k. Allow conditions to stabilize and record the
(4) ENG PTIT.
l. Recover the engine not being tested.
(1) Engine passes test if the PTIT recorded
in paragraph K.k.(4) is less than or
equals to the MAX temperature limit
from figure 5-13 and recorded N1 speed
is equal to or less than the maximum N1
speed from figure 5-14 (Refer to
(2) Record the TEMP MARGIN VALUE by
subtracting the recorded PTIT found in
paragraph K.k.(4) from the MAX
temperature limit from figure 5-13 (e.g.
Recorded PTIT is 872. 899-872=27
TEMP MARGIN VALUE).
m. Return to step e, if required.
