4.4.2
Engine test run for maintenance purposes
(Real Time Log File (RTLF),
Internal Data Logger (IDL), Event Log (EL))
Make sure that the Force B switch is in the automatic position.
1.
Warm-up (in accordance with Section 4.3, Page 3 of this
Chapter)
•
Allow the engine to warm up for approximately
2 minutes at idle speed.
•
Then increase the propeller speed to 1400 rpm until
the oil temperature has reached 50° C and the coolant
temperature has reached 60°C.
2.
FADEC and propeller pitch functional check (in
accordance with Section 4.4.1, Page 3 of this Chapter)
3.
Check engine acceleration behavior and performance
•
Move the load selector quickly to the full-load position.
The propeller must accelerate smoothly and steadily
to the following propeller speed limits (rpm):
Single-engined ........................ 2240 rpm to 2300 rpm
Twin-engined........................... 2240 rpm to 2320 rpm
The load indicator must show more than 95%.
Maintain this status for 30 seconds, then return the
load selector to the idle position.
•
Move the Force B switch to the FADEC B position.
Move the load selector to the full-load position. The
propeller must accelerate smoothly and steadily to the
following propeller speed limits (rpm):
Single-engined ........................ 2240 rpm to 2300 rpm
Twin-engined........................... 2240 rpm to 2320 rpm
The load indicator must show more than 95%.
Note:
CD-135:
Propeller adjustment: 12° +0.2/-0
Turning nut by a full turn (360°) will produce a path of 1.5mm.
0.3mm are equivalent to one degree blade angle of the
propeller, one degree is equivalent to a change of 100 rpm.
Note:
CD-155:
Propeller adjustment: 13,5° +0.2/-0
Turning nut by a full turn (360°) will produce a path of 1.5mm.
0.3mm are equivalent to one degree blade angle of the
propeller, one degree is equivalent to a change of 100 rpm.
