CANCELLATION I REVISION: Not applicable. 

REASON: This EAD results from a report of cracking in the barrel nuts at the

This EAD is being issued to detect and correct cracking of the barrel nuts at the horizontal stabilizer-tovertical stabilizer attachment joint, which could result in reduced structural integrity of the affected part 

and consequent detachment of the horizontal stabilizer from the airplane. 

Since this condition may exist in other airplanes of the same type and affects flight 

safety, an immediate corrective action is required. Thus, suffic ient reason exists to request compliance 

with this EAD in the indicated time limit without prior notice. 

REQUIRED ACTION: You must inspect and replace the discrepant barre l nuts in 

the horizontal stabi I izer-to-vertical stabi I izer attachment joint.
