145.B.350   Findings and corrective actions; observations

• (a) The competent authority shall have a system in place to analyse findings for their safety significance.

• (b) A level 1 finding shall be issued by the competent authority when any significant non-compliance is detected with the applicable requirements of Regulation (EU) 2018/1139 and its delegated and implementing acts, with the organisation’s procedures and manuals, or with the organisation’s certificate including the terms of approval, which lowers safety or seriously endangers flight safety. Level 1 findings shall also include:
• (1) any failure to grant the competent authority access to the organisation’s facilities referred to in point 145.A.140 during normal operating hours and after two written requests;
• (2) obtaining the organisation certificate or maintaining its validity by falsification of the submitted documentary evidence;
• (3) any evidence of malpractice or fraudulent use of the organisation certificate;
• (4) the lack of an accountable manager.

• (c) A level 2 finding shall be issued by the competent authority when any non-compliance is detected with the applicable requirements of Regulation (EU) 2018/1139 and its delegated and implementing acts, with the organisation’s procedures and manuals, or with the organisation’s certificate including the terms of approval, which is not classified as a level 1 finding.

• (d) When a finding is detected during oversight or by any other means, the competent authority shall, without prejudice to any additional action required by Regulation (EU) 2018/1139 and its delegated and implementing acts, communicate in writing the finding to the organisation and request corrective action to address the non-compliance identified. If a level 1 finding directly relates to an aircraft, the competent authority shall inform the competent authority of the Member State in which the aircraft is registered.
• (1) If there are any level 1 findings, the competent authority shall take immediate and appropriate action to prohibit or limit the activities of the organisation involved and, if appropriate, it shall take action to revoke the certificate or to limit or suspend it in whole or in part, depending on the extent of the level 1 finding, until successful corrective action has been taken by the organisation.
• (2) If there are any level 2 findings, the competent authority shall:
• (i) grant the organisation a corrective action implementation period that is appropriate to the nature of the finding, and that in any case shall initially not be more than 3 months. The period shall commence from the date of the written communication of the finding to the organisation requesting corrective action to address the non-compliance identified. At the end of that period, and subject to the nature of the finding, the competent authority may extend the 3-month period provided that a corrective action plan has been agreed with the competent authority;
• (ii) assess the corrective action plan and implementation plan proposed by the organisation, and if the assessment concludes that they are sufficient to address the non-compliance, accept them.
• (3) If the organisation fails to submit an acceptable corrective action plan, or fails to perform the corrective action within the time period accepted or extended by the competent authority, the finding shall be raised to level 1 and action shall be taken as laid down in point (d)(1).
• (4) The competent authority shall record all the findings that it has raised or that have been communicated to it in accordance with point (e) and, where applicable, the enforcement measures it has applied, as well as all corrective actions and the dates of the action closures for all the findings.

• (e) Without prejudice to any additional enforcement measures, when an authority performing the oversight tasks pursuant to point 145.B.300(d) identifies any non-compliance with the applicable requirements of Regulation (EU) 2018/1139 and its delegated and implementing acts by an organisation certified by the competent authority of another Member State or the Agency, it shall inform that competent authority and provide an indication of the level of the finding.

• (f) The competent authority may issue observations for any of the following cases not requiring level 1 or level 2 findings:
• (1) for any item whose performance has been assessed to be ineffective;
• (2) when it has been identified that an item has the potential to cause a non-compliance under points (b) or (c);
• (3) when suggestions or improvements are of interest for the overall safety performance of the organisation.

The observations issued under this point shall be communicated in writing to the organisation and recorded by the competent authority.

145.B.355   Suspension, limitation and revocation

The competent authority shall:

• (a) suspend a certificate when it considers that there are reasonable grounds that such action is necessary to prevent a credible threat to aircraft safety;

• (b) suspend, revoke or limit a certificate if such action is required pursuant to point 145.B.350;

• (c) suspend or limit in whole or in part a certificate if unforeseeable circumstances outside the control of the competent authority prevent its inspectors from discharging their oversight responsibilities over the oversight planning cycle.

Appendix I

Authorised Release Certificate — EASA Form 1

The provisions of Appendix II to Annex I (Part-M) apply.

Appendix II

Class and rating system for the terms of approval of Part-145 maintenance organisations

• (a) Except as stated otherwise for the smallest organisations referred to in point (m), the table referred to in point (l) provides the possible classes and ratings to be used to establish the terms of approval of the certificate of the organisation approved in accordance with Annex II (Part-145). An organisation must be granted terms of approval that range from a single class and rating with limitations to all classes and ratings with limitations.

• (b) In addition to the table in point (l), each maintenance organisation is required to indicate its scope of work in its MOE.

• (c) Within the approval class(es) and rating(s) established by the competent authority, the scope of work specified in the MOE defines the exact limits of its approval. It is therefore essential that the approval class(es) and rating(s) and the organisation’s scope of work match.

• (d) A category A class rating means that the maintenance organisation may carry out maintenance on aircraft and components (including engines and/or auxiliary power units (APUs)), in accordance with the aircraft maintenance data or, if agreed by the competent authority, in accordance with the component maintenance data, only while such components are fitted to the aircraft. Nevertheless, such an A-rated maintenance organisation may temporarily remove a component for maintenance in order to improve access to that component, except when its removal generates the need for additional maintenance that the organisation is not approved to perform. Such removal of component for maintenance by A-rated maintenance organisation shall be subject to an appropriate control procedure in the MOE. The limitation column must specify the scope of such maintenance, thereby indicating the extent of the approval.

• (e) Category A class ratings are subdivided into ‘Base’ or ‘Line’ maintenance categories. Such an organisation may be approved for either ‘Base’ or ‘Line’ maintenance, or both. It should be noted that a ‘Line’ facility located at a main base facility requires a ‘Line’ maintenance approval.

• (f) A category B class rating means that the maintenance organisation may carry out maintenance on uninstalled engines and/or APUs and engine and/or APU components, in accordance with the engine and/or APU maintenance data or, if agreed by the competent authority, in accordance with the component maintenance data, only while such components are fitted to the engine and/or the APU. Nevertheless, such a B-rated approved maintenance organisation may temporarily remove a component for maintenance in order to improve access to that component, except when its removal generates the need for additional maintenance that the organisation is not approved to perform. The limitation column must specify the scope of such maintenance, thereby indicating the extent of the approval. A maintenance organisation that is approved with a category B class rating may also carry out maintenance on an installed engine during aircraft base and line maintenance, provided that an appropriate control procedure in the MOE has been approved by the competent authority. The scope of work in the MOE shall reflect those activities if they are permitted by the competent authority.

• (g) A category C class rating means that the maintenance organisation may carry out maintenance on uninstalled components (excluding complete engines and APUs) that are intended to be fitted on the aircraft or the engine/APU. The limitation column must specify the scope of such maintenance, thereby indicating the extent of the approval. A maintenance organisation that is approved with a category C class rating may also carry out maintenance on an installed component (other than a complete engine/APU) during aircraft base and line maintenance, or at an engine/APU maintenance facility provided that an appropriate control procedure in the MOE has been approved by the competent authority. The scope of work in the MOE shall reflect those activities if they are permitted by the competent authority.

• (h) A category D class rating is a self-contained class rating that is not necessarily related to a specific aircraft, engine or other component. The D1 – Non-Destructive Testing (NDT) rating is only necessary for a maintenance organisation that carries out NDT as a particular task for another organisation. A maintenance organisation that is approved with a class rating in the A, B or C category may carry out NDT on products that it maintains without the need for a D1 class rating provided that the MOE contains appropriate NDT procedures.

• (i) The limitation column is intended to give competent authorities the flexibility to customise an approval for any particular organisation. Ratings may only be mentioned on the approval if they are appropriately limited. The table in point (l) specifies the types of limitations that are possible. It is acceptable to stress in the limitation column the maintenance task rather than the type or manufacturer of the aircraft or engine, if that is more appropriate to the organisation (an example could be avionics systems installations and the related maintenance). If that is mentioned in the limitation column, it indicates that the maintenance organisation is approved to carry out maintenance up to and including that particular type/task.

• (j) When reference is made to the series, type and group in the limitation column of class A and B, it shall be understood as follows:
• — ‘series’ means a specific type series such as the Airbus 300, 310 or 319, or the Boeing 737-300 series, the RB211-524 series, the Cessna 150 or Cessna 172, the Beech 55 series, the continental O-200 series, etc.,
• — ‘type’ means a specific type or model such as the Airbus 310-240 type, the RB 211-524 B4 type, or the Cessna 172RG type. Any number of series or types may be quoted,
• — ‘group’ means, for example, Cessna single piston engine aircraft or Lycoming non-supercharged piston engines, etc.

• (k) By way of derogation from point 145.A.85(a)(1), when a component capability list is used that could be subject to frequent amendments, then the organisation may propose to include such amendments in the procedure referred to in point 145.A.85(c) for changes not requiring prior approval.

• (l) Table CLASS RATING LIMITATION BASE LINE AIRCRAFT A1 Aeroplanes above 5 700 kg maximum take-off mass (MTOM) [Shall state the aeroplane manufacturer or the group or series or type and/or the maintenance tasks] Example: Airbus A320 Series [YES/NO] [^E0014] [YES/NO] [^E0014] A2 Aeroplanes of 5 700 kg MTOM and below [Shall state the aeroplane manufacturer or the group or series or type and/or the maintenance tasks] Example: DHC-6 Twin Otter Series State whether the issuing of airworthiness review certificates is authorised (only possible for aircraft covered by Annex Vb (Part-ML)) [YES/NO] [^E0014] [YES/NO] [^E0014] A3 Helicopters [Shall state the helicopter manufacturer or the group or series or type and/or the maintenance task(s)] Example: Robinson R44 State whether the issuing of airworthiness review certificates is authorised (only possible for aircraft covered by Annex Vb (Part-ML)) [YES/NO] [^E0014] [YES/NO] [^E0014] A4 Aircraft other than A1, A2 and A3 aircraft [Shall state the aircraft category (sailplane, balloon, airship, etc.) when applicable, the manufacturer or group or series or type and/or the maintenance task(s)] State whether the issuing of airworthiness review certificates is authorised (only possible for aircraft covered by Annex Vb (Part-ML)) [YES/NO] [^E0014] [YES/NO] [^E0014] ENGINES B1 Turbine [Shall state the engine series or type and/or the maintenance task(s)] Example: PT6A Series B2 Piston [Shall state the engine manufacturer or group or series or type and/or the maintenance task(s)] B3 APU [Shall state the engine manufacturer or series or type and/or the maintenance task(s)] B4 Engines other than B1, B2 and B3 [Shall state the engine manufacturer or group or series or type and/or the maintenance task(s)] COMPONENTS OTHER THAN COMPLETE ENGINES OR APUs C1 Air Cond & Press [Shall state the aircraft type or aircraft manufacturer or component manufacturer or the particular component and/or cross-refer to a capability list in the exposition and/or the maintenance task(s)] Example: PT6A Fuel Control C2 Auto Flight C3 Comms and Nav C4 Doors – Hatches C5 Electrical Power & Lights C6 Equipment C7 Engine – APU C8 Flight Controls C9 Fuel C10 Rotorcraft – Rotors C11 Rotorcraft – Trans C12 Hydraulic Power C13 Indicating – recording system C14 Landing Gear C15 Oxygen C16 Propellers C17 Pneumatic & Vacuum C18 Protection ice/rain/fire C19 Windows C20 Structural C21 Water ballast C22 Propulsion Augmentation C23 Other SPECIALISED SERVICES D1 Non-Destructive Testing [Shall state particular NDT method(s)] (¹) – Delete as appropriate

• (m) A maintenance organisation which employs only one person to both plan and carry out all its maintenance activities can only hold limited terms of approval. The maximum permissible limits are as follows: CLASS RATING LIMITATION AIRCRAFT A2 AEROPLANES of 5 700 KG MTOM OR LESS WITH PISTON ENGINE or ELECTRIC POWER PLANT WITH NO FUEL CELL AIRCRAFT A3 HELICOPTERS of 3 175 KG MTOM OR LESS WITH SINGLE-PISTON ENGINE or ELECTRIC POWER PLANT WITH NO FUEL CELL AIRCRAFT A4 SAILPLANES, BALLOONS, AIRSHIPS AND ANY AIRCRAFT of 3 175 KG MTOM OR LESS WITH SINGLE-PISTON ENGINE or ELECTRIC POWER PLANT WITH NO FUEL CELL ENGINES B2 LESS THAN 450 HP ENGINES B4 ELECTRIC ENGINE COMPONENTS OTHER THAN COMPLETE ENGINES OR APUs C1 TO C23 AS PER CAPABILITY LIST SPECIALISED SERVICES D1 NDT NDT METHOD(S) TO BE SPECIFIED

It should be noted that such an organisation may be further limited by the competent authority in the terms of approval depending on the capabilities of the particular organisation.
