The Brazilian regulator Agência Nacional de Aviação Civil (ANAC) issued an Emergency Airworthiness Directive (EAD) to inspect barrel nuts in the horizontal stabilizer-to-vertical stabilizer attachment joint on Embraer EMB-500 Phenom jets.

During an inspection on the assembly line, cracking in the barrel nuts at the horizontal stabilizer-to-vertical stabilizer attachment joint was found on an Embraer Phenom jet.

This prompted ANAC to issue an EAD to detect and correct cracking of the barrel nuts at the horizontal stabilizer-to-vertical stabilizer attachment joint, which could result in reduced structural integrity of the affected part and consequent detachment of the horizontal stabilizer from the airplane.

The inspection must be accomplished within three flight cycles of July 25, 2014.
