Over the last 6 months, when I sump fuel out of my 1976 Aztec, I see white stringy stuff floating in the fuel. The fuel supplier at KDPA (Phillips) upon looking at a sample couldn't explain what it was. I asked maintenance to investigate. Tanks were drained in order to access the bladders. The fuel cells were coated at the bottom with a brown sooty slime. Bladders were replaced in 2012. Maintenance contacted the fuel bladder supplier who stated that this could be a result of different fuel suppliers haven't different fuel formulations, and the brown soot may be the result. The fuel filters were coated with this soot. Has anyone ever heard of this or experienced this?
I've attached a few photos, along with one photo of a special surprise in the left tank.

Rockland, ME (KRKD) - Flying up the coast of Maine is beautiful. The airport is located at the end of a peninsular and is less than a mile from a museum of transportation with antique, planes, cars, and other vehicles. The town of Rockland is charming and has many good restaurants and a great museum.
In the June 2018 issue of Piper Flyer, columnist Kevin Garrison discussed a few of his most memorable flights.
Where have you flown that has had a special significance to you? What are the places and airspaces that have made you happy, gotten your fun meter pegged, or given you goosebumps?
Tell us all about it!
How did your last annual go? It looks like you might be coming up on due again? Let me know if you're happy with the last shop, and I have a recommendation for you if not.
Are there fellow Canadian aviators in this group that have experience with using a US avionics shop in the north east? I'm based in Ottawa, Ontario and trying to find a reputable avionics shop to install a customer-supplied GNS480 in my 1972 Cherokee 140. Some of the quotes I've seen from Canadian-based shops blow this project right out of the water. Would be interested to learn what experience others have found having avionics work done in the, say...New York, Vermont, New Hampshire, Maine and Pennsylvania area?
I’m looking for a replacement door lock for my 1965 PA28-180, any helpful ideas ?
I have upgraded my response; It follows:
The GDL 82 is Garmin’s low-cost solution to the ADS-B “Out” mandate. But if you don’t already have a WAAS (high integrity) GPS receiver to feed position data to the GDL 82, you will have to upgrade to a unit with a WAAS receiver. If you do have a WAAS receiver, you can buy the GDL 82 for $1799. It will work with your KT76A—provided that your KT-76A is married to an encoder—or with any existing Mode A or Mode C transponder.
The installation consists of installing the GDL “box”, that measures 3.3 inches by 1.5 by 9.2 inches at a convenient place upstream of the transponder antenna in the coaxial cable between your transponder and the transponder antenna. That part is very easy.
The second part requires the installation of a GPS antenna. Since GPS antennas must be mounted on an upper surface of the airframe, you’ll need to mount the antenna—as near the centerline of the aircraft as possible—and remove enough interior to route a coaxial cable from the antenna to the “box.”
The GDL 82 will not work with Mode S transponders. There’s not much more to it. The avionics installer will need to input some confirmation information, and you’ll need to fly a confirmation flight but that’s easy.
The GDL 82 transmits on the 978 MHz and is called a Universal Access Transceiver (UAT). Installation fulfills the 2020 mandate for ADS-B Out.
ADS-B “In” information includes NEXRAD weather, traffic, METARS, TAFs, NOTAMS, TFRs and other very helpful information in your cockpit.
There are different ways to display the “In” information. One commonly used method is to send the “In” data via Bluetooth or Wi-Fi to an Electronic Flight Bag (EFB) app on an iPad or other brand tablet. There are a bunch of very good EFBs out there such as the Garmin Pilot, the Appareo Foreflight, the Seattle Avionics Fly Q and others. Receivers can be battery-powered portable units such as the Garmin GDL 39, the Appareo Stratus 2, and others. I use a Stratux ADS-B Dual frequency unit.
The main drawback of the portable units is the somewhat short battery life. Most units will work for between 4 and 5 hours on a charge. The Statux I have needs a portable battery to power it. I have 2 EasyAcc slim line battery packs that provide enough power for 8 hours of use.
Many portable units can be powered from a USB power output plug in the panel. I installed one in the same hole the cigar light was in. I got the one from Guardian Avionics; other suppliers include Mid-Continent Instruments and Appareo Stratus.
If you do not have a WAAS high integrity GPS to tie to the GDL 82, other options include installing a new transponder with a built in WAAS GPS and ADS-B “Out” capabilities such as the Appareo ESG and the Garmin GTX 335. These retail without installation for $2995.
There is a great deal of information about ADS-B at Garmin’s ADS-B Academy ( www.garmin.com/us/intheair/ads-b ) and in the avionics section of the Pilot Shop the Sportys website ( www.sportys.com ).
Hey Pete, I learned more as I was finalizing this question for publication in the magazine. The upgraded text follows:Hi Pete;
First off, your Janitrol should not be streaking black smoke clear to the tail. I expect you need to get into the heater and check the spark plug (or just replace it), check the spray pattern of the nozzle, check the fuel pressure (7.5 psi) and the output of the combustion blower. If any of these components are not correct, the resulting rich mixture will cause a sooty exhaust. You can download a Janitrol heater service and parts manual from Janitrol at: janitrol.aero/wp-content/uploads/2017/04...rs-Manual-New-s2.pdf .
This may not be the exact manual for your heater it will give you an exploded view of the heater parts and procedures to test the components.
Kristin Winter, who also writes for the Piper Flyer magazine and flies a PA 30 Twin Comanche reports that Easy Off oven cleaner is the quickest and most effective belly cleaner. She cautions that it must be used in a well-ventilated area, must be rinsed with water and wiped off immediately after application and then rinsed again.
Others say that Easy Off is very caustic and that they would never use it on bare aluminum, but only on a good painted surface. Since it is caustic it MUST only be used on a painted surface and MUST be rinsed immediately with plenty of clean water. It will attack bare aluminum.
Responders have also suggested using other less toxic cleaners such as GOOP hand cleaner (without pumice) and rags, Aviation Simple Green (must get the aviation kind) mixed 50/50 with water; Sportys and Aircraft Spruce sell a product called Aero Glaze Dry wash that others recommend.
There have been quite a few upgrades and improvement in light airplane combustion heaters recently. It might be time to pull the heater and send it in for an overhaul.
While there are built in safeguards on these heaters to prevent problems, there’s a lot of comfort to be had when you know the flaming fire in the nose of your airplane is in top notch shape and all the safeguards have been tested and are working properly.
Overhauls can be done at www.Janitrol.aero . Most West Coast flyers get their heater overhauled and serviced at www.aircraftheaters.com in Redding, California.
Sorry. I should have deleted. Sold along time ago.
Are your visors still available, can you post a photo or send to m,my e-mail ?

Looking for a set of front seats, pilot and co-pilot, for my Arrow. I know there are lots of seats that will retrofit. If you have knowledge of any around or can forward and leads or if you even may have a set in your hangar you are thinking of parting with to an awesome home, please holler. Thanks much.
Thanks Steve. I'll have maintenance check it out.

According to installation information of a Janitrol heater in place of the orginal Southwind heater the exhaust pipe should extend 2 inches beyond the skin and the angle of the scarf cut on the pipe should have the longest side forward. This creates a vacuum to help move the exhaust out into the slipstream.
I'm following up with some sources and will post their advice within the next couple of days.
