b) Endurance. Tests of sufficient duration shall be conducted at such powers, speeds and other operating conditions as are necessary to demonstrate reliability and durability of the propeller. 2007/70/II. szám ANNEX 8 IIIA-7-1 2/3/04 CHAPTER 7. POWERPLANT INSTALLATION 7.1 General 7.1.1 Applicable Standards The powerplant installation shall comply with the Standards of Chapter 4 and with the Standards of this chapter. 7.1.2 Compliance with engine and propeller limitations The powerplant installation shall be so designed that the engines and propellers (if applicable) are capable of being used in the anticipated operating conditions. In conditions established in the aeroplane flight manual, the aeroplane shall be capable of being operated without exceeding the limitations established for the engines and propellers in accordance with Chapters 5, 6 and 7. 7.1.3 Control of engine rotation In those installations where continued rotation of a failed engine would increase the hazard of fire or of a serious structural failure, means shall be provided for the crew to stop the rotation of the engine in flight or to reduce it to a safe level. 7.1.4 Engine restarting Means shall be provided for restarting an engine at altitudes up to a declared maximum altitude. 7.2 Arrangement and functioning 7.2.1 Independence of power-units The powerplant shall be arranged and installed so that each power-unit together with its associated systems is capable of being controlled and operated independently from the others and so that there is at least one arrangement of the powerplant and systems in which any failure, unless the probability of its occurrence is extremely remote, cannot result in a loss of more power than that resulting from complete failure of the critical power-unit. 7.2.2 Propeller vibration The propeller vibration stresses shall be determined and shall not exceed values that have been found safe for operation within the operating limitations established for the aeroplane. 7.2.3 Cooling The cooling system shall be capable of maintaining powerplant temperatures within the established limits (see 7.1.2) at ambient air temperatures up to the maximum air temperature appropriate to the intended operation of the aeroplane. The maximum and, if necessary, minimum air temperature for which the powerplant has been established as being suitable shall be scheduled in the aeroplane flight manual. 7.2.4 Associated systems The fuel, oil, air induction, and other systems associated with the powerplant shall be capable of supplying each engine in accordance with its established requirements, under all conditions affecting the functioning of the systems (e.g. engine power, aeroplane attitudes and accelerations, atmospheric conditions, fluid temperatures) within the anticipated operating conditions. 7.2.5 Fire protection For regions of the powerplant where the potential fire hazards are particularly serious because of the proximity of ignition sources to combustible materials, the following shall apply in addition to the general Standard of 4.1.6 e).
