SERVICING
Who is authorized to perform servicing and handling of aircraft?
All PQMs and aircrewmen qualified in model when qualified maintenance personnel are not available
3.1.1 [Note]
SERVICING
When refueling, A minimum of _____ feet should be maintained from other aircraft or structures and _____ feet should be maintained from any operating radar set.
50, 75
3.1.2
SERVICING
If JET B is used, the following operational restrictions/considerations apply:
“HOS-Refuel” [pronounced like Hose]
- All takeoffs shall stabilize in a hover with no fuel pressure cautions for a minimum of 10 seconds before transitioning to forward flight.
- Lower operating temperatures, slower accelerations, and shorter range may be experienced.
- Single-engine training is prohibited.
- Due to the vapor qualities of JET B, the next two refuelings with a primary fuel shall be treated as if JET B is in the tanks.
3.1.2.1
SERVICING
When fueling with JP-5 is not possible, helicopters shall not be hangared until the flashpoint of the fuel in the helicopter fuel tanks is above _______.
120 F
3.1.2.1
Figure 3.1-2: For planning purposes, a fuel mixture of 70% JP-5 and 30% JP-8 or Jet A-1 will ensure the minimum flashpoint of the fuel mixture is above 120F.
SERVICING
Fuel Types and operational Considerations
Flameouts nose down
Flameouts may be encountered following nose down ground operations in excess of 10 minutes when using JP-5, JP-8, or equivalent fuels.
3.1.2.1 [Warning]
SERVICING
(V) Definition: Primary Fuel
A fuel that the aircraft is authorized to use for continuous unrestricted operations.
3.1.2.1
SERVICING
(V) Definition: Restricted Fuel
A fuel that imposes operational restrictions on the aircraft.
3.1.2.1
SERVICING
What is the maximum fueling pressure
To prevent possible fuel cell rupture, fueling pressure from the fueling service unit shal not seceed 55 psi.
3.1.2.3 [Warning]
SERVICING
Maximum fuel cell pressure
Internal fuel cell pressure greater than 2 psi can cause rapid fuel cell expansion, resulting in aircraft damage and fuel spill.

SERVICING
Precheck valve fails to secure flow
As long as one precheck valve is operative, the aircraft can be refueled safely.
If neither precheck valve will secure fuel flow fueling should be continued only if necessary.
3.1.2.3
SERVICING
When operating with fuel that does not contain FSII, bulk fuel temperature shall be maintained above ______.
What are the steps to do so?
0 deg C.
- If the aircraft has been in heated hangar, launch within 1 hour of being moved to the flight deck or turnup area.
- If outside for more than an hour, drain the fuel into a bottle that has been outside 15 minutes to check bulk temperature.
- If fuel is 0C or less hangar the aircraft until fuel is above 0 or partially defuel and add warm fuel.
