Overview

This document is an Airworthiness Directive (AD) issued by Transport Canada, specifically addressing the Diamond DA62 aircraft. It outlines a critical issue regarding the horizontal stabilizer attachment bolts, which were initially specified with incorrect torque values in the Aircraft Maintenance Manual (AMM). The directive mandates corrective actions to ensure the safety and structural integrity of the aircraft. It is aimed at aircraft owners, maintenance personnel, and operators of the DA62, emphasizing the importance of compliance with the updated torque specifications to prevent potential loss of control due to stabilizer detachment.

  • The AD CF-2024-02 is effective from January 26, 2024.
  • It applies to DA62 aircraft serial numbers 62.C001 to 62.C044 and 62.008 to 62.203.
  • All 16 horizontal stabilizer attachment bolts must be torqued to the correct specifications within 30 days or 30 hours of air time.
  • The incorrect torque values could lead to structural failure and loss of control of the aircraft.
  • Compliance with Mandatory Service Bulletin 62-052 is required for corrective actions.

Applicability

The directive applies to Diamond DA62 aircraft with serial numbers ranging from 62.C001 to 62.C044 and 62.008 to 62.203.

Background

The AD highlights that the DA62 AMM initially listed standard torque values for the horizontal stabilizer attachment bolts, which were later found to be incorrect. The correct torque values are crucial for maintaining the structural integrity of the aircraft.

Corrective Actions

Operators must review the aircraft technical records and ensure that all 16 attachment bolts of the horizontal stabilizer are torqued to the correct specifications within 30 days or 30 hours of air time, whichever comes first. This must be done in accordance with the instructions provided in Mandatory Service Bulletin 62-052.

Safety notes

  • Using the incorrect torque value during installation of the horizontal stabilizer attachment bolts could result in loss of structural integrity and lead to the separation of the horizontal stabilizer.

TP 7245E 1 of 1 AD Number: CF-2024-02 A IR W O R T H IN E S S D IR E C T IV E This Airworthiness Directive (AD) is issued pursuant to Canadian Aviation Regulation (CAR) 521.427. No person shall conduct a take-off or permit a take-off to be conducted in an aircraft that is in their legal custody and control, unless the requirements of CAR 605.84 pertaining to ADs are met. Standard 625 - Aircraft Equipment and Maintenance Standards Appendix H provides information concerning alternative means of compliance (AMOC) with ADs. Number: CF-2024-02 ATA: 55 Effective Date: 26 January 2024 Type Certificate: A-273 Subject: Stabilizers – Horizontal Stabilizer – Incorrect Torque Specified for Attachment Bolts Applicability: Diamond Aircraft Industries Inc. model DA 62 aeroplanes, serial numbers 62.C001 through 62.C044 and 62.008 through 62.203. Compliance: As indicated below, unless already accomplished. Background: The DA 62 Aircraft Maintenance Manual (AMM) initially specified standard torque values for the horizontal stabilizer attachment bolts. The bolts were designed to require a higher torque value, and as such, the AMM was later updated to the correct special value. During the years when the AMM specified the incorrect torque value, there might have been occurrences where the removal of the horizontal stabilizer attachment bolts was required and the lower torque value was used for the installation of the bolts. The use of the lower torque value during installation could result in the loss of structural integrity and lead to the separation of the horizontal stabilizer and loss of control of the aeroplane. Corrective Actions: Within 30 days or 30 hours air time, whichever occurs later, review the aircraft technical records and torque all 16 attachment bolts of the horizontal stabilizer as required, in accordance with the Accomplishment Instructions of Mandatory Service Bulletin 62-052 Revision 0 dated 18 September 2023, or later revisions approved by the Chief, Continuing Airworthiness, Transport Canada. Authorization: For the Minister of Transport, ORIGINAL SIGNED BY Jenny Young Chief, Continuing Airworthiness Issued on 12 January 2024 Contact: Grant Walker, Continuing Airworthiness, Ottawa, telephone 888-663-3639, facsimile 613-996-9178 or e- mail TC.AirworthinessDirectives-Consignesdenavigabilite.TC@tc.gc.ca or any Transport Canada Centre.
