Paper Abstract

A naturally cracked aircraft stabilizer former has been examined. By using surface shear horizontal diagnostic acoustic waves and a multi-point detection approach, a fretting crack, 0.2-inch long, 0.03-inch deep and at 0.06-inch to a rivet hole has been clearly identified. The proposed approach provides a simple way to interpret sensor output without imposing demanding transducer performance requirements.
