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: 2024-07-03 Diamond Aircraft Industries Inc.: Amendment 39-22724; Docket No. FAA-2024-0991; Project Identifier MCAI-2024-00051-A. (a) Effective Date This airworthiness directive (AD) is effective April 24, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Diamond Aircraft Industries Inc. Model DA 62 airplanes, serial numbers 62.C001 through 62.C044 inclusive and 62.008 through 62.203 inclusive, certificated in any category. (d) Subject Joint Aircraft System Component (JASC) Code 5510, Horizontal Stabilizer Structure. (e) Unsafe Condition This AD was prompted by a report that certain revisions of the airplane maintenance manual specified incorrect torque values for the horizontal stabilizer attachment bolts. The FAA is issuing this AD to address incorrect torque values for the horizontal stabilizer attachment bolts. The unsafe condition, if not addressed, could result in premature wearing of the horizontal stabilizer attachment bolts, loss of structural integrity of the horizontal stabilizer, subsequent separation of the horizontal stabilizer from the fuselage, and loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Within 30 days or 30 hours time-in-service after the effective date of this AD, whichever occurs later, review the airplane maintenance records to determine if the horizontal stabilizer attachment bolts were last torqued to 45 newton meter (Nm) and if the torque value is not 45 Nm, or if the value cannot be determined, before further flight, torque the bolts to 45 Nm, in accordance with steps 3 through 6 of the Instructions, Section III, in Diamond Aircraft Industries Work Instruction WI-MSB-62-052, Revision 0, dated September 18, 2023, attached to Diamond Aircraft Industries Mandatory Service Bulletin MSB 62-052, Revision 0, dated September 18, 2023 (issued as one document).
