Basis entries as written on the TCDS

1. REG

   JAR 25, Change 11, dated 17.03.1986

   Not linked to provisions yet: the line is not interpreted, or its document is not in the dataset.

2. EXEMPT

3. EXEMPT

   - JAR 25.672 (a) Only the condition of automatic bank control circuit is enunciated on the central warning display. Drop of pressure in the hydraulic system is indicated by a pressure gauge. Correct function of electrical circuit is checked before take-off by means of a TEST pushbutton.

4. EXEMPT

   - JAR 25.677 (b) For the aileron trim tab the neutral position is only enunciated. The Aeroplane Flight Manual requires that the neutral position must be checked before taxiing-out for take- off.

5. EXEMPT

   - JAR 25.679 The control surfaces can only be locked on the ground, by means of clamps. These locking devices are conspicuously marked by red flags.

6. EXEMPT

   - JAR 25.703 A yellow light on the central warning display annunciates that the wing flaps are not in the take-off position. Parking brake release is indicated by the position of the control lever and a change in pressure gauge reading.

7. EXEMPT

   - JAR 25.777 (e) The wing-flap control is located level with the landing gear control.

8. EXEMPT

   - JAR 25.777 (f) The landing gear control is not located of the throttles, but aft of the throttles.

9. EXEMPT

   - JAR 25.853 (c) The test in compliance with this requirement was not conducted.

10. EXEMPT

    - JAR 25.1305 (c) A fuel flow meter indicator is not included in the fuel system for each engine. The engine power setting is sufficiently characterized by the indicated engine parameters.

11. EXEMPT

    - JAR 25.1305 (c) (8) There is no indication of proper functioning of the fuel heater. Warm oil passes through the heater continuously.

12. EXEMPT

    Note: Fuel heater was removed from type design by TDC ZTN 001, TDC ZKB 53 210 and TDC ZKB 53 689 for the airplanes manufactured after August 12/2009.

13. EXEMPT

    - JAR 25.1305 (e) (3) Each propeller blade position below the minimum flight pitch is indicated.

14. EXEMPT

    - JAR 25.1326 (a)Operation of the pitot heating system is indicates by a green light. When the system is not operating, for any reason, the green light extinguishes.

15. EXEMPT

    - JAR 25.1337 (a) (2) Instrument lines and hoses have 4 mm inner diameter, which reduces the risk of escape of excessive fluid if the line fails.

16. EXEMPT

    - JAR 25.1435 (a) (2) A means to indicate hydraulic fluid quantity is not installed. The hydraulic system is a closed circuit, which is not connected with the atmosphere. Hydraulic fluid leakage could only occur in the event of a failure of some system component. In such a case a separate emergency system can be used.

17. ELOS

    For those exemptions specified in item 4 above appropriate measures were accepted showing, as a minimum, the same level of safety. These measures form parts of the certification data.
