Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all MORAVAN a.s. (Moravan) Model Z-242L airplanes. This proposed AD would establish a technical service life for these airplanes by restricting Acrobatic and Utility category operations and requiring replacement of the wings after a certain operational time period. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the Czech Republic. The actions specified by this proposed AD are intended to prevent structural failure of the wing due to fatigue cracking. Such failure could result in a wing separating from the airplane with consequent loss of airplane control.
