Fuel truck

I was tired. Heck, I was tired all the time. It was the early 1980s and the country was coming out of a really deep and protracted recession. I was really glad to now have more flying than I could handle after such a long, dry spell but this unwanted and inevitable side effect of fatigue was with me most of the time.

I was working for my good buddy, Tony Barnum, hauling freight for the Jeep Company in Toledo, Ohio. Tony’s son Eric was in charge of Crow Inc., but Tony kept a hand in the flying part of it. We had a small fleet of Navajos, Aztecs, and Seminoles, left over from the now failing dealership, but they were not the best airplanes for hauling the freight. So we ended up buying three of the “finest Beech 18s in captivity, east of the Mississippi River,” as I used to say.

Usually a BE-18 is a stepping stone for a rookie pilot, and a very demanding one at that. This was not the case for me as I already had about 5000 hours of multi-time in pistons and turbine airplanes. I also had a type rating with over 600 hours of PIC jet time when I left a job flying a Sabreliner and took the job as chief pilot and check airman for Crow Executive Air Charter, so this was a fun thing for me, flying the ole Beech.

We were very busy at the time. Of the five or six pilots we had (I always thought that it was funny to call a guy or gal “captain,” and I still do because I think we should all fly like “captains”), half were rookie pilots that rode the right seat. We called ourselves “the Beech Boys.” We referred to the rookies as the “cast of thousands.” There was much more flying than our small crew could handle so we farmed out a big chunk of the flying we had to other charter operators.

It was my job to break in these new pilots. We had a moderate amount of turnover compared to most Beech operators. I think this was due to the fact that it was a fun place to work and there was no pressure to complete “the mission.” I used to tell them, “If you don’t feel like flying, don’t, no problem.” The equipment was well-maintained. The Beeches had custom paint jobs and were well equipped with decent radios which included good intercoms and even Lorans when they came out. One of them even had a radar in it. I always wondered why all of the big jets I flew for the major airlines didn’t have intercoms, especially when they preach how important communication is. Some airliners had what they called an intercom in them that had to be jerry-rigged to work but, they were a far cry from great units we little airplane drivers have in our planes.

When it came to breaking in new pilots, one of the many things I stressed was that the he or she needed to supervise the fueling of the airplanes. I had heard of a few local crashes involving piston airplanes that had jet fuel put in them. They were usually fatal. I would read about them in the magazines. Bob Hoover was selling a system to prevent it. I even had an up close and personal experience with one very close call.

Several years earlier when I was working line service, Tony flew back into Toledo in the Grumman Mallard to top off with fuel before proceeding to his destination. He had picked up a group of businessmen someplace else and was heading to a fishing camp up north with them.

He had radioed ahead to set up a quick turn and I was standing by with the 100 octane truck running and the hose uncoiled. Tony taxied straight up, shut down, and then crawled out the nose hatch and on to the top of the fuselage to get on the catwalk to the fuel caps on the wings. I was on the ladder and handed him the hose so he could fuel the airplane himself. We filled both wings and off he went.

Fuel truck

Remember to read the truck – Jet A or Avgas?

As I was walking around the back of the line shack, I saw the Mallard taking off and it was about twenty feet in the air when both engines started cutting in and out. Thinking fast, Tony got the wheels back down, which is no small feat in a Mallard. He had to help the engine driven hydraulic pump by using the manual hand pump located behind the copilot’s seat. He was really busy but, with great skill and ability, kept the Mallard from going off the end of the 7000 foot runway. He was even able to keep the motors running long enough to taxi back to the FBO, all the while belching smoke and with wheel grease afire due to the hot brakes. A tremendous feat of pilot skill.

We unloaded the fishermen and dropped them off at the terminal lounge while we tried to figure out what happened. We took off the fuel caps and smelled the fuel but couldn’t tell anything from that. We drained some fuel out and looked at it but still couldn’t detect any jet fuel. It wasn’t until I stuck my finger in the tank and noticed it took a long time to dry out and there was an oily film left behind. That is when we determined it was, in fact, jet fuel.

“You filled me up with jet fuel!” Tony yelled at me. “The heck I did! I handed you the nozzle and YOU filled it up!” The 100 octane truck was sitting right in front of you,” I replied. He had to agree with me; there was no mistaking the fact that we pumped fuel from the 100 octane truck. That was clear. I even confirmed that I filled up the truck with 100 octane from the fuel farm storage tank. That fuel had been delivered that morning, which I supervised, and we examined the paperwork that came with the delivery. It said it was 100 octane. It wasn’t until some time later that we determined there was a mix up at the factory and the driver had picked the wrong paperwork with the shipment. We now had a fuel farm full of avgas with jet fuel mixed into it.

A postscript to that part of this story is we had the Mallard on its way a couple of hours later and the oil company paid for much more than the drinks the boys had in the bar that morning.

So back to my checking new pilots out. It was about midnight; it seems like it always midnight when you’re hauling freight. There was a light drizzle falling, and it was cold; it seems like it’s always cold when you’re hauling freight. Did I mention I was tired? I was checking out a new guy that came to work for us. He was a fighter pilot in the local Guard unit and needed to get some multi-engine time. He was sharper than the average guy with the amount of experience he had and as fate would have it, it later turned out to be my boss for one of the jets I flew out of Pittsburgh for the airline.

Anyway, I was standing there in the drizzle explaining to him that I knew he was tired and he wanted to go into the FBO and get a hot cup of coffee and check out the vending machines and all of that, but it was important for him to stay and supervise the fueling, while it was taking place.

As I was explaining this policy to him, the fuel truck had arrived and the lineman placed and climbed the ladder and was in the process of pumping fuel in the nose tank of 02B. I don’t remember how much this tank held, but I knew it could feed both engines simultaneously when selected, and this was the first tank we would burn off after climb out. As I was explaining this, Bob (a name I made up to make the story more juicy) was listening intently while I droned on about the dangers of getting jet fuel pumped in by accident from the wrong truck.

“Like this one?” he said as soon as I stopped talking. I looked at the fuel truck sitting right in front of me, pumping fuel in the nose tank as I was speaking, and read the words, JET FUEL, written boldly on the side of the tank. We stopped the fueler immediately. Fortunately he had only pumped a few gallons in the tank by this time.

Fuel tester

If the engines are pistons, blue fuel is good.

After some discussion, we decided that we could take off and make it the rest of the way on the other four fuel tanks we had. The only thing we had to do was remember not to select the nose tank. If you think that I, or any of my pilots, are not capable of doing just that, you, my friend, are an amateur.

What are the chances of this happing? It turned out to be the perfect teaching moment, rather than the perfect storm. I am sure the line service guy learned his lesson. Bob couldn’t argue with the policy, and hopefully passed it on to others. But what about yours truly? First, I thought it was funny. It turned out to be kind of like a circus clown act. My droning on about safety, my student taking it in, while the lineman is actually doing what I am talking about not doing. You can’t make this stuff up!

Second, it reinforced something I already knew: you have to supervise the fueling, but the most significant thing for me was something that I have been experiencing since I started instructing. My students teach me more than I could possibly learn in school. You have to be an instructor first, and a good instructor as well, to appreciate my remarks.

By the way, when we got back, Ronnie, our lineman turned mechanic, drained the nose tank and the story had a happy ending. So the take away for you is don’t do like I see most pilots do. That is allowing for the fueling of their aircraft to take place without directly supervising the process. It is an airplane, not a car, boat, motorcycle, or lawn mower. The consequences of your failure to fuel properly are not nearly as challenging with them. If you don’t, the story’s ending might not turn out so funny for you, or your passengers, or your partner, or your children, or your… well, I hope you get the point.

    This is a good one. You never know where in an operation or process a serious mistake may have occurred. I can’t possibly stress urgently enough for pilots to do exactly as you have suggested.

      Bill David says:

      I’m glad you agree but, I am afraid you are in a small group that does. Most pilots nowadays have never been taught this, or they say something like, “I trust my fueler.”

    I always enjoy reading Air Facts Journal. I got about 4 sentences into this story before realizing that it was you! A good pilot is always learning, and that’s what I intend to keep doing. Thanks for the story. Hope to fly with you soon.

      Back in the day your dad rode shotgun in the “ole Beech,” for me often, so did your uncle Bob. Did your dad ever tell you the one about the cops detaining us in Waycross, Georia, at about three in the morning?
      I will have to check you out in my new ride, a Cherokee Six. I’ll see you up at Pee Lee if I don’t see you sooner.

    Bill, we bought Eric’s last Beech, I think it was called Bozo and we changed the N number to 666AK (daughter Amy) and put a few more thousand hours on it with many trips to Metcalf. The good old freight dog days, great memories and experiences but sure wouldn’t try to cheat fate now. Thanks for the good writing. Ron Kunse

      Ron, Bozo, 3602B, is the green Beech at the far end of the line up in the pic. She never got our custom paint job. She was the one in this story and she is in another story I’m writing which caused me to think, if I was a fly in the cockpit of that airplane over it’s life, how many stories would I have?

    Bill, you’re right on this very important point. I’m a retired now after 36 years as a corporate pilot, but I always supervised the fueling of the bizjets that I flew. I wasn’t too concerned about the fueler pumping avgas in a single point receptacle, but I always wanted to ensure that he pumped the quantity that I ordered and that the fuel cap and door were secured properly. I had some good conversations with some of these fuelers and gave the young budding career pilots advice when I could, and would usually tip them with a five. When my son worked the line, the crazy stories I heard just wouldn’t stop. The new line guys were given minimal training, and most had no aviation background and didn’t know a Learjet from a Citation. Watch out for an airplane with ‘turbocharged’ on the cowl. Most of these neophytes thought they were turbines. Bob Hoover’s Shrike Commander got mistaken for a turbine powered Commander (turboprop) and that’s how he wound up with a load of jet fuel. A 172 ordered 10 gallons of avgas one day where my son worked, and received 1 gallon. They ran out of gas on the way back to their home port. Guess the pilot didn’t supervise the fueling and didn’t read his receipt. The fueler was a new guy. One day the newbees towed an airplane thirty feet before they figured out that the reason the wheels were skidding across the ramp was that the parking brake was set. One day a nose chock was jammed under the front wheel pant of a Cirrus, and the line guy couldn’t get it free. No worries, the supervisor, no less, who was driving the tug just pulled with the tug until the nosewheel bumped over the chock, cracking the nose fairing, not too mention the stress applied to the nose gear. I don’t know why the FAA has never seen fit to require certification for such a critical job.

      Dennis, in my story I only mentioned a few incidents that I was very close to but, like you, I knew of more. Enjoy retirement, I am.

    Matt A. passed along your article – great read! Having only dealt with one misfuel in my Airport/FBO management career, it was jarring enough to force the changes that needed made so it never happened again. I’ll never forget the sound of my lineman’s voice when he called to notify me of the mistake, he was clearly shook, but caught the mistake while just finishing the fuel order. A ton of Jet fuel went into that piston twin that day, but I can tell you we had a thankful owner/pilot, who coincidentally made the remark that he wished he was there to supervise the fueling instead of calling it in from the hotel before their departure. I bet you can guess the type of twin piston involved.

    Thanks for your words of wisdom, sir. See you around!

    Airplanes and fuel trucks are not the only things that are misfueled.
    A long time ago at an airline far far away an interesting fueling event occurred.
    After a number of flights, the lavatories became well used bringing about complaints from the flight attendants.
    During our next turnaround we requested that operations have the “lavs” serviced.
    Later in cruise flight we received a message from dispatch telling us to lock the lavatory doors and not allow anyone to use them.
    When asked why, we were told that when the lav cart driver was told to fill the lav cart with gas he did just that!
    As a result our lavatories were filled with a mixture of “Blue Water” and gasoline.
    The flight attendants did a great job of keeping the lavs closed, and after landing maintenance dealt with the tainted blue water.

    Great read, I couldn’t agree with you more! I bought a 1946 J3 on floats in 2017 that Tony was the original owner of. So I searched online for him and read about his flying business starting after WWII delivering newspapers along fish camps on eastern shores of Michigan among other adventures. I have since sold the J3, but I sure wish I would have had the chance to talk some flying with Tony!

    Thanks Again,

      Tony was my buddy from the time I went to work for him in 1972, till he passed away just a few years ago. The knowledge and experience he gave me was priceless. My dad taught me how to fly an airplane, Tony taught me how to survive in one. I miss him.

    While I have yet to have my Jet-A pumped into my aircraft, I know other very careful pilots who have. A friend who was a very experienced pilot with lotsa GA and military flight hours had his a C210 topped with a tank full of contaminated 100LL just the same way the author did… from a mix up (poor pun) at the fuel farm. A few years later an unsupervised AND untrained fueler at my home field put 54 gallons into a high performance Piper. In neither case did the pilot test their fuel before engine start. The C210 got a new engine, and the Piper pilot got a funeral. I’ve also found water in the tanks of aircraft left outside. Another pilot acquaintance flying a supercub DID test his fuel before takeoff from a back country strip where he spent the night. Rain added undetected water to his tanks. Sitting in a normal 3 point position the water in his supercub collected behind the quick drains… and went undetected.
    His engine quit when a slug of water reached his carburetor at 300′ agl just beyond the end of the runway. He and his wife survived the crash with major injuries.

    Lessons learned?

    Supervise fueling. And pay attention to fuel truck markings.

    Always check the fuel for Jet-A after any refueling (the easy way is to drip four or five drops onto a piece of paper before fueling — Jet-A doesn’t evaporate completely.

    Check the fuel for solid contaminants.

    THINK about where water will collect in your tanks. If flying a conventional gear aircraft (nose wheel on the tail) you likely have to LIFT the tail to accurately test for water or solid contaminants.

    It goes without saying (but I’ll say it anyway) … don’t start the engine until you are SURE that all contaminants are removed from your fuel!

    Two stories. This is VERY easy at the gas station as well with diesel/gas. Some stations are yellow for diesel, some green up here!? I pulled up to a green pump on my bike and was warned by another biker at the next pump. Just then we heard an SUV driver overhearing this convo swear loudly opposite us..yup. The 2nd story was a company Islander, fuelled up with jet fuel in the high Arctic. A language barrier, and not supervising gave them a real scare as the engine temps both red lined out over the open Arctic Ocean. They made it.
    Footnote: this A/C had been rebuilt earlier after ditching because of this same issue ( another company) and the lease company took the plane back after this close call.
