REASON This AOT is issued to inform operators about: - The risk of the slide upper latch not fully locked on the upper door mounting-bracket. - The necessary inspections and the corrective actions if the slide upper latch is not fully locked. 3.1 FACTS AND BACKGROUND Airbus informs operators that there was an occurrence of a slide with the decorative cover falling from the door mid-flight during turbulence. The slide pack came to lay on the ground, on top of the slide decorative cover. No inflation was initiated. ### Page 2 Airbus Amber ALERT OPERATORS TRANSMISSION - AOT AOT ref: A25P033-25 Rev 00 Page 2 of 20 Date: 18-JUN-2025 C80_AOT_FM1104649_v10.0 © AIRBUS S.A.S. 2025. ALL RIGHTS RESERVED. CONFIDENTIAL AND PROPRIETARY DOCUMENT 3.2 INVESTIGATION AND ROOT CAUSE With the upper latch correctly locked, it is physically impossible for a slide pack to drop from the door. Therefore, the slide upper latch is suspected of not being fully locked. Slide upper latches were inspected on aircraft in production. Two slide upper latches were found not correctly locked. Lock indicator design was changed, introducing 3 different iterations of the upper latch. The root cause of these events was the design iterations of the lock indication were not reflected in the updated installation documentation. Thus, creating a potential misinterpretation. An update of the production documentation and inspections have been done to cover the correct slide installation in production on aircrafts delivered after the 7th November 2024. The MP task reference 1 is under review to avoid further misinterpretation during maintenance on in service aircrafts. Figure 1: Design iterations of upper latch lock indication 3.3 CONSEQUENCES If the slide is not correctly installed and locked, there is a risk that the slide will fall down on the aircraft floor and: - cause injury to persons - become unserviceable. ### Page 3 Airbus Amber ALERT OPERATORS TRANSMISSION - AOT AOT ref: A25P033-25 Rev 00 Page 3 of 20 Date: 18-JUN-2025 C80_AOT_FM1104649_v10.0 © AIRBUS S.A.S. 2025.

OBJECTIVES OF THIS AOT For Configuration 1 This AOT requires: - The inspection of all slide upper latches. - The correct locking of the slide upper latch with the upper door mounting-bracket on all slides. For Configuration 2 This AOT requires: - The inspection of the slide upper latches on which maintenance has been performed. - The correct locking of the slide upper latch with the upper door mounting-bracket on slides on which maintenance has been performed. A flowchart is available in the annex to clarify the actions of this AOT (Figure 12). 5. MAINTENANCE PROCEDURE NOTE: The accomplishment instructions of this AOT include procedures given in other documents or in other sections of the AOT. When the words “refer to” are used and the operator has a procedure or tool accepted by the local authority he belongs to, the accepted alternative procedure or tool can be used. When the words “in accordance with” are used then the given procedure must be followed. NOTE: The access and close-up instructions, not comprising return to service tests, in this AOT do not constitute or affect the technical intent of the AOT. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the AOT is met within the set parameters. NOTE: This AOT is classified mandatory or expected to be classified mandatory by an Airworthiness Directive (AD). The paragraphs 5.1 ACCOMPLISHMENT TIMESCALE, 5.4 INSPECTION and 5.5 INSTRUCTIONS are Required for Compliance (RC) and must be done to comply with the AD. To allow more flexibility, the rule "refer to" and "in accordance with" will apply to these paragraphs 5.1, 5.4 and 5.5. Other paragraphs are recommended and may be deviated from, done as part of other actions or done with accepted methods different from those given in the AOT, as long as the RC paragraphs can be done and the aircraft can be put back into a serviceable condition. 5.1 ACCOMPLISHMENT TIMESCALE - (RC) NOTE: Accomplishment timescale can be superseded by AD compliance time if any. You must do the inspection of the concern slide upper latches before 31 October 2025. 5.2 MANPOWER The time necessary to do the inspection of the slide upper latches is 0.2 Man Hours per door, Representing about 1.5 hours if all 8 slides of the aircraft have to be inspected. NOTE: Work in parallel could be done, reducing the required elapsed time for the replacement. ### Page 4 Airbus Amber ALERT OPERATORS TRANSMISSION - AOT AOT ref: A25P033-25 Rev 00 Page 4 of 20 Date: 18-JUN-2025 C80_AOT_FM1104649_v10.0 © AIRBUS S.A.S. 2025.
