(d) Subject Air Transport Association (ATA) of America Code 53, Fuselage. (e) Unsafe Condition This AD was prompted by Textron's report of a manufacturing defect which affects the durability of the aft canted bulkhead metallic structure. The manufacturing defect directly affects the bond integrity of the vertical and horizontal stiffeners on the aft canted bulkhead metallic structure. We are issuing this AD to prevent disbonding of the horizontal and vertical stiffeners on the aft canted bulkhead. Loss of bond integrity could result in a structural failure that may lead to separation of the cruciform tail and loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified,unless already done. (g) Repetitive Inspections Before the accumulation of 7,000 total flight hours, or within 100 flight hours after the effective date of this AD, whichever occurs later, perform a general visual inspection for disbonding and paint cracking around the edges of the stiffeners on the aft canted bulkhead, in accordance with the Accomplishment Instructions of Cessna Service Letter SL680-53-05, Revision 2, dated September 30, 2015. Repeat the general visual inspection thereafter at intervals not to exceed 100 flight hours, until the modification required by paragraph (i) of this AD is accomplished. (h) Repair If, during any inspection required by paragraph (g) of this AD, any disbonding or cracked paint is found, before further flight, obtain instructions approved by the Manager, Wichita Aircraft Certification Office (ACO), ACE-118W, FAA, and, within the compliance time specified in those instructions, accomplish the instructions accordingly. (i)Modification At the applicable compliance time specified in paragraph (i)(1) or (i)(2) of this AD, modify the airplane by installing additional stiffeners on the aft canted bulkhead, in accordance with the Accomplishment Instructions of Cessna Service Bulletin SB680-53-08, Revision 2, dated November 2, 2016, except as provided by paragraphs (k) and (l) of this AD. Doing this modification terminates the repetitive inspections required by paragraph (g) of this AD. (1) For airplanes that have accumulated 7,000 or more total flight hours as of the effective date of this AD: Within 1,800 flight hours or 24 months, whichever occurs first, after the effective date of this AD. (2) For airplanes that have accumulated less than 7,000 total flight hours as of the effective date of this AD: Within 3,600 flight hours or 48 months, whichever occurs first, after the effective date of this AD. (j) Credit for Previous Actions (1) This paragraph provides credit for actions required by paragraph (g) of this AD, if those actions were performed before the effective date of this AD using Cessna Service Letter SL680-53-05, dated December 22, 2014; or Cessna Service Letter SL680-53-05, Revision 1, dated March 12, 2015. (2) This paragraph provides credit for actions required by paragraph (i) of this AD, if those actions were performed before the effective date of this AD using Cessna Service Bulletin SB680-53-08, dated September 28, 2015. (k) Exceptions to Service Information Specifications Although Cessna Service Bulletin SB680-53-08, Revision 2, dated November 2, 2016, specifies using the latest revision of Drawing 6991119, this AD allows using any revision level of that drawing.

(m) Special Flight Permit Special flight permits, as described in Section 21.197 and Section 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199), are not allowed.
