FAA Takes Type Club, EAA/VAA Recommendations
Issues AMOC For Taylorcraft Wing Struts
November 14, 2007 — The FAA embraced the recommendations of EAA, the Vintage Aircraft Association, and type clubs including the Taylorcraft Foundation last week by approving the use of radiograph (x-ray) to inspect for internal corrosion on T-Craft A, B, and F series steel wing struts. The Airplane Certification Office (ADW-150) issued the Alternative Method of Compliance (AMOC) for Airworthiness Directive 2007-16-14 on November 8.
Originally, the FAA specified that owners use the eddy current or ultrasonic non-destructive testing (NDT) methods to comply with the AD. As a result, many affected owner-operators provided feedback to the FAA and both EAA and VAA regarding the corrosion issue. VAA Executive Director H.G. Frautschy and EAA's industry & regulatory affairs staff gathered the public feedback, contacted the FAA engineer responsible for the AD, and conducted independent research before crafting comments that were submitted in early October.
Some of the comments submitted by EAA/VAA were incorporated in the AMOC. The AMOC provides for the following:
- Allows the use of radiograph as a method of compliance for paragraphs (e)(2) and (e)(3) of AD 2007-16-14 using Taylorcraft Aviation, LLC Service Bulletin 2007-001, Revision B, dated October 15, 2007.
- Allows you to extend the initial inspection time in paragraph (e)(2)(B) from 24 months to 48 months if new vented struts are installed.
- Allow you to extend the repetitive inspection time in (e)(3)(A) from 24 months to 48 months for those that did the initial inspection using radiograph or ultrasonic. If the initial inspection was done using eddy current, then the 24-month interval must be adhered to.
- Allows for Univair Part Number UA-A815 and UA-A854 sealed struts as terminating action for the inspection requirements of AD 2007-16-14 for Taylorcraft Models BC-12-D/D1 and BCS12-D/D1 airplanes.
- This alternative method of compliance applies to all airplanes affected by AD 2007-16-14.
- Before using this approved AMOC on any airplane to which the AMOC applies, notify your appropriate Principal Inspector (PI) in the FAA Flight Standards District Office (FSDO) or lacking a PI, your local FSDO.
