What Do You Do When You Have A QC Problem? Eliminate Any Risks Fix the Problem Educate Your People But everybody will avoid calling the Associated Press, and that is why you rarely hear of problems at other locations, but believe it, there are problems!
What is Our #1 Job? To put the correct clean, dry, unadulterated fuel into the correct aircraft To do the job safely To prevent fire To prevent spills To follow the QC program and make sure others do also To properly operate and maintain the equipment To always be on the lookout for potential problems
Utilize the Latest Equipment Velcon VF-1 Rampmaster .2 Grounding Cable
Truck Internal Valves NFPA 407 Precheck even if Scully is used Make sure emergency shutoff closes valve Do not use truck unless internal valve operates properly
Quality Control is: Having the Correct Equipment Tests and Procedures - To ATA-103,ASTM API and Other Standards A Pain in the Butt Making Sure You Don’t Damage the Aircraft Not a Profit Center An Indispensable Policy That Must Permeate Your Entire Company From The Top to the Bottom Covering Personnel, Environmental and Flight Safety MOST IMPORTANTLY It must be followed!
Make sure the paperwork matches the aircraft? Do You Check Your People to Make Sure The Paperwork System is Being Followed? Worn Equipment Is a Sign Of Use!
LOOKING FOR CHANGES The Key to Quality Control is to take note of anything out of the ordinary. Even if the results are still within “acceptable” limits, a sudden change to any characteristic or the performance of any piece of equipment may indicate a serious problem Testing and Sampling is Meant to Find Little Problems Before They Become Big Ones!
Changes To Look For Any and All Test Results -Even if the Results are “Acceptable” “Too Good” or “Too Consistent” Results (Pencil whipping) Outside of Prefilter Elements Inside of Coalescer Elements Strainers Nozzle - Coffee grounds and metal shreds???? Differential Pressure / Flow Rate White Buckets - All Aspects, color, odor, haze, “lace”, water, etc. Membrane Test Time Paperwork Labor Times for Inspection Employees Equipment Appearance DID YOU MAKE A CHANGE? - Nozzle pressure changes with hose length or size!
True? A check is in the mail I’ll love you in the morning We only use dedicated tractor trailers Our pipeline always makes perfect “cuts” Our equipment never breaks down Our membranes are always A-0 We never see any differential pressure We never have any water in our fuel In 20 years we’ve never had a problem ====up until now===
The Most Overlooked Aspect of Fuel Quality Control Receiving Fuel Oh, you're the picky guys. (Actually said by a terminal employee.) Jet Fuel, Avgas, same thing, right (Actually said by a transport truck driver.) One Rejected Load Was Actually Delivered to the Next Door FBO
Pumping Fuel Into Storage Stick Tank to Make Sure You Have Room Sump any Water From Tank and Filter FIRST Monitor Differential Pressure on Filter Sample the Fuel With MiniMonitor or Millipore Tester Check the Filter Sump after Unloading Check Tank Volume Net Gallons will vary! Record the Data
White Bucket Test Color - Jet Consistent and NOT Pink! Odor Haze / Cloudiness Liquid water in the bottom of the bucket Spill coffee, food coloring or other water based liquid in to be sure the bucket isn’t pure water Particles or Debris Filmy or lace- like floating material Anything else different from the usual Fuel Should be Clear and Bright - No Visible Contamination
CLOUDY FUEL OBSERVED WHILE PERFORMING A WHITE PORCELAIN BUCKET TEST INDICATES ENTRAINED WATER, SURFACTANT OR BOTH
CLEAR WHITE BUCKET SAMPLE INDICATING NO WATER OR PARTICULATES. USE ANY COIN.
A Jar Makes An Inexpensive Test Device For Detecting Haze
Spill In a Little Coffee or Food Coloring And Water is More Distinct
Accurate Hydrometer Readings (Mercury Issue) Spin the hydrometer gently Do not allow it to touch the jar Keep it clean
When You Raise Your View To Be Level With The Surface This Will Indicate API 43.5
Indicated API 40.3 Using A Spill-Over Type Hydrometer Jar
2. Read corrected API at 60 F mark If You Read 43.5 at 81.6 degrees F 3. Result is API gravity at 60 F of 41.65 1. Align measured fuel temperature against measured API
“Normal”Contaminants in Aviation Fuels Dirt Dust (From Tank Vents) Rust Water (Lots of Water!) Surfactants Pieces of Burst Filters Tank Lining Paint Chips Other fuels Microorganisms Rubber from failed hose And MUCH More!
Real Contamination in Aviation Fuels Lavatory “Blue Fluid” Fuel Oil Fertilizer Outlet Prist Can Tubes Lizards Dead Birds Sand Metal Shavings Transmission Fluid Insects Caustic Soda Gloves Rags Eyeglasses Fish Bolts / Other Hardware
Through the Vent or Roof of the Refueler Truck What is the Most Common Way Gross Water Gets into Aircraft?
Keep Rain Drains Clear Any Leak Can Let Rainwater Into The Tank When The Vent Opens Any Standing Water Will Enter the Tank!
The Drain Lines Should Be Transparent Plastic So You Can Inspect For Debris
Water in Aviation Fuels DISSOLVED WATER Like Humidity in Air Cannot be Measured With Field Equipment Cannot be Removed by Filtration 1 PPM per Degree Fahrenheit UNDISSOLVED WATER Free Water Like Fog In Tank Bottoms Slugs Can be Removed By Filtration Will Settle From Fuel Aquarius Additive – 2 to 5 years away Water - Bio - CI/LI – FSII/Prist
1 Gallon Per Million Gallons 1/10,000 of 1 percent What Is A Part Per Million? A Properly Operating Filter Separator or Monitor Will Remove Water Down to NO MORE THAN 5 PPM!
Detecting Free Water In Fuel VISUAL - Haze is Visible at 30 ppm Velcon Hydrokit - Water Detector 15 or 30 ppm Shell Water - Detector 15 or 30 ppm Metrocator - Spotted Paper Indication AquaGlo Water Detector - An Instrument For Measuring Water Water Finding Paste? NO! Only For Water Level In A Tank Bottom Water Probe? Only for detecting water in sumps
As Required by ASTM and API for Measuring Free Water Manufactured Under License From Exxon The Aqua-Glo Water Detector Kit A Free Video On Calibration and Use is Available - Just Call 800-524-0287
MICROBIAL CONTAMINATION FOUND IN THE AIR AS SPORES FOUND MAINLY IN WATER SIDE OF TANK WALL WATER IN TANK BIRD BATHS IT CAN TRAVEL FILTRATION EQUIPMENT AIRCRAFT FUEL TANKS REMEDY/BIOCIDES
Dirt In Aviation Fuel An 87 or 9 Series Coalescer Element Will Remove About 99% of Particles over 1/3 Micron
MiniMonitor Particulate Detector to ASTM D2276 Bonding And Grounding Hose Assembly
Bonding is connecting two parts Grounding is connecting those parts to earth What is Bonding and Grounding? The purpose of bonding and/or grounding is to neutralize sparks between items before and during operations MOST IMPORTANT Bonding aircraft during refueling Bonding and grounding ALL other operations NFPA-407 2001 Actually forbids grounding of refueler trucks in direct refueling
F-15 Hangar Problem Auto-Fire suppression shut off after inadvertent release Explosion during defueling in open air from wing tank They couldn’t be convinced that bonding was necessary They agree now
Ground to Pipe, NOT Fitting as Shown! Our New QD Will NOT Spray Fuel! Flow A Ball Valve Will Aid in Operation In High Pressurized Systems Turn Valve to TEST Position to Flow Fuel Through the Plastic Monitor
Maintain The Bond to the Bucket! Flow 1 or 3 Gallons of Fuel Into the Bucket Ask Your Fuel Supplier or Airline How Much
