  • Parking Your Scott/ABW Tailwheels

    If your plane has a Scott 3200 or its ABW equivalent tailwheel, when it is in its locked state, a spring rests in a pair of notches on either side of the steering arm assembly (circled in red) keeping the steering arm engaged with the wheel fork. When the tailwheel reaches the end of its locked swivel range, a pawl (outlined in blue and in the second photo), which has a rounded inside edge, presses in on the spring, pushing it inward toward the center of the pivot point. This unlatches the lock in that direction, allowing the tailwheel to swivel freely.

    When you’re positioning your plane on the ground, it’s not uncommon to push the plane backwards into position. This usually unlocks the tailwheel and it swivels around in reverse while you’re moving it. Be sure, however, to straighten the tailwheel and move it back to its locked position when you have reached your final parking spot. Extended periods of time in the unlocked position will cause a set in the lock spring and it won’t fully spring back into the locked position.

    Having a locking tailwheel come unlocked on landing or taxi during a heavy crosswind can lead to a RLOC situation, and that’s no fun!

    Chris, although I do not have that type tailwheel, good info and thanks for sharing. It's late in the day here and a HOT 92 degrees on the hill, which is causing my brain to not work as well---but what the heck is RLOC?? If it's not any fun, then I want to avoid it, but I don't know what "it" is. ;-)
