S/Ns 30576, 30687, 30931, 30817
and 30599 use an AC Fuel
Pressure indicating system. See
section 96.5 for details. For all
S/Ns except 30576, 30687, 30931,
30817 and 30599 refer to this
section for details of the DC Fuel
Pressure indicating system.
96.6.28.1
The fuel pressure indicator system
is a remote type indicating system. DC power is
routed through a circuit breaker to the
transmission oil pressure indicator which supplies
an excitation voltage to the transmitter. Any
pressure sensed by the transmitter will be
indicated on the fuel pressure indicator.
96.6.29 Operational Check – DC Fuel
Pressure Indicator
SPECIAL TEST EQUIPMENT
TYPE OR MODEL NOMENCLATURE
Barfield Type Pressure Tester 0 –
2311F-S or Equivalent 150 psi (0 – 1034 KPa)
96.6.29.1 Perform
operational check as
follows:
96.6.29.1.1
Disconnect fuel pressure line from
fuel pressure transmitter on engine.
96.6.29.1.2
Attach dead weight pressure
tester to the transmitter and apply 50 psig (344.8
KPa) to transmitter. Do not exceed 57 psig (393.0
KPa)
96.6.29.1.3
Apply electrical power to the
helicopter electrical system. Verify ENGINE FUEL
pressure indicator reads 50

7 psi.
96.6.29.1.4
Turn electrical power off.
96.6.29.1.5
Reduce pressure and remove
pressure tester from pressure transmitter.
Connect fuel pressure line to fuel pressure
transmitter.
96.6.30 DC Dual Tachometer Indicator
NOTE
S/Ns 30576, 30687, 30931, 30817
and 30599 use an AC Dual
Tachometer indicating system.
See section 96.5 for details. For
all S/Ns except 30576, 30687,
30931, 30817 and 30599 refer to
this section for details of the DC
Dual Tachometer indicating
system.
96.6.30.1
The DC dual tachometer indicator
system consists of the engine power turbine
tachometer generator, rotor tachometer generator
and dual tachometer indicator. The DC dual
tachometer indicator uses DC power for internal
regulation.
96.6.31 Operational Check – DC Dual
Tachometer Indicator
SPECIAL TEST EQUIPMENT
TYPE OR MODEL NOMENCLATURE
Howell H337 Engine test set
or Equivalent
96.6.31.1 Perform
operational check as
follows:
96.6.31.1.1 Apply electrical power to
helicopter electrical system.
96.6.31.1.2 Disconnect
connector (P35) from
main rotor tachometer generator and connect to
matching receptacle on test set.
96.6.31.1.3
Energize tachometer generator on
test set.
96.6.31.1.4 Verify
rotor tachometer pointers
on pilot and copilot dual tachometers read upscale
and indicate speed at which test set tachometer
generator is turning.
96.6.31.1.5 Disconnect
connector (P35) from
test set and reconnect to rotor tachometer
generator.
96.6.31.1.6 Disconnect
connector (P111) from
engine power turbine tachometer generator and
connect to matching receptacle on test set.
