The Civil Aviation (Operation of Aircraft - Commercial Air Transport) Regulations, 2024

1.3 To minimise the probability of in-flight engine failure, the engine shall be equipped with: (a) an ignition system that activates automatically, or is capable of being operated manually, for take-off and landing, and during flight, in visible moisture; (b) a magnetic particle detection or equivalent system that monitors the engine, accessories gearbox, and reduction gearbox, and which includes a flight deck caution indication; and (c) an emergency engine power control device that permits continuing operation of the engine through a sufficient power range to safely complete the flight in the event of any reasonably probable failure of the fuel control unit.

2.0 SYSTEMS AND EQUIPMENT Single-engine turbine-powered aeroplanes approved to operate at night and/or in IMC shall be equipped with the following systems and equipment intended to ensure continued safe flight and to assist in achieving a safe forced landing after an engine failure, under all allowable operating conditions- (a) two separate electrical generating systems, each one capable of supplying all loads for probable combinations of continuous instruments, equipment and systems required at night and/or in IMC; in-flight electrical (b) a radio altimeter; (c) an emergency electrical supply system of sufficient capacity and endurance, following loss of all generated power, to as a minimum-: (i) maintain the operation of all essential instruments, communication and navigation systems during a descent from the maximum certificated altitude in a glide configuration to the completion of a landing; flight (ii) lower the flaps and landing gear, if applicable; (iii) provide power to one pitot heater, which must serve an air speed indicator clearly visible to the pilot; (iv) provide for operation of the landing light specified in paragraph 2 (j); (v) provide for one engine restart, if applicable; and (vi) provide for the operation of the radio altimeter; 213 Civil Aviation (Operation of Aircraft – Commercial Air Transport) GN. NO.12 (Contd.) (d) two attitude indicators, powered from independent sources; (e) a means to provide for at least one attempt at engine re-start; (f) airborne weather radar; (g) a certified area navigation system capable of being programmed with the positions of aerodromes and safe forced landing areas, and providing instantly available track and distance information to those locations; (h) for passenger operations, passenger seats and mounts which meet dynamically tested performance standards and which are fitted with a shoulder harness or a safety belt with a diagonal shoulder strap for each passenger seat; in pressurised aeroplanes, sufficient supplemental oxygen for all occupants for descent following engine failure at the maximum glide performance from the maximum certificated altitude to an altitude at which supplemental oxygen is no longer required; (i) (j) a landing light that is independent of the landing gear and is capable of adequately illuminating the touchdown area in a night forced landing; and (k) an engine fire warning system.

3.0 MINIMUM EQUIPMENT LIST The Authority shall require the minimum equipment list of the operator approved in accordance with Civil Aviation (Air Operator Certificate) Regulations to specify the operating equipment required for night and/or IMC operations, and for day/VMC operations.

4.0 FLIGHT MANUAL INFORMATION The flight manual shall include limitations, procedures, approval status and other information relevant to operations by single-engine turbine-powered aeroplanes at night and/or in IMC.

5.1 The operator approved for operations by single-engine turbine-powered aeroplanes at night and/or in IMC shall report all significant failures, malfunctions or defects to the Authority who in turn will notify the State of design.

5.2 The Authority shall review the safety data and monitor the reliability information so as to be able to take any actions necessary to ensure that the intended safety level is achieved. The Authority will notify major events or trends of particular concern to the appropriate type certificate holder and the State of design.

6.1 Operator route planning shall take account of all relevant information in the assessment of intended routes or areas of operations, including the following- (a) the nature of the terrain to be overflown, including the potential for carrying out a safe forced landing in the event of an engine failure or major malfunction; (b) weather meteorological influences that may affect the flight; (c) other criteria and limitations as specified by the Authority.

6.2 The operator shall identify aerodromes or safe forced landing areas available for use in the event of engine failure, and the position of these shall be programmed into the area navigation system. seasonal and other adverse information, including 214 Civil Aviation (Operation of Aircraft – Commercial Air Transport) GN. NO.12 (Contd.) Note 1 - A ‘safe’ forced landing in this context means a landing in an area at which it can reasonably be expected that it will not lead to serious injury or loss of life, even though the aeroplane may incur extensive damage.

7.0 FLIGHT CREW EXPERIENCE, TRAINING AND CHECKING

7.1 The Authority shall prescribe the minimum flight crew experience required for night/IMC operations by single-engine turbine-powered aeroplanes.

7.2 The operator’s flight crew training and checking shall be appropriate to night and/or IMC operations by single- engine turbine-powered aeroplanes, covering normal, abnormal and emergency procedures and, in particular, engine failure, including descent to a forced landing in night and/or in IMC conditions.

8.0 ROUTE LIMITATIONS OVER WATER The State of the Operator shall apply route limitation criteria for single-engine turbine powered aeroplanes operating at night and/or in IMC on over water operations if beyond gliding distance from an area suitable for a safe forced landing/ditching having regard to the characteristics of the aeroplane, seasonal weather influences, including likely sea state and temperature, and the availability of search and rescue services.

9.0 OPERATOR CERTIFICATION OR VALIDATION The operator shall demonstrate the ability to conduct operations by single-engine turbine powered aeroplanes at night and/or in IMC through a certification and approval process specified by the Authority.
