## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all EMBRAER Model EMB-110P1 and EMB-110P2 airplanes. This proposed AD would require repetitive inspections for corrosion or cracking of the rotating cylinder assembly in the nose landing gear (NLG), and related investigative/corrective actions if necessary. This proposed AD would also require the eventual replacement of the rotating cylinder assembly with a new part, which terminates the need for the repetitive inspections. This proposed AD is prompted by reports of corrosion on the NLG rotating cylinder assembly. We are proposing this AD to prevent cracks from emanating from corrosion pits in the NLG rotating cylinder assembly, which could result in failure of the NLG.
