1. The authority citation for part 39 continues to read as follows: Authority: 9 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2022-25-01 The Boeing Company: Amendment 39-22257; Docket No. FAA-2022-1051; Project Identifier AD-2022-00089-T. (a) Effective Date This airworthiness directive (AD) is effective February 16, 2023. (b) Affected ADs None. (c) Applicability This AD applies to The Boeing Company airplanes specified in paragraphs (c)(1) through (3) of this AD, certificated in any category. (1) Model 707-100 Long Body, -200, -100B Long Body, and -100B Short Body series airplanes. (2) Model 707-300, -300B, -300C, and -400 series airplanes. (3) Model 727, 727C, 727-100, 727-100C, 727-200, and 727-200F series airplanes. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a report indicating cracking in fastener holes at the center wing box and at certain positions of the rear spar and lower skin on a Model 737-300 airplane. A cross model review determined that similar cracking of the fastener holes in the center wing box lower skin could occur on Model 707 and Model 727 airplanes. The FAA is issuing this AD to address cracking in the center wing box lower skin or rear spar lower chord, which could result in the inability of the structure to sustain limit load and adversely affect the structural integrity of the airplane.
