. Tying with rope is a temporary fix and not the proper securement method; the bracket is designed for this purpose.
Landing Gear Crank Handle Securement
The landing gear crank handle must be properly secured in its bracket after the landing gear is fully retracted to prevent it from swinging loose during vehicle operation.
- An unsecured handle can cause damage or injury.
- It's a standard pre-trip inspection item.
- The bracket is the designated securement point.
Memory trick: Crank's loose? Lock it or lose it!
