Transportation Department, Federal Aviation Administration
We propose to supersede an existing airworthiness directive (AD) that applies to Univair Aircraft Corporation Models (ERCO) 415-C, 415-CD, 415-D, E, G; (Forney) F-1 and F-1A; (Alon) A-2 and A2-A; and (Mooney) M10 Airplanes. The existing AD currently requires an inspection of the aileron balance assembly and ailerons for cracks and excessive looseness of associated parts with the required repair or replacement of defective parts as necessary. Since we issued that AD, we received a report of a Univair Aircraft Corporation Model ERCO 415-D Ercoupe that crashed after an in-flight breakup due to possible aileron flutter. This proposed AD would add airplanes to the Applicability section and require inspections of the ailerons, inspections of the aileron balance assembly and aileron rigging for looseness or wear with a required repair or replacement of parts as necessary, and a reporting of the inspection results. We are issuing this proposed AD to prevent failure of the aileron assembly and associated parts, which could result in loss of control.
