Section 1: BATT Introduction
Overview
This manual covers the assembly, installation, operation and maintenance of SEI's Bulk Aviation Transport
Tank (BATT).
The BATT is approved for use in Canada under SEI Industries Ltd.'s Transportation of Dangerous Goods
Equivalency Certificate (SU 10638) from Transport Canada allowing the BATT to be used without special
permits for the transportation of jet or diesel fuels (a separate gasoline model is also available).
The BATT is limited to supplying fuel to areas with remote access or where other transportation options are
not readily available or practical. It shall be used for fuel transportation purposes only and is not intended
for long term fuel storage. The certificate also states that the fuel must be loaded into a flexible tank that
meets all the specifications of the BATT as manufactured by SEI Industries Ltd.
Warning
This manual covers BATT models that are only designed for use with diesel or Jet A fuel. There
is a separate model for use with gasoline.
Warning
The BATT is designed for the transportation of dangerous goods and its design is for limited access
operations only. No passengers are allowed during bulk fuel transport operations.
Warning
The BATT’s operational temperature range is from -46C to +50C on condition that transported fuel
temperature deviance during one operational cycle does not exceed 50C.
Caution
A copy of SEI Industries Ltd.'s Transport of Dangerous Goods Certificate (SA 10638) must remain
with the tank at all times during use.

Section 1: BATT Introduction Overview
2019 BATT Diesel/Jet Fuel Operations Manual (Version K) 2
We Engineer Solutions
Tank Construction
The BATT is a pillow-shaped, collapsible, double-walled fabric container equipped with a number of
internal liquid stabilizing elements (baffles), an external built-in harness as well as fill, drain and vent
fittings and lifting handles.
Structurally, the BATT consists of outer and inner bladders. The outer bladder provides secondary
containment and protection for the inner bladder from abrasion. It has a built-in strapping system that
enables the BATT to ensure a secure fit onto an aircraft cargo deck at various filled capacities. Each
adjustable strap includes a tensioning device (ratchet buckle) and snap-hooks. The straps are connected to
the tank through steel-forged D-rings and special fabric mounting points on the outer tank. Straps can easily
be replaced in case of damage. The outer tank has a leak-proof, fuel-resistant liquid-tight zipper that can be
opened to allow inspection of the inner tank for leaks or damage.
The inner bladder provides containment for transported fuel. It has built-in liquid stabilizing and bladder
restraining elements with wall-like structures (baffles) to reduce fluid surge. Inner and outer bladders are
interconnected by built-in handles aligned face-to-face, between the inner and outer bladders and the outside
lifting handles, and by NPT threaded flanges which clamp inner and outer bladders.
The BATT is rated to its maximum volume. The BATT bladder and harness rating is based on sg = 0.85 of
the transported liquid. If the specific gravity of the liquid you are transporting is heavier, you must decrease
the capacity of your tank.
Each BATT has its own serial number (punched on top of the NPT threaded flanges) and is marked with its
authorized fuel type, wet date, fill height, maximum capacity and dry weight.
For BATT model general parameters, please see Section 8 of this manual.

Fittings
The BATT has one or more vent ports. During flight, the vent is closed unless it is connected to an external
vent system (if one is installed in the aircraft already). If the vent is connected to an external vent system,
ensure that the vent is secured and that it vents outside of the cargo area. The vent is only closed during
flight and must be open on the ground.
The tank also has one or more fill/discharge ports. All these fittings come with valves and quick
connections. Dust plugs or caps are tethered to the tank to keep dust or dirt out of the fittings.
Conditions of Use
It is the operator's responsibility to ensure the BATT is approved for use by the authority having jurisdiction.
In Canada, the BATT is approved under the SEI Industries Ltd. Equivalency Certificate SU 10638. It is
important that operators review this certificate and keep a paper or electronic copy. Equivalency Certificate
SU 10638 and the BATT operations manual shall accompany all dangerous goods. Since this equivalency
certificate has been updated numerous times, it is the air operator's responsibility to ensure that the most
recent version accompanies the dangerous goods. You can download the latest version of the BATT
Equivalency Certificate SU 10638 by visiting our website at http://www.sei-ind.com/products/bulk-
aviation-transport-tank.
Operators need to ensure that the personnel handling and transporting the dangerous goods in the BATT are
trained in regards to the conditions of Equivalency Certificate SU 10638. This training must be documented.
SEI also recommends keeping a copy of the current revision of the BATT-Spec with the BATT Equivalency
Certificate SU 10638 for reference. If you do not have a copy, you may request one by contacting SEI
Industries at [email protected] or by calling 1-604-946-3131. SEI regularly sends updates to operators who
have purchased the BATT. To maintain compliance, please make sure your latest contact details are on file
with us.
Warning
It is the operator’s responsibility to ensure that the tank capacity does not exceed the aircraft’s
gross load capabilities for specific mission profiles.
Warning
Tanks must be taken out of service five years after the manufacturing date and returned to the
manufacturer for testing. See Section 7 for more information.

Section 2: BATT Fittings
Installation of Fittings
Description of Fittings
BATT fittings include:
• Fill/discharge fitting, at least one per tank
• Vent fitting, at least one per tank
Each fitting consists of two main parts: a part attached to the tank using an NPT connection and a removable
part attached to the first part using a quick connection. The vent fitting is complemented by a detachable
vent hose. It is recommended to have a vent hose installed and a hose end directed outside the fuselage
during tank venting in order to avoid contamination of the fuselage’s inner space with fuel splashes and
vapor. BATT fittings are supplied as pre-assembled units and don't require any additional assembly before
installation on the tank.
Thread Sealants
Thread sealant must be used during the installation of threaded fitting parts into BATT flanges.
Recommended thread sealants include:
• Loctite 567 or Loctite 565 paste threads sealant or equivalent. These sealants are pref-
erable. They can be applied in ambient temperature + 10 C or higher.
• Loctite 55 pipe sealing cord
Important Note
For aircraft fitted with tail dragger landing gear, the vent should be installed in the flange closest
to the cockpit. For aircraft fitted with tricycle landing gear, the vent should be installed in the
flange at the center of the tank.
Warning
Do not allow the pipe fitting to cross thread into the flange as this will damage the flange thread.
This flange cannot be replaced in the field.

Fitting Installation Using Loctite 567 or Loctite 565 Thread Sealant
1. Disengage fitting parts.
2. Remove protective plug from the BATT flange and protective cap from the fitting threaded part.
3. Clean thread surfaces (external and internal) with a cleaning solvent (e.g. Loctite) and allow to
dry.
4. Spray thread surfaces (external and internal) with Loctite 7649 primer and allow to dry;
5. Apply a 360 degree bead of thread sealant to the leading threads of fitting part, leaving the first
thread free.
6. Force the sealant into the threads to thoroughly fill the voids.
7. Install fitting threaded part into the BATT flange. As a general rule for 1", 1.5" and 2" threads,
hand tighten the fitting part and then tighten three more full turns with a wrench. For 3" threads,
hand tighten the fitting part and then tighten two more full turns with a wrench.
8. Allow the sealant to cure a minimum of 24 hrs.
9. Engage BATT fitting.
Fitting Installation Using Loctite 55 Thread Sealant
1. Disengage fitting parts.
2. Remove protective plug from the BATT flange and protective cap from the fitting threaded part.
3. Clean thread surfaces (external and internal) with a wire brush prior to application of the sealant.
4. Hold the end of the pipe sealing cord against the male nipple with one finger, approximately two
threads away from the end.
5. Wind the fiber onto the pipe threads away from the end of the pipe. The grooves of the threads
should be filled without completely masking the pitches or the thread (it is not necessary to follow
the valley of the thread).
Important Note
Threaded connections can be disassembled with standard hand tools. Cured sealant can be re-
moved with a combination of soaking in a Loctite solvent (or equivalent) and mechanical abrasion
such as with a wire brush.

Section 2: BATT Fittings Installation of Fittings
2019 BATT Diesel/Jet Fuel Operations Manual (Version K) 6
We Engineer Solutions
The following is a guideline for how much Loctite 55 to use per thread size:
6. Cut the required length off and smooth the loose end onto the pitches of the pipe thread.
7. Engage BATT fitting.
Caution
Do not over apply the pipe sealing cord. Excessive material tends to be pushed off as the thread
connection is assembled and it also becomes mechanically more difficult to complete the
engagement.
Thread Size Number of Turns (wraps)
1” 8 to 12
1-1/2” 10 to 15
2” 15 to 25
3” 25 to 35
Important Note
Loctite 55 can be adjusted up to 90 degrees after tightening.

Section 3: General Safety
Safety Procedures
Common Safety Rules
The handling of petroleum fuels is a potentially dangerous operation. The following rules should always be
observed:
• Keep fueling site free of debris and flammable material.
• Observe all normal safety practices such as a strict “no smoking” rule.
• Collect all intentional spillage in a container and discard safely.
• Keep all unnecessary personnel off site.
• Use grounding and bonding devices where applicable.
• Have a fire extinguisher staffed during refuelling and defuelling.
• Do not pack and ship containers with fuel residue inside.
• Keep fitting connections locked.
• Fill/drain valve(s) must be closed and locked except during fueling and defueling opera-
tions.
• Vent valve(s) must be closed and locked except during fueling operation.
• Before and during fueling and discharging operations, the BATT, the aircraft, tanker
truck, pumps, hoses, loading facility and operator must be bonded.

Section 4: BATT Operation
Installation and Operations
Tank Positioning
Before the BATT’s first installation, make sure that the wet date is recorded on the BATT label and in the
BATT Semi-Annual Inspection Log which is included in the BATT operations manual (BATT service life
starts from the wet date or 12 months from the date of manufacture, whichever comes first).
1. Before starting the installation, make
sure the cargo area is clean and any
sharp objects smoothed (if part of the
aircraft) or removed, if they are not
attached.
2. SEI recommends that a chafing liner be
used in the aircraft. This liner can be a
canvas sheet or any other low-cost
liner material. This liner is used to pro-
tect the outer tank from any sharp
objects found on the deck of the air-
craft.
3. Once the liner is installed, it should
look as shown. Make sure to keep the
attachment points exposed by folding
the liner back on the sides, front and
back.
Important Note
Follows the conditions of the Equivalency Certificate (SU 10638)
Low-cost chafing liner installed prior to BATT.
Warning
The BATT is designed for the transportation of dangerous goods and its design is for limited access
operations only. No passengers are allowed during bulk fuel transport operations.

4. Unroll and position the tank, making sure the fill end is in
the correct location and the tank is properly positioned to
maintain its center of gravity. Use BATT handles to adjust
the tank’s position.
5. Secure the tank to the tie down points and adjust the straps
so they are loose. Tie-downs shall be evenly distributed
lengthwise. The tie-down arrangement shall be symmetri-
cal on each side of the tank. For minimum distances
between any two attachment points, refer to the aircraft cargo loading manual.
Chain Links
Prevention of Static Electricity Build-Up
Before making any fueling connections to the BATT, the BATT fill/drain fitting shall be bonded to the
aircraft by use of a cable and the fueling equipment shall be bonded to the aircraft, providing a conductive
path to equalize the electrical potential between the fueling equipment, aircraft and BATT. The bond shall
be maintained until fueling connections have been removed.
As clothing and footwear are major cause of static electricity build-up, personal involved in BATT refueling
operations should minimize the amount of friction/rubbing on the tank and lining surfaces. It is
recommended to wear anti-static clothing and footwear for personal involved in BATT operation. Using
garments made of synthetic materials should be avoided. The person who operates the BATT has to be
discharged by touching an aircraft metal part before touching any BATT fittings. Failure to fully discharge
may ignite fuel vapours.
Operators need to ensure that the chain links are installed across the zipper before filling
the tank. When the chain links are removed for inspection, they must be replaced. If they
are not installed before filling, then it is possible to damage the zipper. If the zipper is
damaged, the tank will need to be returned to SEI for repair. It cannot be field repaired.

Section 4: BATT Operation Installation and Operations

Fueling Procedure
1. Perform BATT daily inspection (see Section 5).
2. Connect the BATT fill/drain fitting bonding cable to the airframe’s exposed metal surface.
3. Attach hose to fill/drain fitting. Open fill and vent valves.
4. Start pumping. Monitor the volume being pumped into the tank to prevent the tank from being
overfilled. Harness straps should remain loose during tank filling.
5. After filling tank, close the fill valve and keep the vent valve open for 1-5 minutes to let air
escape. Then, close the vent.
6. Close the valve and leave it closed during flight.
7. Enter filling information into a tank logbook (provided by operator).
Restraining the Tank
Tighten the straps to secure the tank. With ratchet
tensioning devices, there should be a minimum of two
full webbing wraps around the spool once the strap is
fully tensioned.
All straps should not be twisted and should be equally
tensioned, without any slack but also without any excess.
Warning
All BATT models are rated to contain liquid with a specific gravity sg = 0.85. If the specific
gravity of the liquid you are transporting is heavier, you must decrease the capacity of your tank.
Caution
Check the label on the tank for capacity. The tank shall be filled to at least 70% of its rated
capacity. Never fill the tank over the rated capacity.

Section 4: BATT Operation Installation and Operations
2019 BATT Diesel/Jet Fuel Operations Manual (Version K) 11
We Engineer Solutions
Defueling Procedure
1. Attach hoses to the fill/drain fitting.
2. Open all valves on the discharging fuel line.
3. Start pumping into the tank accepting the fuel load from the BATT.
4. Slow down the pumping as you near the end of defueling. Manually position the fill/drain fitting
to minimize the amount of fuel left in the tank.
5. Once the discharging fuel is finished, confirmed by an empty/flat BATT tank, close all valves
starting at the BATT tank and finishing at the accepting tank.
6. Disconnect all hoses and cap them over a drip tray or, if unable due to being on top of the tank, an
absorbent pad.
7. Disconnect the BATT fill/drain fitting bonding cable from the airframe.
Transporting the Empty BATT
In a repetitive use environment, the BATT may be transported in a folded or unfolded state. In both cases,
the tank should be emptied to the maximum extent possible. All fittings should be closed and the BATT
should be secured to the airframe.
If the BATT will likely be folded, protection for the fill/drain fittings should be carried to prevent damage
to the bladder.

Section 5: Maintenance and Repair Inspections
2019 BATT Diesel/Jet Fuel Operations Manual (Version K) 12
We Engineer Solutions
Section 5: Maintenance and Repair
Inspections
The actual service life of a BATT will depend on the completeness and quality of meeting operational and
maintenance requirements.
Daily Inspection
Visual inspections of the outside surface of the tank shell, tank harness, vent fittings and fill/drain fittings
should be conducted on a daily basis or performed every time a BATT tank is used.
1. Inspect the outer tank shell for signs of wear and tear, damages, leaks and excessive surface con-
tamination. If contamination is found, the tank should be cleaned with mild soap and water. Con-
tamination with spilled fuel must be cleaned as soon as possible. If repairs are required, see
Repairs in this manual.
2. Inspect the tank harness for signs of wear and tear, damages and contamination. Special attention
should be paid to the sewing on stitches and the serviceability of strap fittings. Webbing straps
that have been contaminated with a substance (e.g. oil, grease, fuel etc.) that could affect success-
ful tensioning should be replaced. Damaged straps must be replaced.
Warning
Never remove the flanges to extract the inner tank from the outer tank. This can only be done at
an authorized SEI service centre.

Section 5: Maintenance and Repair Inspections
2019 BATT Diesel/Jet Fuel Operations Manual (Version K) 13
We Engineer Solutions
Semi-Annual Inspection
The semi-annual inspection should be performed six months (+/- two weeks) from the tank’s wet date or 12
months from the manufacturing date, whichever comes first. The semi-annual inspection includes a visual
inspection of the inner bladder condition.
1. Open the outer tank zipper. Inspect the space between the inner and outer tanks (within reasonable
reach) for signs of leakage. Also, inspect the inner and outer bladder fabric condition. Special
attention should be paid to the area closest to the handles and around the flanges. Do not disas-
semble flanges or disengage handles.
2. Before closing the zipper, lubricate both halves of the zipper with zipper lubricant. Close the zip-
per slowly to the end, making sure that all zipper teeth are engaged. Wipe away any excessive
lubricant.
3. When the tank is filled for the first time after an inspection, open the zipper ¼" to ½" just to create
enough opening for air to escape. After filling tank and releasing the air from the space between
the inner and outer bladders, close the zipper to the end.
4. Fill in the Semi-Annual Inspection Log which is provided in the back of this manual.
Important Note
If a leak is discovered, the BATT must be drained completely and sent to SEI Industries for
possible repair and re-testing.

Repairs
Emergency/Temporary Repairs (BATT Assembly)
For emergency/temporary repairs, use the BATT emergency repair kit (attached to the tank). Temporary
repairs can be performed only in emergency situations in order to reduce or eliminate fuel leakage caused
by holes or cuts in the tank shell. Any BATT subjected to a temporary repair must be drained as soon as
possible. After draining, the tank shall be sent to SEI Industries for evaluation and possible repair.
Small Holes (rips, cuts or holes up to 1")
Use wooden screws to plug small holes:
• If the hole is too small to insert a wooden screw,
widen it up to ½" using a knife or other sharp
object. The wooden screw method is best used
on "round-shaped" holes. If the tear is slit-
shaped, then use a knife to make the opening
more round.
• Insert the plug into the hole and turn it clockwise
until tight.
Large Holes (rips, cuts or holes up to 6")
Use sealing clamps to patch larger holes:
1. Select the largest clamp that will just slip through the hole. The size of cut or hole will determine
the size of the sealing clamp to use. Use scissors if the hole requires adjustment.
• For a cut or hole up to 2" (5 cm), use a 3" (7.6 cm) clamp.
• For a cut or hole up to 4" (10 cm), use a 5" (12.7 cm) clamp.
• For a cut or hole up to 6" (15 cm), use a 7.5" (19 cm) clamp.
Wooden screws can be used to make
temporary repairs.

2. Keeping hold of the string, slip one half of the repair clamp
through the hole.
3. Pull the bolt up through the hole. Turn it until the clamp
lines up with the hole.
4. Place the top of the clamp over the bolt.
5. Tighten the nut by hand.

Section 5: Maintenance and Repair Repairs
2019 BATT Diesel/Jet Fuel Operations Manual (Version K) 16
We Engineer Solutions
Permanent Repair (Outer Bladder Only)
For outer tank minor permanent repairs, use the BATT patching kit (not attached to the tank). Small local
damages on the outer bladder can be repaired using a special adhesive. SEI recommends Aquaseal urethane
repair adhesive and Cotol-240 surface cleaner and cure accelerator for outer bladder permanent repair.
Pinholes, Small Scratches and Tears
1. Clean the damaged area and ¼" beyond it with an abrasive pad and Cotol-240 (or isopropyl alco-
hol).
2. Create backing with wax paper or masking tape if needed (to prevent the glue leaking through and
sticking to the inner bladder).
3. Paint the damaged area and ¼" beyond edge with Aquaseal or Aquaseal mix. Aquaseal will cure
to full strength in 8 to 12 hours. To speed cure time to 2 hours, pre-mix one part Cotol-240 with
two or three parts Aquaseal before applying. Additional Cotol-240 can be added to thin Aquaseal
to desired viscosity.
4. If the defect is not sufficiently fixed, a patch repair may need to be applied.
Cuts and Holes up to 1"
1. Cut a patch. The patch should be at least 2" larger in every direction from the damaged area. A
round patch is recommended but, if a rectangular patch covers the damage better, then round all
corners.
2. Draw an outline of the patch on the surface to be patched.
3. Trim loose threads and loose coating on damaged area with scissors to a point where there is a
solid bond between the reinforcing fabric or scrim and the coating.
Important Note
If the size of the damaged area exceeds 1", please contact SEI Industries before making repairs.
Warning
Use of adhesive and accelerant can be dangerous and can have short term and long term
consequences for human health. It is important to take precautions and wear all appropriate safety
gear. Wearing gloves, a respirator, eye protection and working in a well-ventilated area can help
to mitigate these risks.
