(984 liters) nor more than 20 fluid ounces per 105 gallons (397 liters) of
fuel. Use not less than 20 fluid ounces (1 can) of MIL-I-85470 per 155
gallons (587 liters) nor more than 20 fluid ounces per 105 gallons (397
liters) of fuel.
Refer to Addendum I — FUEL SERVICING for additional information.
On aircraft 45-065 & subsequent and prior aircraft modified by SB 45-11-1:
Anti-icing additive is not a requirement. However, for microbial protection,
it is recommended that fuel containing either an approved biocide
additive or an anti-icing additive conforming to MIL-I-27686 be used at
least once a week for aircraft in regular use and whenever a fueled aircraft
will be out of service for a week or more.
Refer to Addendum I — FUEL SERVICING for additional information.
BIOCIDE ADDITIVE
Biobor JF is approved for use as a biocide additive when premixed with
fuel in the fuel supply facility. Blending of Biobor JF and fuel using the
gravity fill method of refueling is not approved. Additive concentration
is not to exceed 270 ppm. Refer to Addendum I — FUEL SERVICING
for additional information.
FUELING
On aircraft 45-002 thru 45-156 not modified by SB 45-28-2, Single-point
pressure refueling is limited to 40 psig (2758 hPa) and defueling is
limited to -10 psig (-690 hPa).
On aircraft 45-157 & subsequent and prior aircraft modified by SB 45-28-2,
Single-point pressure refueling is limited to 55 psig (3792 hPa) and defueling
is limited to -10 psig (-690 hPa).
HYDRAULIC FLUID LIMITS
APPROVED HYDRAULIC FLUIDS
Hydraulic fluids conforming to military specification MIL-H-5606 are
approved.

AUXILIARY POWER UNIT (APU) LIMITS
The APU is limited to ground operations only, up to field pressure altitudes
of 10,000 feet, and must be shut down prior to takeoff.
Operation of the APU during gravity fill refueling is prohibited.
Operation of the APU during fluid de-icing/anti-icing is prohibited.
Do not takeoff with an APU FAIL amber CAS illuminated. In the event
the APU automatically shuts down due to an APU failure, a visual inspection
of the unit must be conducted prior to flight.
APU STARTER LIMITS
APU GENERATOR LIMITS
- Continuous — 300 amps.
If more electrical load is applied than can be supplied
by the APU generator, the current will be
drawn from the aircraft batteries and will not be
shown on the DC amps display. If this occurs, DC
voltage will be reduced.
- Transient — Higher transient loads for cross-starts and battery
charging are authorized.
APPROVED FUELS
Fuels approved for the main aircraft engines are also approved for the
APU.
APPROVED OILS
Refer to Addendum II — ENGINE OIL SERVICING for a listing of
approved oils.
