ANNEX II ‘ ANNEX II OCCURRENCES RELATED TO TECHNICAL CONDITIONS, MAINTENANCE AND REPAIR OF THE AIRCRAFT Remark : The occurrences listed in this Annex are also relevant for UAS for which a certificate or declaration for the design is required pursuant to Article 56(1) and (5) of Regulation (EU) 2018/1139. 1. MANUFACTURING Products, parts or appliances released from the production organisation with deviations from applicable design data that could lead to a potential unsafe condition as identified with the holder of the type-certificate or design approval. 2. DESIGN Any failure, malfunction, defect or other occurrence related to a product, part, or appliance which has resulted in or may result in an unsafe condition. Remark : This list is applicable to occurrences occurring on a product, part, appliance or the Control and Monitoring Unit (CMU) ( 1 ) , covered by the type-certificate, restricted type-certificate, supplemental type-certificate, ETSO authorisation, major repair design approval or any other relevant approval or declaration deemed to have been issued under Commission Regulation (EU) No 748/2012 ( 2 ) . 3. MAINTENANCE AND CONTINUING AIRWORTHINESS MANAGEMENT (1) Serious structural damage (for example: cracks, permanent deformation, delamination, debonding, burning, excessive wear, or corrosion) found during maintenance of the aircraft or component. (2) Serious leakage or contamination of fluids (for example: hydraulic, fuel, oil, gas or other fluids). (3) Failure or malfunction of any part of an engine or powerplant and/or transmission resulting in any one or more of the following: (a) non-containment of components/debris; (b) failure of the engine mount structure. (4) Damage, failure or defect of propeller, which could lead to in-flight separation of the propeller or any major portion of the propeller and/or malfunctions of the propeller control. (5) Damage, failure or defect of main rotor gearbox/attachment, which could lead to in-flight separation of the rotor assembly and/or malfunctions of the rotor control. (6) Significant malfunction of a safety critical system or equipment including emergency system or equipment during maintenance testing or failure to activate these systems after maintenance, including the CMU. (7) Abnormal behaviour of a system due to an information security incident (example: compromised information or data, malware infection, Distributed-Denial-of-Service (DDoS)). (8) Incorrect assembly or installation of components of the aircraft or the CMU, found during an inspection or test procedure not intended for that specific purpose. (9) Wrong assessment of a serious defect, or serious non-compliance with Minimum Equipment List (MEL) and Technical Logbook procedures. (10) Serious damage to Electrical Wiring Interconnection System (EWIS). (11) Any defect in a life-controlled critical part causing retirement before completion of its full life. (12) The use of products, non-installed equipment, components or materials, from unknown, suspect origin, or unserviceable critical components. (13) Misleading, incorrect or insufficient applicable maintenance data or procedures that could lead to significant maintenance errors, including language issue. (14) Incorrect control or application of the aircraft maintenance limitations, procedures or scheduled maintenance, including that of the CMU. (15) Releasing to service from maintenance an aircraft or the CMU in case of any non-compliance which endangers the flight safety. (16) Serious damage caused to an aircraft, to a part, or to the CMU during maintenance activities due to incorrect maintenance or use of inappropriate or unserviceable ground support equipment that requires additional maintenance actions. (17) Identified burning, melting, smoke, arcing, overheating or fire occurrences. (18) Any occurrence where the human performance, including fatigue of personnel, has directly contributed to or could have contributed to an accident or a serious incident. (19) Significant malfunction, reliability issue, or recurrent recording quality issue affecting a flight recorder system (such as a flight data recorder system, a data link recording system or a cockpit voice recorder system) or lack of information needed to ensure the serviceability of a flight recorder system, including those installed in the CMU. (20) Use or potential use of an unapproved configuration or installation of the CMU. ’ ( 1 ) In accordance with Article 3, point (38) of Delegated Regulation (EU) 2019/945, “control and monitoring unit (‘CMU’) means the equipment to control and monitor unmanned aircraft remotely, as defined in Article 3, point (32) of Regulation (EU) 2018/1139”. ( 2 ) Commission Regulation (EU) No 748/2012 of 3 August 2012 laying down implementing rules for the airworthiness and environmental certification of aircraft and related products, parts and appliances, as well as for the certification of design and production organisations ( OJ L 224, 21.8.2012, p. 1 , ELI: http://data.europa.eu/eli/reg/2012/748/oj ).
