| 2011-7878 | Airworthiness Directives; Burl A. Rogers (Type Certificate Previously Held by William Brad Mitchell and Aeronca, Inc.) Models 15AC and S15AC Airplanes | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require repetitive inspections of the upper and lower main wing spar cap angles for cracks and/or corrosion and installing inspection access panels. This AD would also require replacing the wing spar cap angles if moderate or severe corrosion is found and applying corrosion inhibitor. This proposed AD was prompted by reports of intergranular exfoliation and corrosion of the upper and/or lower wing main spar cap angles found on the affected airplanes. We are proposing this AD to detect and correct cracks, intergranular exfoliation and corrosion in the wing main spar cap angles, which could result in reduced strength of the wing spar and the load carrying capacity of the wing. This could lead to wing failure and consequent loss of control. | 2011-04-04 | 2011 | 4 | https://www.federalregister.gov/documents/2011/04/04/2011-7878/airworthiness-directives-burl-a-rogers-type-certificate-previously-held-by-william-brad-mitchell-and | https://www.govinfo.gov/content/pkg/FR-2011-04-04/pdf/2011-7878.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for the products listed above.
