6. Begin increasing thrust and increasing NO. 1 &
NO. 2 ENGINE BEEP TRIM switch until gas
producer (N1) speed for engine being TEACed
stabilizes at maximum and rotor rpm droops to
98 percent. Reduce thrust slightly to allow
RRPM to return to 100%. Note N1 then increase
thrust to droop RRPM to 98% without exceeding
limits. Verify N1 has not increased from that
7. Stabilize the rotor speed at 98 percent, then
record the following:
c. RRPM 98%.
d. Engine PTIT.
f. TRQ .
Do not move the ENGINE CONDITION lever of
the other engine from GROUND to FLIGHT un-
til N1 speed and torque of the engine being
TEACed has been reduced.
8. After completion of the check, reduce engine
power initially by operating the No. 1 & 2
ENGINE BEEP TRIM switch to decrease rotor
rpm, N1, and torque. Do not lower thrust unit
rotor rpm and N1 begins to decrease.
9. Move the ENGINE CONDITION LEVER of the
next engine to be TEACed from GROUND to
