## Abstract

We are adopting a new airworthiness directive (AD) for all Augustair, Inc. Models 2150, 2150A, and 2180 airplanes. This AD requires you to inspect the vertical stabilizer front spar for cracks and loose fasteners, repair any cracks and loose fasteners found, and reinforce the vertical stabilizer spar regardless if cracks are found. This AD results from six reports of airplanes with a cracked vertical stabilizer front spar. We are issuing this AD to detect and correct cracks in the vertical stabilizer front spar, which could result in separation of the vertical stabilizer from the airplane. This failure could lead to loss of control.
