Airworthiness Directives; Univair Aircraft Corporation Airplanes

What this AD requires

We are superseding an existing airworthiness directive (AD) for certain 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. That 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. This new AD would add airplanes to the Applicability section; require inspections of the ailerons, aileron balance assembly, and aileron rigging for looseness or wear, require repair or replacement of parts as necessary; and require a report of the inspection results. This new AD was prompted by a report of a Univair Aircraft Corporation Model ERCO 415-D Ercoupe that crashed after an in-flight breakup due to possible aileron flutter. We are issuing this AD to correct the unsafe condition on these products.

Models originally manufactured/marketed as (ERCO) 415-C/-CD/-D/-E/-G, (Forney) F-1/F-1A, (Alon) A-2/A2-A, and (Mooney) M10, per the AD text; applies to all serial numbers, certificated in any category.

Whether AD 2012-08-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2012-08-06 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
