Abstract: A tow bar adapted to be coupled to a steerable nose wheel assembly of an aircraft. The tow bar includes an arm assembly having a handle at a first end thereof and an oppositely-disposed second end. First and second arms are pivotally coupled at first ends thereof to the arm assembly to enable oppositely-disposed second ends of the first and second arms to pivot toward and away from each other. Engagement members are disposed at the second ends of the first and second arms, and each engagement member is adapted to engage a portion of the steerable nose wheel assembly. A mechanism is provided for locking the first and second arms to prevent their pivoting relative to each other.
