NOTE 7. Engine ratings : are based on calibrated rig with the performance under the following conditions:
- Static, sea level standard conditions (59°F, 29.92 Hg.)
- No air bleed, no power off-takes
The indicated ratings are minimum acceptable final test performance of series and overhauled engines, measured
with:
- Calibrated test bed air intake, straight, short exhaust pipe, 10.25 in. dia.
  (For complete performance diagram, see Turbomeca Operation Manual 268.08.931).
NOTE 8. The engine has no provision for principal fuel supply filtering.  Fuel supply from aircraft (helicopter) system must
therefore be delivered to engine with a 15 microns filtration grade.
Maximum fuel flow:  63.4 U.S. gallons/hour.
NOTE 9. The Astazou III A has integral oil system, including oil tank, oil pumps, filter, all necessary piping and fittings,
(except oil cooler, which is helicopter delivery).

0.268.16.518.0
- Oil filter (part of the accessory drive casing) including cleanable
metallic filter-element with a 30 microns filtration grade: Sofrance, Type P5315A
- Oil tank volume, including air expansion space: 3.86 U.S. gal
- Oil volume at top of show-glass (filled): 2.43 U.S. gal
- Oil volume at lowest show-glass (minimum indication): 1.64 U.S. gal
- Demonstrated usable oil volume: 1.32 U.S. gal
- Undrainable oil volume (approx.)   .40 U.S. gal
- Oil consumption, normally negligible, but less than:   .21 U.S. pint/hour
maximum allowable: 1.05 U.S. pint/hour
- Maximum acceptable fuel dilution in oil: 10 percent in volume
NOTE 10. Engine monitoring transmitters:
The engine is equipped with the following transmitter instruments:
(a) Tachometer transmitter (turbine speed): KOLLSMAN Type L827.80-00-010
(b) Low oil pressure alarm pressure switch: TURBOMECA 0.076.46.506.0 or 507.0

E14EU 4
