1. the fuel is a known grade (80/87 or 100/130),
2. it is properly filtered before reissue.
Disposition of Suspect Fuel
Removed From Aircraft
Fuel removed from any aircraft that has recently
experienced engine or airframe fuel system problems
possibly related to fuel quality must be segregated by
collecting in a designated defueler, a clean storage
tank, or any container as salvage fuel. It must then
be sampled and tested to determine if it is in confor-
mance with the deterioration use limits. If the fuel
tests within the established limits, it can be returned
to station storage and reissued as the grade and type
determined providing adequate filtration and water
separation can be accomplished prior to dispensing
Aviation turbine fuels that do not meet the re-
quirement specified previously generally cannot be
downgraded for any aircraft use. Questions concern-
ing the use or disposition of fuel not meeting the
deterioration use limits should be referred to the Na-
val Petroleum Office.
Barge or tanker receipt of product requires plan-
ning. The Fuel Maintenance Officer must post written
orders designating the following:
Pier preparation and inspection
Pipelines to be used
Number and sizes of hoses to be connected
Tanks into which cargo is to be received
Pumphouses and pumps to be operated
Number of samples and location where sam-
ples are to be taken
Communications to be used
Preparation of the Declaration of Inspection
(an Environmental Protection Agency require-
ment in the 33 Code of Federal Regulations
administered by the Coast Guard).
The activity instruction covers standard operating
procedures for the following:
Filling of lines before the barge is docked
Notification to start unloading
Line patrol and gage check
Change in pump operation
Barge stripping procedure and stripping speed
Final inspection of barge tanks
Draining pier lines
Personnel manning level
Personnel training requirements
Special clothing requirements
Fuel sampling and testing requirements
Pipeline receipt of product requires essentially the
same planning as barge receipt, and a written order is
required. Some pipeline operations, however, are rela-
tively simple and, therefore, require minimum person-
Incoming tank trucks and tank cars of aircraft fuel
might arrive separately or in groups. All must be sealed
at the source of supply. Unloading of tank trucks re-
quires approximate y 1/2 hour and is a two-man opera-
tion. Tank cars are usually left on a siding or in place
for the offloading operation. The following procedures
apply to both tank truck and tank car receipt:
1. Ensure that the seals are intact.
2. Verify that seal numbers are identical to those
on the shipping document.
3. Verify the specification and grade number of
the product on the shipping document.
4. Make sure the fuel level coincides with the
marking on the tank and the quantity on the shipping
5. Take a bottom sample from each compartment,
first drawing off water if present.
6. Make a visual inspection of samples.
7. Unload the product into a segregated storage
8. Check the vehicles tank interior after delivery.
9. Upon completion of fuel receipt (multiple tank
car or truck loads), sample the storage tank and perform
quality control tests.
