I.
Fuel system malfunctions 1.8.1.2.6
Sg 1, fr 2
Lesson Organization
A. Main fuel system failure (Incorrect or uncommanded
engine response)
1.
Indications
a.
Abnormal engine behavior or loss of engine
control
b.
At a fixed throttle position, fluctuations in rpm
accompanied by fluctuations in thrust or an
uncommanded acceleration or deceleration
c.
During transient throttle operation, lack of
acceleration/deceleration or faster than normal
acceleration resulting in a surge
2.
Procedures - See NATOPS
B. ECA failure 1.8.1.1.9.1.2
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 ft, or 95% below 20,000 ft, do not exceed 600o C
EGT.
