1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-05-03 The Boeing Company: Amendment 39-23276; Docket No. FAA-2025-1719; Project Identifier AD-2024-00382-T. (a) Effective Date This airworthiness directive (AD) is effective April 16, 2026. (b) Affected ADs This AD affects AD 2010-06-16, Amendment 39-16241 (75 FR 12670, March 17, 2010) (AD 2010-06-16). (c) Applicability (1) This AD applies to The Boeing Company Model 767-200 and 767-300 series airplanes, certificated in any category, listed in paragraphs (c)(1)(i) through (iii) of this AD. (i) Airplanes identified as Group 13 and 14 in Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024. (ii) Model 767-200 series airplanes converted to a special freighter by Supplemental Type Certificate (STC) ST01433SE. (iii) Model 767-300 series airplanes converted to a special freighter by STC ST02040SE. (2) Installation of STC ST01920SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01920SE is installed, a "change in product" alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17. (d) Subject Air Transport Association (ATA) of America Code 53, Fuselage. (e) Unsafe Condition This AD was prompted by reports of scribe lines found at skin lap joints and butt joints, around external repairs and antennas, and at locations where external decals had been cut. The FAA is issuing this AD to address scribe lines, which could develop into fatigue cracks in the skin and cause rapid decompression of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions: Group 13 and 14 Airplanes For airplanes identified in paragraph (c)(1)(i) of this AD: Except as specified in paragraphs (i)(1) and (2) of this AD, at the applicable times specified in tables 1.1 and 1.2 under the "Compliance" paragraph of Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024, do the actions specified in, and in accordance with, the "Action" column and footnotes of tables 1.1 and 1.2 under the "Compliance" paragraph of Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024. (h) Required Actions: STC-Modified Airplanes For airplanes identified in paragraphs (c)(1)(ii) and (iii) of this AD: Except as specified in paragraphs (i)(2) through (5) of this AD, at the applicable times specified in the Accomplishment Instructions of IAI-Aviation Group Service Bulletin 368-53-073, Revision 2, dated September 2025, do detailed inspections for scribe lines of skin lap joints around external repairs and antennas and at locations where external decals might have been cut, and do all applicable related investigative and corrective actions, by accomplishing all applicable actions specified in the Accomplishment Instructions of Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024. The inspection exemptions noted in paragraph 2., "Accomplishment Instructions" of IAI-Aviation Group Service Bulletin 368-53-073, Revision 2, dated September, apply to actions required by this paragraph. (i) Exceptions to Service Bulletin Specifications (1) Where the Compliance Time columns in tables 1.1 and 1.2 under the "Compliance" paragraph of Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024, refer to the "revision 03 issue date of this service bulletin," this AD requires using the effective date of this AD. (2) Where Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024, specifies contacting Boeing for repair instructions, this AD requires doing the repair using a method approved in accordance with the procedures in paragraph (l) of this AD. (3) Where paragraph 1) of the Accomplishment Instructions of IAI-Aviation Group Service Bulletin 368-53-073, Revision 2, dated September 2025, refers to applying applicable factors to "the initial inspection threshold," for this AD, apply the applicable factors to the applicable initial compliance times specified in the "Compliance" paragraph of Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024. Where the Compliance Time columns in the tables under the "Compliance" paragraph of Boeing Alert Service Bulletin 767-53A0193, Revision 3, dated June 27, 2024, refer to the "the original issue date on this service bulletin," this AD requires using the effective date of this AD. Note 1 to paragraph (i)(3): For Model 767-200 airplanes, the new compliance times are 60% of the original initial compliance time. For example, an initial compliance time of 25,000 total flight cycles is reduced to 15,000 total flight cycles ( i.e., 25,000 × 0.60 = 15,000). Note 2 to paragraph (i)(3): For Model 767-300 airplanes, the new compliance times are 46% of the original initial compliance time. For example, an initial compliance time of 25,000 total flight cycles is reduced to 11,500 total flight cycles ( i.e., 25,000 × 0.46 = 11,500). (4) Where IAI-Aviation Group Service Bulletin 368-53-073, Revision 2, dated September 2025, specifies contacting IAI for inspections or repair instructions, this AD requires doing the inspections and repairs using a method approved in accordance with the procedures in paragraph (l) of this AD.
