NOTE:
The use of Wide Cut fuel, as agreed by the Operator,
Rolls-Royce and the appropriate Airworthiness
Authority, may result in a reduction in HP Fuel Pump
life.
4. Fuel Additives:
The following fuel additives (in addition to those included in DEF STAN
Specifications) are approved by Rolls-Royce, subject to limitations stated:
A. Corrosion Inhibitor / Lubricity Aids:
Additive:
Concentration Range - Lb
42,035 Gallons (US) / 35,000 Gallons (IMP)
Minimum: Maximum:
HITEC 515 4 (11 mg/l) 7.5 (21 mg/l)
APOLLO PRI 19 3 (9 mg/l) 8 (23 mg/l)
TOLAD 245 7.5 (21 mg/l) 12 (34 mg/l)
DUPONT DCI-4A 3 (9 mg/l) 8 (23 mg/l)
HITEC 580 3 (9 mg/l) 8 (23 mg/l)
NOTE:
Minimum requirement is to ensure that sufficient
additive is available when it is required to act as a
lubricity aid.
B. Anti-Icing Additive:
• DEF STAN 68-252 or:
• MIL-I-27686E or:
• Any direct equivalent in concentrations not exceeding 0.15 percent
by volume

C. Static Dissipater Additive:
• Shell A.S.A. 3 in concentrations of not more than 1.00 parts per
million
• Stadis 450 maximum concentration not more than 3.00 parts per
million
D. Anti-Microbiological Additive:
(1) Methyl Cellosolve:
Methyl cellosolve may be used. Refer to GIV Maintenance Manual
for additive application procedures.
(2) Biobor JF:
Biobor JF may be used. Refer to GIV Maintenance Manual for
additive application procedures.
(3) Kathon FP 1.5:
Kathon FP 1.5 may be used. Refer to GIV Maintenance Manual for
additive application procedures.
NOTE:
Under certain conditions, solid matter may be
precipitated from fuel containing Biobor JF or Kathon
FP 1.5 during flight. The fuel differential pressure
signals should be carefully monitored in flight
immediately following its use in the airplane tanks.
Refer to Rolls-Royce Tay Maintenance M-TAY-1RR for
recommended procedures to be followed when using
Biobor JF or Kathon FP 1.5.

2A-28-20: Fuel Storage System
1. General Description:
The fuel storage system contains all the necessary fuel for the aircraft engines
and the Auxiliary Power Unit (APU). It is composed of the following subsystems,
units and components:
• Wing Fuel Tanks
• Fuel Hoppers
• Gravity Water / Fuel Drain System
• Fuel Ventilation System
• Over-Wing (Gravity) Fueling System
2. Description of Subsystems, Units and Components:
A. Wing Fuel Tanks:
The integral wing tanks include most of the internal wing structure between
the forward and rear spars. The centerline fuselage rib at Buttock Line Zero
(BL0) and a sealed rib at Rib Body Station (RBS) 433 form the inboard and
outboard edges of each wing tank, while the wing planks form the upper
and lower confines.
The external underside of the centerline rib is protected by a non-sparking
skeg panel that serves to protect the underside of the aircraft in the event
of a gear-up landing.
Partially sealed sheet metal ribs form part of the wing structure and divide
each wing tank into five compartments. The ribs act as baffles to prevent
