Microbes Again

[pelmet]

From TSB via Google Translate...

C-FSEF, a Cessna 525B operated by Airsprint Inc, was operating flight ASP574 under the rules of
instrument flight from Port-Menier airport, QC (CYPN) to Port-Menier airport, QC
Rimouski, QC (CYXK) with only 2 crew members on board. During the initial rise of
CYPN, the ''FUEL BOOST ON L'' warning light came on in the cockpit.
The crew then continued the climb and declared an emergency with the air traffic control unit
when the aircraft passed 8000 feet. The crew requested a diversion to the airport
Michel-Pouliot from Gaspé, QC (CYGP) and climbed back to 18,000 feet. On the way to CYGP,
the crew received the message “ENGINE CONTROL R”. The quick checklist has been activated
and the message went out. ASP574 then landed safely on runway 10 at CYGP. THE
maintenance department replaced the left ''Fuel Oil Heater'' which was found contaminated with
microbial growth. The tanks have been inspected and the ''Fuel Oil Heater'' on the right
changed as a precaution.

Anybody here had microbe issues?

Yes in a C-208 in South America. That led to an engine failure (flame out) on the ground while taxing out (Thankfully!).

Someone in the Mx department was found to be selling our anti-microbial additive to the competition!

I know it's not needed, but I like a fill of "additive" fuel every once in a while..kills any growth but may cause a filter bypass when the scunge flakes off

What are you talking about? re: “I like a fill of additive”…

It’s a Mx event. Not discretionary to the PIC on a wing, a hope and a prayer.

A lot of operators will tell the fueller no additive as a standing order despite their aircraft POH requiring it. Next thing you know their fuel filter is full of ice, or in this case I guess bacteria.

It should be noted that Prist (additive) isnt known for its biocide properties. A separate product such as Biobor JF is used for that purpose.

That's good to know. I always thought Prist was antimicrobial.

Actually TPC you may want to check the PT6 type certificate. The PT6 has a whole gamut of approved fuels . JetA,A1, Jet B jp4,jp5, avgaz, P50 and maybe used with or without additive. Some operators cheap out because of the extra few pennies... If you aren't flying much or operate in a humid environment the occasional fill with biocide additive may stave off "algae growth". One of the guys I know just switched to a cj from a tbm850 because of a filter bypass light (water in fuel) and yes it has a fuel oil heater. So no it is not a maintenance event.

^ the butchery and misquotes abound….

You are talking additive? Like you stroll up all swagger like to the cute gal at FBO counter and say «with Prist and Please madame » because if that’s what you are referring to…

The additive of a biocide is a Mx event (in 4 countries that I’ve encountered Mx releases in) and typically the PIC would be aware of that Mx release. This may not apply to you in colder temp countries where microbial colonies don’t tend to thrive in fuel tanks.

From the Prist web site:

What biocidal/antifungal properties does the PRIST® Hi-Flash™ Fuel Additive have?

PRIST® Hi-Flash™ Fuel Additive meets ASTM D4171 and MIL-DTL-85470 (Current Revision Issue) specification for DiEthylene Glycol Monomethyl Ether (DiEGME). The primary purpose of this chemical is to prevent freezing of water in the fuel system of aircraft. It is this property that is covered in ASTM and/or Military specifications. Neither of these specifications contains any biocide requirements.

Prior to 1994, PRIST® was made to a Military Standard MIL-I-27686, which specified Ethylene Glycol Monomethyl Ether (EGME). Provisions were made to have this product certified as a pesticide with the EPA. This allowed the product to be advertised as having the ability to retard growth of microbes in aviation fuels. The correct term is for the additive is microbiostat (-stat means it controls or retards growth by putting the microbes in a static condition), it is not a true microbiocide, (-cide means it kills microbes).

With all of the new EPA requirements, it became economically prohibitive to certify the new DiEthylene Glycol Monomethyl Ether, DiEGME based additive as a pesticide. Summarizing the above, it is widely believed that DiEGME does have a retarding effect on microbial growth; however, we no longer officially claim this property for the PRIST® Hi-Flash™ Fuel Additive.

Google is your friend, or do you believe that's only for "sheeple" too?

It was a Covid joke, you retard. Do you have to be so fuckin awkward?

Stick to your day job - if you have one. Comedy just ain't your thing.

Series 9 pc12's needed prist. Then some tdg egghead got involved. And made it near impossible to ship prist, unless the operator was remote n only means of transport was in its own aircraft under an exemption. . N alot of paperwork. As a nation we used to build alot of great stuff now it takes 10 years n a study to build an outhouse .

n lets clean up the language here eh- yur supposed to be educated. you just show your inability to use the large vocabulary n mastery of english when the potty mouth run amok

Can someone translate this from “boomer”?

[Old fella]

Hilarious …… entertainment value priceless “ boomer”, “ retard” , “ sheeple”. Surprisingly Trudeau’s name hasn’t come into the discussion yet unless ole Rookie shows his face.

You are definitely not showing “mastery” of the written English language in the above post, maybe look up irony

There is most definitely an entertainment value on some threads and the various commentary.

[Meatservo]

Entertainment is the only remaining purpose of this antiquated forum. I stand by my use of colourful pronouns, expletives, and epithets. It is very funny when one is responding to a thread about microscopic life-forms to make reference to the shameful continued existence on this site of a sub-forum dedicated to the conspiracy theories and frustrated rantings of what seems to be a good cross-section of Canadian society’s Epsilons, most of whom seem to have somehow earned a pilots’ license. And then to be censured by someone using education as a moral high-water mark in a post rife with spelling and grammar errors. This is all gold, and In congratulate myself for interrupting a serious conversation.

So, in conclusion:

1) Anaerobic microbes can thrive on the miniscus of a water droplet suspended in jet fuel
2) These microbes and their by-products can clog fuel filters
3) These microbes were engineered by a lab in China with the intention of disrupting Western reliance on air travel. They are being abetted in this dastardly plot by the freedom-hating cretins Justin Trudeau, Chrystia Freeland, the World economic forum, Snowflakes, Softies, Hillary Clinton, Giselle what’s-her-name, and the lizard people
4) Blue Masks are not sufficient filters for these microbes
5) Only the bravery of Donald Trump and Canadian truck drivers will see us through this crisis, but only through a careful and co-ordinated program of horn-honking, public urination, and country music
6) Has anyone considered bleach and/or ivermectin as a possible alternative to Prist?

That’s some entertaining stuff there, thanks for a morning laugh!
