ANNEX II — OCCURRENCES RELATED TO TECHNICAL CONDITIONS, MAINTENANCE AND REPAIR OF THE AIRCRAFT

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, or appliance covered by the type-certificate, restricted type-certificate, supplemental type-certificate, ETSO authorisation, major repair design approval or any other relevant approval deemed to have been issued under Commission Regulation (EU) No 748/2012 ().

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.

(7)Incorrect assembly or installation of components of the aircraft found during an inspection or test procedure not intended for that specific purpose.

(8)Wrong assessment of a serious defect, or serious non-compliance with MEL and Technical logbook procedures.

(9)Serious damage to Electrical Wiring Interconnection System (EWIS).

(10)Any defect in a life-controlled critical part causing retirement before completion of its full life.

(11)The use of products, components or materials, from unknown, suspect origin, or unserviceable critical components.

(12)Misleading, incorrect or insufficient applicable maintenance data or procedures that could lead to significant maintenance errors, including language issue.

(13)Incorrect control or application of aircraft maintenance limitations or scheduled maintenance.

(14)Releasing an aircraft to service from maintenance in case of any non-compliance which endangers the flight safety.

(15)Serious damage caused to an aircraft during maintenance activities due to incorrect maintenance or use of inappropriate or unserviceable ground support equipment that requires additional maintenance actions.

(16)Identified burning, melting, smoke, arcing, overheating or fire occurrences.

(17)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.

(18)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.
