9-13. LOSS OF PRESSURIZATION (ABOVE 10,
If cabin pressurization is lost when operating
above 10,000 feet or the ALT WARN warning
annunciator light illuminates, perform the following:
Crew oxygen masks - 100% and on.
9-14. CABIN DOOR CAUTION LIGHT ILLUMI-
Remain clear of cabin door and perform the fol-
Bleed air valve switches - ENVIRO OFF.
Descend below 14,000 feet as soon as practi-
3. Oxygen - As required.
9-15. SINGLE-ENGINE DESCENT/ARRIVAL.
Approximately 85% N1 is required to
maintain pressurization schedule.
Perform the following procedure prior to the
final descent for landing.
Cabin controller - Set.
Ice and rain switches - As required.
3. Altimeters - Set.
Recognition lights - ON.
Arrival briefing - Complete.
9-16. SINGLE-ENGINE BEFORE LANDING.
Propeller lever - As required.
During approach, propeller should be set
at 1900 RPM to prevent glideslope inter-
ference (ILS approach), provide better
power response during approach, and to
minimize attitude change when advancing
propeller levers for landing.
2. Flaps - APPROACH.
3. Gear - DN.
Landing lights - As required.
5. Yaw damp - OFF.
6. Brake deice - OFF.
9-17. SINGLE-ENGINE LANDING CHECK.
Perform the following procedure during final
approach to runway.
Autopilot/yaw damp - Disengaged.
Gear lights - Check (three green).
3. Propeller lever (operative engine) - HIGH
To insure constant reversing characteris-
tics, the propeller control must be in the
HIGH RPM position.
9-18. SINGLE-ENGINE GO-AROUND.
The decision to go around must be made as
early as possible. Elevator forces at the start of a go-
around are very high and a considerable amount of
rudder control will also be required at low airspeeds.
Retrim as required. If rudder application is insuffi-
cient, or applied too slowly, directional control can-
not be maintained. If control difficulties are experi-
enced, reduce power on the operating engine
immediately. Insure that the aircraft does not touch
the ground before retracting the landing gear.
Retract the flaps only as safe airspeed permits
(TAKEOFF until V ref, then UP).
engine go-around as follows:
Once flaps are fully extended, a single-
engine go-around may not be possible
when close to the ground under condi-
tions of high gross weights and/or high
Power - Maximum allowable.
2. Gear - UP.
Flaps - As required.
4. Landing lights - OFF.
5. Power - As required.
Yaw damp - As required.
