Landing Without Elevator Control
The pitch trim spring cartridge is attached directly to the elevator and
provides a backup should you lose the primary elevator control
system. Set elevator trim for a 80 KIAS approach to landing.
Thereafter, do not change the trim setting until in the landing flare.
During the flare, the nose-down moment resulting from a power
reduction may cause the airplane to hit on the nosewheel. At
touchdown, bring the power lever to idle.
1. Control Yoke................................................... ATTEMPT TO FREE
Clasp both hands around the control yoke and pull straight back
and forth in a strong, steady, and continuous motion.
2. If no elevator control, attempt to use Trim System to control aircraft
pitch:
a. If Trim System inoperative or has no affect on aircraft pitch:
(1) Perform Forced Landing Checklist.
b. If Trim System affects aircraft pitch:
(1) Flaps ...................................................................SET 50%
(2) Trim...............................................................SET 80 KIAS
(3) Power .......................AS REQUIRED FOR GLIDE ANGLE

Power Lever Linkage Failure
If the Power Lever linkage fails in flight, the engine will not respond to
power lever control movements. Use power available and flaps as
required to safely land the airplane.
If the power lever is stuck at or near the full power position, proceed to
a suitable airfield. Fly a forced landing pattern. With landing assured,
shut down engine by moving mixture control full aft to CUTOFF. If
power is needed again, return mixture control to full RICH and regain
safe pattern parameters or go-around. If airspeed cannot be
controlled, shut engine down and perform the Forced Landing
checklist. After landing, bring the airplane to a stop and complete the
Emergency Engine Shutdown on Ground checklist.
If the power lever is stuck at or near the idle position and straight and
level flight cannot be maintained, establish glide and perform the
Forced Landing checklist.
1. Power Lever Movement......................................................VERIFY
2. Power ............................................................................ SET if able
3. Flaps ........................................................................SET if needed
4. Mixture ..................................... AS REQUIRED (full rich to cut-off)
5. Land as soon as possible.
