## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to all Univair Aircraft Corporation (Univair) Alon A-2 and A2-A, ERCO 415-C, 415-CD, 415-D, E, and G, Forney F-1 and F-1A, and Mooney M10 airplanes. This proposed AD would require you to repetitively inspect the wing center section for evidence of corrosion by installing inspection openings or by the use of a scope and light source, e.g., fiberscope borescope or an endoscope, that meets specified criteria. This proposed AD would also require you to repair or replace any parts where corrosion or corrosion damage was found, install cover plates where inspection openings were made, and send inspection results to Federal Aviation Administration (FAA). This proposed AD is the result of several reports of corrosion being found throughout the wing center section structure. The actions specified by this proposed AD are intended to detect and correct corrosion in the wing center section which could result in failure of the wing center section structure during flight. Such failure could lead to loss of control of the airplane.
