AD 2020-21-22 Requires Inspecting The Tailcone And Horizontal Stabilizer For Corrosion And Cracks
The FAA is adopting a new airworthiness directive (AD) for all Textron Aviation Inc. (Textron) Models 180, 180A, 180B, 180C, 180D, 180E, 180F, 180G, 180H, 180J, 180K, 182, 182A, 182B, 182C, 182D, 185, 185A, 185B, 185C, 185D, 185E, A185E, and A185F airplanes.
This AD was prompted by a report of cracks found in the tailcone and horizontal stabilizer attachment structure. This AD requires inspecting the tailcone and horizontal stabilizer for corrosion and cracks and repairing or replacing damaged parts as necessary. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective December 7, 2020.
Supplementary Information: The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Textron Aviation Inc. (Textron) (type certificate previously held by Cessna Aircraft Company) Models 180, 180A, 180B, 180C, 180D, 180E, 180F, 180G, 180H, 180J, 180K, 182, 182A, 182B, 182C, 182D, 185, 185A, 185B, 185C, 185D, 185E, A185E, and A185F airplanes. The NPRM published in the Federal Register on May 14, 2020 (85 FR 28890). The NPRM was prompted by a report of cracks found in the tailcone and horizontal stabilizer attachment structure on a Textron Model 185 airplane. The FAA discovered similar conditions on 29 additional Textron 180 and 185 series airplanes and determined that the combination of the attachment structure design and high loads during landing contribute to the development of cracks in the tailcone and horizontal stabilizer attachment structure. The NPRM proposed to require inspecting the tailcone and horizontal stabilizer for corrosion, cracks, and loose or sheared rivets and repairing or replacing damaged parts as necessary. The FAA is issuing this AD to prevent failure of the horizontal stabilizer to tailcone attachment, which could lead to tail separation with consequent loss of control of the airplane.
