Airworthiness Directive · Amendment 39-18335 · Stabilizers
SOCATA Airplanes
This AD applies to SOCATA Models TB 9, TB 10, TB 20, TB 21, and TB 200 airplanes, all manufacturer serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for SOCATA Model TB 9, TB 10, TB 20, TB 21, and TB 200 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as corrosion of the horizontal stabilizer. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the actions in paragraphs (f)(1) through (f)(5) of this AD:
(1) Within 13 months after January 4, 2016 (the effective date of this AD) and repetitively thereafter at intervals not to exceed 72 months, do a special detailed inspection of the HS spar following the instructions of DAHER-SOCATA TB Aircraft Mandatory Service Bulletin SB 10-152, Amendment 1, dated April 2015.
(2) If no discrepancy is detected during any inspections required by paragraph (f)(1) of this AD, protect the HS spar following the instructions of DAHER-SOCATA TB Aircraft Mandatory Service Bulletin SB 10-152, Amendment 1, dated April 2015.
(3) If any discrepancy is detected during any inspection required by paragraph (f)(1) of this AD, before further flight, do the applicable corrective action(s) following the instructions of DAHER-SOCATA TB Aircraft Mandatory Service Bulletin SB 10-152, Amendment 1, dated April 2015.
(4) Accomplishment of protection or corrective actions on an airplane as required by paragraph (f)(2) or (f)(3) of this AD, as applicable, does not constitute terminating action for the repetitive inspections as required by paragraph (f)(1) of this AD for that airplane.
(5) Inspections and corrective actions on an airplane done before January 4, 2016 (the effective date of this AD) following the instructions of DAHER-SOCATA TB Aircraft Recommended Service Bulletin SB 10-152, dated May 2013, are acceptable to comply with the requirements of this AD for that airplane. After January 4, 2016 (the effective date of this AD), repetitive inspections and applicable corrective actions, as required by this AD, must be done as required by paragraph (f)(1) of this AD following the instructions of DAHER-SOCATA TB Aircraft Mandatory Service Bulletin SB 10-152, Amendment 1, dated April 2015.
