## Abstract

We are removing AD 2012-02-18, which applied to all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2012-02-18 required revising the maintenance program to include revised airworthiness limitations. We issued AD 2012-02-18 to address cracking of the flap tracks, which could lead to flap asymmetry and loss of control of the airplane. Since we issued AD 2012-02-18, we have issued AD 2017-09-03 to address the unsafe condition. Accordingly, AD 2012-02-18 is removed.
