The classification is performed by the Office of Airworthiness together with the involved CVEs in accordance with Part 21.A.91, and documented in form AMN-DO-F01A. The Office of Airworthiness has to be aware of the interaction between disciplines and consequences this will have when assessing the effects of a change (i.e., operations and structures, systems and structures, systems and systems, etc.). The classification is approved by the Head of Office of Airworthiness. In any case of doubt the Office of Airworthiness asks the CAA IRI for further clarification. The Ameen Design Organization is allowed to approve the minor changes only. In the event of a design change being classified as Major, Ameen will apply for a Supplemental Type Certificate (STC) to be issued by the CAA IRI. (see subpart 3.8.2). Meanwhile, the Ameen Design Organization will contact an appropriate DOA holder with related scope of work (e.g. its design supplier(s)), in order to act as Ameen’s consultant in Major change certification process. For classification of changes in the following texts the wording “appreciable” is used. Following provides guidance on the word “appreciable” means as applied to the areas identified at airplane level. A. Weight- Appreciable changes are: a. Changes increasing the certified maximum or decreasing the certified minimum weight limits: - Max Taxi Weight - Max Take-off Weight - Max Zero Fuel Weight - Max Landing Weight - Minimum Flying Weight

53. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.3 Classification of Changes to the Type Certificate Page: 53 b. Changes in distribution of weight and the associated moment of inertia that would affect the spin characteristics, dynamic stability or flutter characteristics of the airplane B. Balance- Appreciable changes are: a. Changes in the certified center of gravity limits: - Decreasing the forward limit (i.e. move it more forward of the certificated forward limit) - Increasing the aft limit (i.e. move it further aft of the certificated aft limit) C. Structural Strength- Appreciable changes are: a. Changes to primary structure (structure that carries flight, ground, or pressure loads as defined in FAA AC 25.571-1, Damage Tolerance and Fatigue Evaluation of Structure), that is not obviously to the conservative side b. Changes in loads / load paths - Changes in material - Changes to method of construction - Changes to stiffness c. Increase of structural design speeds: - VA - VFE - VNE - VD d. Internal cabin changes: - Changes that increase floor loading limits - Changes to increase cargo compartment loading limits - Changes to cabin configuration resulting in relocation of major items (galleys, lavatories, etc.) e. Other factors: - Change of fatigue mission profile - New required structural inspections

54. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.3 Classification of Changes to the Type Certificate Page: 54 - Increase of control surface deflections - Changes that affect the flutter characteristics D. Reliability- Appreciable changes are: a. Changes that negatively (e.g. is it in curriculum) impact the airplane level reliability with the propensity for pilot distraction or preoccupation to the extent that a reduction in safety margins or rise in the level of preoccupation of the pilot’s attention (pilot workload) is likely to happen. E. Operational Characteristics- Appreciable changes are: a. Airplane, engine, and propeller changes that affect the performance data presented in their Pilot Operating Handbooks (POH) (including the approval of different take-off and landing surface conditions) b. Engine cooling changes c. Change in types of acceptable fuel d. Engine and / or propeller changes e. Changes to emergency procedures in the POH f. Changes to operating limits in the POH, including changes to the ambient envelope (altitudes and temperatures) g. Changes that affect the flight characteristics of the airplane in a manner that is perceptible to the pilot (e.g. change in control surface deflection and/or gearing; thrust/power changes; external configuration changes) h. System changes that increase pilot workload i. Changes in the certified maximum seating capacity j. Changes to unusable fuel supply F. Environmental protection such as noise, fuel venting or exhaust emission, a. Changes that increase the noise level b. Changes that reduce noise level, when the reduction shall be identified on the POH c. Changes in the emissions level

55. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.3 Classification of Changes to the Type Certificate Page: 55 G. Other characteristics affecting the airworthiness of the product- Appreciable changes are: a. Changes as a result of a safety issue b. Changes to the Airworthiness Limitations Manual c. Interior changes that affect passenger safety (for example new items of mass in the interior, installation of air bag seat belts, changes that affect occupant injury characteristics compliance (e.g. Head Injury Criteria (HIC)), new seats, etc.) d. Changes to systems or equipment that have an effect on safety or are perceptible to the pilot. 3.3.1 Minor Changes Based on the above mentioned explanation of the “appreciable” meaning, a change can be classified minor, if it has no appreciable effect on Weight, Balance, Structural strength, Reliability, Operational characteristics, Fuel venting, Exhaust Emissions or Noise, and any other characteristics affecting the airworthiness of the product. 3.3.2 Major Changes A change is judged to have an appreciable effect on other characteristics affecting the airworthiness of the product and therefore should be classified major, in particular but not only, when one or more of the following conditions are met:  The change requires an adjustment of the type‐certification basis (such as special conditions, equivalent safety findings, elect to comply, earlier certification specification, reversion, later certification specification).  The Design Organization proposes a new interpretation of the certification specification used for the type‐certification basis that has not been published as AMC material or otherwise agreed with the CAA IRI.  The demonstration of compliance uses methods that have not been previously accepted as appropriate for the nature of the change, or for similar changes to other products designed by the Design Organization.

56. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.3 Classification of Changes to the Type Certificate Page: 56  The extent of the new substantiation data necessary to comply with the applicable certification specifications and the degree to which the original substantiation data has to be reassessed and re‐evaluated is considerable.  The change alters the Airworthiness Limitations or the Operating Limitations.  The change is made mandatory by an Airworthiness Directive (AD) or the change is the terminating action of an AD. (A design change previously classified minor and approved prior to the AD issuance decision needs no re‐classification. However, the CAA IRI retains the right to review the change and re‐classify/ re‐approve if found necessary)  The change introduces or affects functions where the failure effect is classified as catastrophic or hazardous.  The change is being accomplished using non‐standard or non‐acceptable methods, techniques, or elementary operations.  The change causes an increase in failure rate and thus raising the risk of failure.  The consequences of failure will be more significant.  The intended change amends the failure criteria for the product.  The change affect primary structure or life limited components.  The change is intended to demonstrate a first‐time installation of a system that will establish new airworthiness criteria or set new precedents.  The change has appreciable (i.e. classified as Major) effects on any Operational Suitability Data (OSD) constituents (MMEL, FCD, CCD, SIMD).  Any other appreciable effect on airworthiness? Other appreciable effects can be items such as  emergency evacuation, crew/passenger safety, placards/signs etc. 3.3.3 Notes 1) On some occasions, the classification process will be initiated at a time when some of the data necessary to make a classification decision is not yet available. In this situation, the final decision should wait for the availability of that data.

57. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.3 Classification of Changes to the Type Certificate Page: 57 2) The classification form is prepared by a Design Engineer and approved by Compliance Verification Engineer(s) of all affected field(s), as well as Head of Office of Airworthiness. 3) The Office of Airworthiness will monitor, on a regular basis, the justifications for a classification decision to ensure the criteria of Part 21.A.91, 21.A.435 and GM 21.A.91, GM 21.A.435 is being applied across all disciplines of the Design Organization. 4) Whenever there is doubt as to the classification of a change or repair, the Agency should be consulted for clarification, by the Head of Office of Airworthiness. 5) When the strict application criteria result in a Major classification, the Head of Office of Airworthiness may request re-classification, if justified, and CAA IRI could take the responsibility in re-classifying the change. 6) Skills and experience accumulated by the Design Organization on similar changes or repairs, together with the extent and complexity of the compliance demonstration to be developed, can be used in determining the approval route. 7) Those involved with classification should always be aware of the interaction between disciplines and the consequences this will have when assessing the effects of a change. 8) All relevant certification specifications are to be considered for the change by reference to the applicable certification specifications. If no specific certification specifications are applicable to the change or repair, the review should be carried out at the level of the part of the system where the change or repair is integrated and where specific certification specifications are applicable. 9) Reasons for a classification decision shall be recorded by the Office of Airworthiness, using the form AMN-DO-F01A. 10) Minor changes to that part of a product covered by a STC shall be classified and approved in accordance with CAA IRI Part 21 Subpart D. 11) Each major change to that part of a product covered by a STC shall be approved as a separate STC in accordance with CAA IRI Part 21 Subpart E. If a major change to that part of a product

60. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.4 TC Basis for a Change to Type Certification Page: 60 3.4 TC Basis for a Change to Type Certification The Type Certification (TC) basis is to identify what certification specifications will be used in the demonstration of compliance. The type certification basis must consider if the change is substantial or significant. Also, it must consider whether it is practical, or it will contribute materially to the safety of the product to include the latest requirements or not. The Head of Office of Airworthiness (HOA) is responsible to define the type certification basis according to Part 21.A.101 and GM to 21.A.101, and he/she will decide which certification basis will be used depending on practicability, safety and quality benefits. The type certification basis decides whether the latest certification specifications will be used or if earlier specifications suffice (not earlier than the existing type-certification basis). See the flowchart in figure 5 below. Refer to GM to 21.A.101 for more details. The certification basis for aircraft and OSD has been defined in the TCDS. For each change, the type certification basis is recorded in the Certification Program (CP).

Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.5 Certification Program (CP) Page: 62 3.5 Certification Program (CP) In order to guarantee a coordinated and efficient course of type change investigation; the HOA (supported by the CAA IRI, for major change only) shall develop together with the relevant CVEs the Certification Program (CP). The CP includes: - Project description - CAA IRI involvement - Certification process schedule including project milestones - List of certification personnel - Type Certification (TC) basis - Test requirements - Environmental protection and operational requirements - Reference to the CCL to introduce the affected Certification Specification paragraphs and selected Means of Compliance (MC). (see subpart 6.1 for MC detailed description). - List of compliance documents - List of technical and operational manuals’ supplements Type Certification basis consist of: - the applicable airworthiness code including amendment established by CAA IRI effective on the date of application, - any special conditions in accordance with Part 21.A.16B(a), and - any Certification Specification not complied with that, is compensated for by factors that provide an equivalent level of safety. After approval by HOA and acceptance by the CAA IRI, the certification program is the binding working paper to demonstrate compliance to the relevant CS and environmental protection requirements. For the CP, form AMN-DO-F02 is used.

63. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.6 Compliance Check List (CCL) Page: 63 3.6 Compliance Check List (CCL) In order to guarantee at the end of the certification process that all in the Certification Program defined tasks were performed and all related certification documents and manuals are approved by the personnel defined in subpart 1.9 Authorization Table, a Compliance Check List (CCL) is established. The CCL is maintained by the Office of Airworthiness. The Office of Airworthiness shall also check if the Means of Compliance (MCs) being used correlate with the MC defined in the Certification Program. In case during the certification process, it turns out that the defined MCs are not sufficient; the CCL and CP shall be corrected accordingly. The new issues have to be again checked and approved by the Head of Office of Airworthiness. The MC shall be defined for each airworthiness and environmental protection requirement. When all related tasks are closed, Head of Office of Airworthiness approves the CCL. The CCL is the basis for the Declaration of Compliance. (see subpart 3.7). For the Compliance Check List, form AMN-DO-F03 is used.

64. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.7 Declaration of Compliance Page: 64 3.7 Declaration of Compliance After completion and acceptance of all certification specification and environmental protection requirements, the Office of Airworthiness issues the Declaration of Compliance. The completion is tracked with the Compliance Check List. (see subpart 3.6).  Minor Change: For Minor changes; the Declaration of Compliance is part of the Approval sheet (see form AMN-DO-F12). HOA approves the minor changes.  Major Change: For Major changes (STC is to be issued by CAA IRI), form AMN-DO-F11 is used. In this case the Declaration of Compliance will be provided to the CAA IRI. The Head of Design Organization (HDO) signs the Declaration of Compliance for the Major changes, and confirm that: - the type change investigation is completed, - the changed product complies with the applicable Certification Specification, Type Certification Basis and environmental protection requirements, and - the applicable procedures and processes as specified in the DOH have been followed.

65. Design Organization Handbook Issue: 02 Revision: 00 Part 3 : Changes to Type Certificate Date: Oct. 2022 Doc Code.: AMN-DOH 3.8 Approval of Changes Page: 65 3.8 Approval of Changes 3.8.1 Approval of Minor Changes The approval of a Minor change is pronounced on the basis of a completed type change investigation. Therefor the Compliance Check List (CCL) is used (see also subpart 3.6). The Approval of Change refers to the CCL (form AMN-DO-F03). When the CCL is approved, the Head of Office of Airworthiness (HOA) approves the Minor change by using the form AMN-DO-F12. 3.8.2 Approval of Major Changes On the basis of the completed Compliance Check List (CCL) (see also subpart 3.6) the Head of Design Organization (HDO) states the Declaration of Compliance (see subpart 3.7). For this purpose, form AMN-DO-F11 is used. The Head of Office of Airworthiness (HOA) sends this document to the CAA IRI. In case all type investigation documents are correct and completed, the CAA IRI will issue the approval sheet for the Major design change which is called Supplemental Type Certificate (STC). The Master Document List (MDL) is an index form, which lists all of the documents/drawings prepared in a change to type certificate project. See form AMN-DO-F10. The MDL will be attached to the Declaration of Compliance.

Design Organization Handbook Issue: 02 Revision: 00 Part 4 : Repairs Date: Oct. 2022 Doc Code.: AMN-DOH 4.1 Overall Workflow Page: 67 4 Repairs 4.1 Overall Workflow The below diagram indicates the overall workflow of repair design activities. Figure 6 - Overall work flow of repair design activities in Ameen Design Organization

68. Design Organization Handbook Issue: 02 Revision: 00 Part 4 : Repairs Date: Oct. 2022 Doc Code.: AMN-DOH 4.1 Overall Workflow Page: 68 The Ameen Design Organization controls and manages all aspects of the repair design including description of damage and repair, classification of repair, development and design, certification, embodiment and continued airworthiness in service. The CAA IRI is given full access to all parts of DAS and all documents and test programs as well as full access to design suppliers. Here, a brief description on sequence steps of above diagram is given: 1. The HDO is responsible for describing the damage and specifying the repair to be developed. For further details, see subpart 4.2, 4.3 and 4.4. 2. The design process can start at this point. For further details, see part 5. The documents for repair design (specifications, drawings, bill of material, production and installation procedures, etc.) are prepared. 3. The HOA together with the CVEs are preparing the classification including the substantiation for it. The HOA is responsible for the preparation and will approve it (form AMN-DO-F01B). For further details, see subpart 4.5. 4. The HOA is defining the type certification basis (see subpart 4.6) and together with the CVEs they are preparing the CP. The CP for repairs is a part of repair approval. The HOA is responsible for the preparation of the CP and will approve it (form AMN-DO-F02). For further details, see subpart 4.7. 5. The HOA is filling out the major change application form and sending it to CAA IRI. The application for a major change shall be accompanied by an overview drawing of the change including preliminary basic data like proposed operating characteristics and limitations. The HDO should check and sign the form. 6. CAA IRI will allocate a project/folder No. and will inform the Ameen’s DO by the responsible Project Control Manager (PCM). The PCM checks the CP and will accept it or will ask for revision. 7. The design engineer prepares the compliance demonstration document according to the certification program (analysis, compliance statements, reports, etc.). For further details, see part 6. 8. For tests (ground test, laboratory test and flight tests if applicable) see subpart 6.3.
