## Abstract

We are adopting a new airworthiness directive (AD) for certain WACO Classic Aircraft Corporation Models 2T-1A, 2T-1A-1, and 2T-1A-2 airplanes. This AD requires inspection of the front and rear horizontal stabilizer spar assemblies with replacement of parts as necessary. This AD was prompted by cracking of the horizontal stabilizer spars, which could lead to failure of the horizontal spars with consequent loss of control. We are issuing this AD to correct the unsafe condition on these products.
