Conquest Fuel Heaters
 

Have just added a C441 to our small fleet. Bit of a pain adding FSII to the fuel. can anyone give me any info on this stuff and if anyone knows of a 441 that has fuel heaters. the engines are TPE 331-8.

Do not believe that the CE441 had any option for fuel heaters. Try a search of http://av-info.faa.gov to see if there are any STC's available. The additive may be your only option.

Never needed the additive, and went to FL300-350 all the time.

Fuel additive (anti-ice) in the C441 is critical. As all experienced pilots know and engineers worth their salt will tell you that it only takes a microscopic drop of water or ice chip to completely destroy an FCU.

If you do short haul in predominantly warm enviorons then 'avgas' will kill the 'bugs' that reside in Jet A1. Just a few litres every few weeks will kill the fungacide.

Zeke: You should have more sense, just remember your playing with the aircraft certification, next stop a coronial inquest!!

Office update,

The FAA C441 TCDS A28CE says ....

I will check up on the fuel that we used to use to see if it contains diegme in the prescribed quantities. The company that I used to be with had over 8 years of experience operating the type, and the guys working there were the only ones with the ability to service the FCU’s for the region (break out boxes and bench FCU calibration gear).

The electronic FCU on the conquest is unique amongst the garrets when you compare what the pitch/speed power levers actually do.

Office update,

Just checked the Material Safety Data Sheet for Turbine Fuel, Aviation — Wide-Cut Type

Regulated Components

• Kerosene 40-70%
• Naphtha 30-60%
• Ethylene Glycol Monomethyl Ether (EGME) 0.15%
• Diethylene Glycol Monomethyl Ether (DIEGME) 0.15%

Diegme is the active ingredient of FSII (Fuel System Icing Inhibitor), as it is above the prescribed minimum quantity no additive is required.

:rolleyes:

Thank you for the informative responses. Quite keen to hear further discussion as it seems a fairly stupid requirement to play around with carcinogenic type additives in this day and age.(ie cans of Prist).

Baza,

Just find out exacty what has already been added to your fuel (the MSDS is for our location), if there is enough FSII already in it you wount need to handle those carcinogenic additives.

:rolleyes:

Hold on, Zeke. What you describe is the old wide-cut JET B/JP-4. The highly volatile stuff that isn't hardly available anymore.

JET A/JET A1

• Kerosene 100%
• Napthalene 0.04%

JET B/JP-4

• Kerosene 35-65%
• Napthalene 35-65%
• Benzene 0.1-0.4%

The two fuels are vastly different. Any anti-icing properties found in the wide-cut are no longer relevant, as it can't hardly be purchased.

Cardinal,
To quote transport canada ....

"Jet B is a wide-cut kerosene with lighter gasoline-type naphtha components. It’s widely used in Canada, contains static dissipator and has a very low flash point."

My understanding the F34, F40, aand F44 fuels all have the FSII in them.

Zeke,

Appreciate your input, good man!! however wide ranging comments such as your first post are very misleading and deceiving. You should have first stated that you were in Canada?? and that you were using jet B a type of fuel not widely available etc especially in most parts of the world.

Younger pilots reading your post might think that you know more or are in possession of the latest 'gen' re the use of fuel additives. Theye may even be lulled into a false sense of security by your posting.

You have done a lot of research, for that I thank you as I did not know Jet B was still available, too low a flash point! For the sake of the younger pilots please be careful in your wording.

Right about the fuel. Investigation here shows that it was JetB. JetA that is available in this country does not contain any additive so still looking for an operator that has fitted fuel heaters to the TPE331-8.(they are standard on the -10)
