Required Actions
Conduct repetitive eddy current inspections of the left-hand and right-hand flanges and finger strips at rib 5.0 of the vertical stabilizer to detect fatigue cracking and repair if necessary. Install a steel reinforcement in the torsion box at rib 5.0 and cold-expand certain bolt holes on the torsion box.
