ENGINE AND HYDRAULIC
EMERGENCY PROCEDURES
NOTE: In the unlikely event of an ECA failure in a full

trim condition, fuel flow will be reduced: the EGT and

rpm will decrease, and the thrust available will be

governed by the maximum rpm obtained. The thrust may

be reduced as much as one third of the normal full

throttle value. Very low idle rpm may occur, and the
throttle must be handled carefully to avoid stall or
flameout.
NOTE: ECA total failure will, in most instances, result in
a no-trim condition, increasing the rpm and EGT. The
EGT and rpm must be controlled carefully within limits by
throttle manipulation. Do not exceed 90% above
20,000 feet, or 95% below 20,000 feet.
