The numbering system will be explained later in more detail. On document level, the manual is subdivided into five parts, named A to E. The designation and content of each part is listed below:  Part A: Introduction and Declarations This section. Explains the basic concept, handling of this manual, its structure according to the ATA100 numbering system, abbreviations and acronyms.  Part B:Master Servicing Manual (ATA Chapters 00 to 20) General description of the aircraft, basic definitions and standard procedures, tools, spares, airworthiness limitations, time limits, inspections and checks. Briefly, part B describes 8what is to be done, and when9.  Part C: System Description Section (ATA Chapters 21 to 90) Part C describes all aircraft systems, following the ATA100 numbering system.  Part D: Diagrams and Charts Part D contains diagrams and charts, if necessary in special sizes or as fold-outs.  Part E: Maintenance Job Cards Job Cards are collected in Part E. Note that the footer of Part E does not spell out to the part9s designation, but just shows part and the job index of the referred maintenance task according to the ATA100 numbering system. Briefly, Part E describes 8how something has to be done9. ATA100 Numbering System ATA100 – Chapter Code The Air Transport Association (ATA) Standard 100 numbering system is a widely accepted standard that provides a 6 digit numbering system to identify aircraft systems, subsystems and individual components in a structured, hierarchical approach. The first or leftmost pair of digits defines the Chapter, respectively system. The next pair of digits refers to the subsystem. The third pair of digits specifies a unit. Only complex systems use unit numbers. In case of simple systems, all information is contained in the main chapter and there is no subsystem or unit breakdown. The ATA100 numbering system and the corresponding system designations were adopted where ever possible and rational. In some cases the wording and nomenclature was adapted to match the design specifics of a gyroplane in best possible way. Due to its high degree of system integration, some systems cannot clearly be assigned to a single function. In this case the system or component was categorized by its main function. Example: the pneumatic trim cylinder also acts as brake in its secondary function. Chapter 02 has been modified to contain <TOOLS, SPARES AND CONSUMABLE MATERIALS=.

Except for counting of smaller numbers, calibrated measurement devices are needed. Monitor To watch a parameter or item over a certain period of time in order to read an exact value, derive a trend or identify a change caused by an event. Example: monitor rotor speed indication, monitor RPM drop Nick A dent with sharp edges (see also ‘dent) re-torque Refer to procedure ‘torque-tighten’. In contrary to procedure ‘torque check’ attachment hardware may rotate during re-torqueing Record (noun) Technical name for a documentation that shows the accomplishment of maintenance tasks or other activities, usually stating the responsible person’s name and date of compliance record (verb) To make an (official) entry in a maintenance record remove securing Cut open and remove split pins, lock wire, and such. Wear eye protection. Hardware Hold securing hardware with other hand to prevent particles from darting around. Collect all splinters and particles of securing hardware and discard. Replace To remove an unserviceable item and install a serviceable in the same location Servicing Simple tasks such as lubrication and cleaning, checking and adjusting of air tire pressure, replenishing of fluids Set To change (or verify) status of equipment to a given parameter, condition or mode. Example: set altimeter sub-scale to 1013 hPa torque-check Refer to procedure ‘torque-tighten’. Check with the (minimum) torque value supplied. Attachment hardware must NOT turn! If rotation of attachment hardware was noticeable the torque check FAILED. Refer to procedure described in Job Card torque-tighten Use a calibrated tool with the correct range and handle properly and carefully. Set tool to minimum torque (if min. and max. torque values are provided). Use stretched fingers at the long end of the tool and counterhold directly at the pivot point. Click-Type: Stop upon the first clicking. If multiple clicking is heard or further rotation is suspected, open/unscrew and repeat. Replace attachment hardware if appropriate. In order to align attachment hardware (for example in case of a split pin) adjust tool to the maximum allowed torque and tighten carefully until hardware aligns. NO clicking must be heard! If clicking was heard, redo the complete procedure while trying different attachment hardware and/or in different installation position. Verify Check that a certain dimension or condition, or set of these, is in-line with given specifications. In order to do so, a special (measurement) procedure will be required and the reference to comply with will be specified.

Trained partners with the correct tooling are permitted to change the bearing. Status and lifetimes of components, liquids and fluids is listed in the Event and Configuration Log form. The initial Event and Configuration Log is delivered with the gyroplane by AutoGyro. An empty form is provided for download on the AutoGyro website. Primary and Secondary structure determination: A primary structural part is one for which the failure would be catastrophic and would prevent continued safe flight and landing. All other structure can be considered as Secondary, thus failure of a Secondary structural part would not be immediately catastrophic and with due care continued safe flight and/or a safe precautionary landing could still be made. Because of the simplicity of the aircraft structure some parts have a dual role – such as the airframe. As an example, the airframe of the aircraft is primary structure, yet it carries attachment point for items non flight critical components. The primary structural elements are considered to be:  Airframe  Connection assemblies joining the rotor head to the mast.  The rotor assembly and rotor head  The tail and rudder assembly  The rudder and rotor control system  The main undercarriage and nosegear  Whilst other items may have an effect on flight safety, they are considered secondary to the above. The undercarriage is included, as whilst it does not contribute to safe flight, it is difficult to make a safe landing without it – inevitably an aircraft rollover would result, probably destroying the aircraft.

Event / Occurrence / Unusual Condition Action / Reference Rotor vibration see CHAPTER 18 Propeller vibration see CHAPTER 18 If in doubt contact AutoGyro Technical support. 05-50-00 Conditional Inspections Depending on the conditions the gyroplane is operated in or special operational incident the following conditional inspection may apply: 05-51-00 Inspections - Special Operational Conditions Condition Action / Reference Operation in sand or dust see below AVGAS engine manufacturer documentation Winter operation see below Operation in sand or dust  Refer to engine manufacturer documentation  Inspect/change air filter regularly  Reduce 100 hrs inspection interval to 50 hrs  Apply propeller leading edge protection strip  Operation with keel tube fin (recommended) Winter operation The cooling system for the cylinder heads of the engine is filled with a mixture of Ethylene Glycol anti- freeze and distilled water, which gives freezing protection down to -20°C. Using a hydrometer, check protection temperature of the coolant and add anti-freeze, if necessary. If temperatures are expected to fall below protection temperature, drain the coolant, and if required for service, refill with pure antifreeze (see 12-30-40 Servicing: Engine Coolant). CAUTION Pure antifreeze is not as good an engine coolant as a 50/50 mix with water. Take care that engine coolant limits are not exceeded. As soon as ambient temperatures permit, drain and refill with the normal coolant mix. Because the oil and coolant system contain a thermostat, operation in winter does not require part- blocking of the radiators to maintain temperatures Aircraft Maintenance Manual AutoGyro MTOsport 2017 915 iS / 916 iS AMM-M7-915iS/916iS-EN- B-2024-05 Part B – Master Servicing Manual (Chapter 00 – 20) Page 15 of 23 05-55-00 Inspections - Special Operational Incident Event / Occurrence / Unusual Condition Action / Reference Suspected hard landing see below Rotor contact with obstacle see below Propeller contact with obstacle or external impact see below Birdstrike see below Lightning strike see below Suspected hard landing In case of a suspected hard landing perform the following checks:  Inspect nose gear, attachment, fork, linkage and wheel bearing  Inspect main gear axles and attachment  Examine possible rotor / propeller strike  see ‘Rotor / propeller contact with obstacle’  CRITICAL: Inspect main gear suspension bow (airframe attachment and both axle attachments ok, no cracks)  CRITICAL: Inspect airframe and attachment points for possible deformation or cracks, esp engine mountings. Perform levelling procedure (see Job Card 08-20-00 2-1 in Part E of this manual)  CRITICAL: Inspect engine mounting and propeller to frame clearance approx. 5 cm  CRITICAL: Perform a rotor alignment check Defective components must be replaced. In case one or more of the items marked ‘CRITICAL’ are found defective or out of tolerance, contact AutoGyro customer support. Rotor contact with obstacle Rotor contact with obstacle include any rotor strike of the standing or turning rotor with an obstacle, including propeller and fuselage structures. In case of rotor contact with obstacle:  Perform a rotor alignment check and adjust, if necessary  Examine damage of aluminium rotor profile:  allowed damage: dent with max. depth of 1 mm  CRITICAL damage: nick(s)  In case the turning rotor hit the stabilizer/rudder, a detailed inspection of the affected components must be performed. In case CRITICAL damage is found, the rotor system must be replaced. Contact AutoGyro Technical Support. Propeller contact with obstacle or external impact Refer to engine manufacturer documentation. If there is no visible damage, then perform tap test on propeller blades to assess for invisible damage. Replace damaged parts. Birdstrike  Perform detailed inspection of all affected component  If rotor blades are affected, proceed according to ‘Rotor contact with obstacle’  If propeller is affected, proceed according to ‘Propeller contact with obstacle or external impact’ Aircraft Maintenance Manual AutoGyro MTOsport 2017 915 iS / 916 iS AMM-M7-915iS/916iS-EN- B-2024-05 Part B – Master Servicing Manual (Chapter 00 – 20) Page 16 of 23 Lightning strike A lightning is likely to have caused invisible damage to many components, especially the main rotor bearing.

CHAPTER 08 - LEVELING & WEIGHING Weighing shall be performed in a draft-free hangar on level ground, with the aircraft defueled to minimum useable fuel. Make sure each wheel of the gyroplane is located centred on the scales. The weighing report is available for download. CHAPTER 09 - TOWING & TAXIING Experience shows that aircraft may be exposed to much higher loads when operated on ground, than when in flight. Such loads caused by rumbling on rough terrain, or bouncing the aircraft over the hangar threshold may easily exceed the design load in peak. Use caution when handling the gyroplane on ground. Care must be taken when pushing at the rudder or at the outer stabilizers. Avoid excessive swing of the rotor blades as repeated bending ultimately leads to fatigue or damage. CHAPTER 10 - PARKING, STORAGE & RETURN TO SERVICE Parking up to 6 months No special measures need to be taken. NOTE Don´t let E10 remain in the fuel system for unnecessary long time or for long- term storage! Parking more than 6 months  Refer to engine manufacturer documentation  Maintain battery charged  Unload wheel gear  Cover aircraft with a light plastic tarpaulin or cloth Long-term Storage Contact AutoGyro Technical Support Return to Service Perform a 100 hrs Inspection.

Therefore, the gyroplane should be cleaned after every last flight of the day or more often, if environmental conditions dictate. In order to protect the gyroplane against dirt, dust, bird soil, and sunlight, the aircraft should be covered with a light plastic tarpaulin or cloth. Openings to the engine, service access ports and airspeed indicator should be closed after the flight (insects, birds etc.). Contamination can be cleaned with clean water, possibly with mild cleaning additives. To clean the rotor it is best to soak contamination with a cloth or towel, wipe with soft or micro-fibre cloth, and rinse thoroughly with water. 12-20-00 Lubrication Component Application Reference Lubrication: Teeter hinge 5 hrs (recomm.) see below Lubrication: Pre-rotator drive coupling sleeve as required see below See CHAPTER 05 for respective time limits. Lubrication: Teeter hinge The teeter hinge consists of a steel bolt running in special Teflon coated bushings. In order to provide proper bearing action and to avoid wear and bearing play, which will cause rotor vibration in consequence, regular lubrication is essential. In order to do so, the best practise is to perform work steps 5 to 7 from Job Card 62-11-00 6-1 INSPECTION: ROTOR – TEETERING PARTS in Part E of this manual. Make sure to apply grease also on the outer (secondary) bearings inside the teeter tower. Lubrication: Pre-rotator drive coupling sleeve Apply a thin layer of lubricant AG-LUB-03 on coupling sleeve when in extended position in regular intervals, at latest when the sliding surface feels dry or after flight through rain. Mast cover must be removed! 12-30-10 Servicing: Engine Air Filter The air intake filters need to be replaced or cleaned according to the manufacturer‘s recommendation. Depending on environmental conditions, such as dust, sand, or pollution the recommended rate of maintenance should be increased as required. Engine cowling must be removed! 12-30-20 Servicing: Tire Pressure Main wheels 1.8 – 2.3 bar Nose wheel 2.0 – 2.4 bar NOTE: Green valve caps are used when the tire is filled with nitrogen. Aircraft Maintenance Manual AutoGyro MTOsport 2017 915 iS / 916 iS AMM-M7-915iS/916iS-EN- B-2024-05 Part B – Master Servicing Manual (Chapter 00 – 20) Page 21 of 23 12-30-30 Servicing: Battery The aircraft is fitted with a maintenance-free gel electrolyte battery. Maintenance is therefore limited to outside soundness, correct attachment, and cleaning. Check integrity of the battery as leaking fluid contains corrosive sulphuric acid which would lead to extensive damage when contacting the framework and attachments. Charge the battery only with a charging device which is suitable for gel electrolyte batteries. CAUTION: The battery must never be deep discharged, as it will be damaged. If so, it might need to be replaced. 12-30-31 Servicing: ETX 900 Lithium LiFePO5 Earth X Battery The Lithium battery is a maintenance free battery. EarthX lithium battery has over discharge protection via an internal Battery Management System (BMS) to disconnect the battery from the active load (your vehicle) to protect the cells from damage when it is 95-98% drained. Inspection or testing is not needed for 24 months after purchase, and thereafter the following is recommended annually:  Follow any inspection requirements for the battery type as documented by the battery manufacturer, found on the manufacturers website.  Visually inspect the battery for signs of damage; plastic case is warped or swollen.  Check the fault indicator mounted on the upper side of the battery, and/or located in the instrument panel LEDs, a solid or flashing warning indicates a variety of defects as below.  Ensure the terminal screws are tight (properly torqued) Charge the battery only with a charging device which is suitable for Lithium batteries. 12-30-40 Servicing: Engine Coolant The cooling system for the cylinder heads of the engine is filled with a mixture of anti-freeze and water, which gives freezing protection down to -20°C. Check protection temperature of the coolant and add anti-freeze, if necessary. Verify coolant level in the expansion tank, replenish as required. Minimum fluid level is stated (engraved) on the fuel dipstick.If no fluid is visible on the dipstick, a technical defect is most probable. Have engine inspected before next flight. If temperatures are expected to fall below protection temperature, refer to 05-51-00 Winter operation. Note! The coolant system contains a complex pathway of hoses to each cylinder head. Take care to ensure the system is properly vented during refilling. With the Rotax header tank cap removed (and only with a cold engine), adequate venting may be ensured by sharply squeezing the radiator hoses until no air bubbles exit through the tank. Refit the cap after venting. 12-40-00 Replenishing / Replacement of Fluids Liquid / Fluid Max. Filling Qty. Type / Code Engine coolant (50/50 distilled water and EthyleneGlycol antifreeze suitable for aluminium engines) 3.8 ltr as documented Engine Oil 3.4 ltr as documented See CHAPTER 05 for respective time limits.

Finding out the cause for vibration and its proper cure requires experience and special equipment. This is why vibration analysis and related maintenance can only be performed by specialized service partners, or AutoGyro GmbH, Germany directly. The following tests or fault isolation procedures should be performed in order to exclude systematic errors in case of rotor vibration:  rotor system cleanliness  check/verify correct installation position of the shim washers relative to teeter block and teeter tower (one or two dot markings on block, shim washer and teeter tower must align)  check for possible play in teeter bearing in axial or radial direction  check rotor system alignment (see Job Card 62-11-00 5-1 in Part E of this manual)  check for possible play in rotor bearing  adjust (increase) rotor control friction (see Job Card 62-32-00 5-1 in Part E of this manual) In case of unusual vibration, contact AutoGyro or an AutoGyro specialized service partner. If possible, try to describe the type of vibration as precise as possible as this will help to save time to reproduce and troubleshoot, or even allow a first remote assessment. The following table provides a basic classification. Vibration appearance / sensation / parameter  Lateral (left-right / back-forth) vibration with approximately 6 per second amplitude  Vertical (up-down) vibration with approximately 12 per second amplitude  Free-stick movement – carefully release control stick (if possible/safe) and describe path and displacement of control stick head  Flight condition (weight, speed) with highest vibration level  Rotor RPM  Higher frequency vibration (around 50 Hz, like an electric razor), changing with RPM  Higher frequency vibration, frequency and amplitude significantly changing with power setting, possibly irregular or erratic  RPM or power setting with highest vibration levels Aircraft Maintenance Manual AutoGyro MTOsport 2017 915 iS / 916 iS AMM-M7-915iS/916iS-EN- B-2024-05 Part B – Master Servicing Manual (Chapter 00 – 20) Page 23 of 23 Noise is mainly created by the propeller. Engine and muffler play a secondary role in noise emission, as long as intact. Any deficiencies could be easily identified by a visual inspection or tap test. Repair or replace as necessary. Propeller noise is emitted by the fast turning blade tips and usually increases exponentially with RPM and speed due to interaction of air disturbances with the blade tips. As noise is a subjective perception, only measurement will provide reliable data. However, the following table provides elements and countermeasure to troubleshoot and cure in case of unusual noise emission. Possible causes for noise / countermeasures  Check propeller condition (cleanliness, erosion, damaged or splintered blade tips). Clean or repair propeller.  Check propeller RPM during take-off (full throttle) or cruise. Adjust/reduce if required.  Check/adjust propeller pitch. Check pitch setting of individual blades and adjust so that they are the same.  Check leading edge of propeller and leading edge protection strip (if installed). A damaged leading edge protection strip (loose or sticking out end) may change noise signature significantly. Replace as necessary.  Check air filter condition and installation condition.  Check exhaust system for soundness CHAPTER 19–20 – UNASSIGNED / N/A Aircraft Maintenance Manual AutoGyro MTOsport 2017 915 iS / 916 iS AMM-M7-915iS/916iS-EN- C-2024-05 Part C – System Description Section (Chapter 21 – 90) Page 1 of 37 Contents CHAPTER 21 UNASSIGNED / N/A 3 CHAPTER 22 UNASSIGNED / N/A 3 CHAPTER 23 COMMUNICATIONS 3 23-10-00 Speech Communication / Radio 3 23-40-00 Interphone / Intercom 3 CHAPTER 24 ELECTRICAL POWER 3 24-30-00 DC Generation and Battery 4 24-60-00 DC Electrical Load Distribution 4 CHAPTER 25 EQUIPMENT / FURNISHINGS 6 25-10-00 Flight Compartment 6 CHAPTER 26 FIRE PROTECTION / FIRE WARNING 6 CHAPTER 27 FLIGHT CONTROLS 7 27-00-00 Flight Controls 7 27-20-00 Flight Controls – Rudder 7 CHAPTER28 FUEL 8 28-10-00 Storage 8 28-20-00 Distribution 8 28-40-00 Indicating 9 CHAPTER 29 UNASSIGNED / N/A 9 CHAPTER 30 UNASSIGNED / N/A 9 CHAPTER 31 INDICATING SYSTEM 9 31-10-00 Instruments & Control Panels 9 31-60-00 Integrated Display Systems 22 CHAPTER 32 LANDING GEAR 22 32-10-00 Main Gear 22 32-20-00 Nose Gear 22 32-40-00 Wheels and Brakes 22 CHAPTER 33 LIGHTS 23 33-40-00 Exterior 24 CHAPTER 34 NAVIGATION 24 34-10-00 Flight Environment Data 24 34-20-00 Attitude and Direction 24 34-70-00 ATC Transponder 24 CHAPTER 35 UNASSIGNED / N/A 24 CHAPTER 36 PNEUMATIC 24 36-11-20 Generation / Compressor 24 36-21-00 Distribution 24 CHAPTER 37- UNASSIGNED / N/A 25 CHAPTER 50 UNASSIGNED / N/A 25 CHAPTER 51 STANDARD PRACTICES – STRUCTURES 25 CHAPTER 52 DOORS, COVERS AND COWLINGS 25 52-10-00 Passenger / Crew 25 52-40-00 Service Covers and Cowlings 25 CHAPTER 53 FUSELAGE 25 CHAPTER 54 UNASSIGNED / N/A 25 CHAPTER 55 STABILIZERS 26 55-40-00 Rudder 26 CHAPTER 56 WINDOWS 27 56-10-00 Flight Compartment / Windshields 27 CHAPTER 57 - UNASSIGNED / N/A 27 CHAPTER 60 UNASSIGNED / N/A 27 CHAPTER 61 PROPELLER 27 61-10-00 Propeller Assembly 27 61-20-00 Controlling 27
