If N1 oscillations occur:
LAND IMMEDIATELY
Flashing at idle or during starting or shut down:
Fuel filter pre-clogging level 1 reached
WARNING FUEL FILTER BY-PASS OPENING LEADS TO CONTAMINATION OF THE FUEL LINES AND THE GOVERNOR, WHICH MAY INDUCE N1 OSCILLATIONS, LIMITED POWER OR EVENTUALLY FLAME-OUT.
One flight of 3 hours maximum flight time can be performed before maintenance action
DOOR (yellow light)
Airspeed ……………………………………. REDUCE to 70 KTS
LAND AS SOON AS PRACTICABLE
Descent and approach at low rate of descent
FILTER (yellow light)
NOTE: Certain conditions may cause “FILTER” to flicker
Corrective action should only be taken when Illumination is continuous
- Monitor TOT for any significant rise, i.e. >20 C
- Monitor engine conditions for any indications of degradation or compressor stall
- If rise in TOT or engine performance is unacceptable Open bypass door by pressing
“FILTER” switch “BYPASS” switch should illuminate and “FILTER” switch should extinguish indicating the bypass door is open and the pressure is back within normal
range.WARNING To prevent compressor erosion avoid (if possible) operation in dirty or dusty environment with the bypass door open
BYPASS (yellow light)
If the flight or landing environment has significant dirt or debris, it is recommended that the bypass door be closed, provided no rotorcraft or engine limits will be exceeded.
With the bypass closed, the “BYPASS” will extinguish and the “FILTER” will potentially reappear under high engine power settings until the filter has been cleaned
