TEO-540-A1A Engine Installation and Operation Manual

Table 1 (Cont.)

Action for Engine Conditions

Engine Condition

Explanation/Corrective Action

Annunciators (Cont.)

The NTO or TLO annunciator is
illuminated but can still make
rated power

(Indicates a component has failed
and has put the engine in a back-
up mode - any additional failure
can cause loss of power)

Complete a safe landing and speak to Maintenance to
isolate faults.

TLO annunciator illuminates
during flight

The current flight can continue for up to 20 hours as long
as no other annunciators are illuminated and there are no
other engine problems. After landing, speak to
Maintenance to isolate faults.

Annunciator fails

Have Maintenance replace the annunciator as soon as is
practical.

All annunciators fail

Have Maintenance examine all annunciators and wiring
as soon as possible.

“PFT in Progress” indication is
cleared while the PFT is in
progress

The PFT annunciator will flash as an indication that the
pre-flight test was not completed. The pilot must push
and then let go of the PFT button to clear this condition
and then re-start the pre-flight test.

Engine Operation

Engine roughness

Complete a safe landing and speak to Maintenance.

Engine hesitates, misses

Complete a safe landing and speak to Maintenance.

Low, high or surging rpm

Complete a safe landing and speak to Maintenance.

Low or fluctuating oil pressure

Complete a safe landing and speak to Maintenance, refer
to the section “Low Oil Pressure During Flight” in this
chapter.

Oil pressure falls below the
minimum level

Complete a safe landing. Refer to the section “Low Oil
Pressure During Flight” in this chapter.

High oil temperature

Complete a safe landing and speak to Maintenance.

High oil pressure

Before increasing the power control, allow the oil
temperature to increase.

Low or high fuel flow

Complete a safe landing and speak to Maintenance

Excessive manifold pressure

Complete a safe landing and speak to Maintenance.
