Should have known that Steve would find it! Steve, if you forward that to me I can also get it posted.


STEVE ELLS replied to the topic 'Service News Letters' in the forum. 2 days ago

Dear Ed, In the future, please identify the model Cessna, and aircraft serial number when requesting assistance. That will help me focus my efforts.
I sent SNL85-24 to your email address.
Happy Flying.


STEVE ELLS replied to the topic 'Carb heat extraction point' in the forum. 2 days ago

Hi Gary;
If you can determine who fabricated your new exhaust stacks/collectors, they can most likely supply you with a shroud that will fit your new parts.
The other option is to remove the plug, if the removal won't damage the shroud. This should allow you to use heat extracted by that shroud as your carb heat source.
The sticking point is: is the new muffler a similar size to the old part? This is important because there must be enough surface area to supply the amount of heat needed to comply with certification regulations; and to de ice your carburetor in all foreseeable conditions.
The carb and cabin heat systems work by taking in ram air, circulating it around the outside of what some call a muffler and then ducting it to the carburetor heat box or the cabin. There are 2 ram air inlets on your airplane; they must both be open and connected to the shroud.
Let me know if I can help further.
If I'm still missing something, please reply; attaching photos helps.

Hi Ed,
I also can't find an SNL with that number. What's the subject of the SNL? Perhaps we can locate it that way.



Gary Ebken created a new topic ' Carb heat extraction point' in the forum. 3 days ago

I'm a new member and have a new to me 182B with O470L engine.
Looking in the IPC it shows the carb heat air getting extracted from the muffler shroud.
The outlet flange on the muffler shroud is there but has been welded closed with a block off plate at some point previous.
The old exhaust had a heat muff on #2 exhaust stack to supply the heat to the carburetor.
I had to replace the exhaust stacks/collectors, and the muff that fit the old #2 exhaust stack will not work on the new one.
My question is.
Do I try to locate a heat muff that fits the new #2 exhaust stack or remove the plug someone welded on the muffler shroud flange and utilize that as the heat source as per the IPC?

Someone told me to read SNL 85-24 as it addresses an issue I have. Trouble is I have looke all over for that publication. Cessna, Cessna Flyers, CPA. Can’t find it. My friend can’t tell me where he saw it. Can any of you?



STEVE ELLS replied to the topic 'IO-520 hot cylinders' in the forum. 7 days ago

Hi Scott;
I suggest that you get your mechanic to do the same checks and, if necessary adjustments I spelled out in my first response to this thread. Make sure the fuel flows are set up in accordance with the engine maintenance manual, replace all spark plugs with greater than 5,000 ohms internal resistance, and make sure the fuel injection nozzles are clean.
If you have GAMI nozzles installed they must be installed in the proper cylinder--they can't be swapped from one cylinder to an other.
If you don't have GAMI nozzles, you can swap the FI nozzle from the hot cylinder to one that cooler and see if the "hot" follows the nozzle. The high temps might be nozzle related.
I suggest to go to the GAMI website ( and do the Lean Find test to determine what the EGT spread is on your cylinders/nozzles. It it's out of what GAMI suggests, the next step would be to get a set of GAMI nozzles for your engine.
Please let me know what you find.


Scott Hutchinson replied to the topic 'IO-520 hot cylinders' in the forum. 1 week ago

I have a T210 as well. #5 runs consistently hot, and it's nearly impossible to run at 8000 feet with 2500/30" and get the temps down below 410.

I'm curious if anyone has a recommendation for someone who can look at and fix the baffling. We're based in Houston, but travel a lot in the plane so taking it someplace isn't a big problem.

STEVE ELLS replied to the topic 'Seats from a 182R in a 182M' in the forum. 2 weeks ago

Cessna changed the seat rail system when it restarted the single engine program in 1996 due to a large number of lawsuit payouts by juries that were convinced that Cessna should be responsible for airplanes it hadn't; sometimes for decades.
Cessna did issue a number of service bulletins alerting owners and mechanics to the need to thoroughly inspect seat rails and seat rail locking systems. Cessna even offered, free of charge, secondary seat locking systems to owners of single engine Cessnas built prior to 1996.
The seat rail systems on single engine Cessnas manufactured since 1996 is much stronger than the older system and the "feet" on the seats are built to capture the new seat rails.
The new seats can not be installed on the pre-1996 airplanes unless the seat rails are changed to the newer type.
I haven't heard of anyone who has installed the post 1996 rails system on a pre-1996 airplane but it's something that would be worth exploring.
Happy Flying

Does anyone know if the seats from a 182 R will fit in my 182 M. Are they the same rails and attach points? Thanks, Brian Rau


Peter Hamilton replied to the topic 'Who's doing what for ADS-B Out?' in the forum. 2 weeks ago

I went with the Freeflight Systems RANGR 978 XVR, It was an all-in one ADS-B In and Out solution. It uses a WiFi transceiver to link to iPad and / or iFly GPS. The WiFi linkage allows multiple devices to be connected. I use ForeFlight, and love it, but sometimes the iPad is just not sunlight readable, so I went with the iFly GPS. This system can also be wired to Garmin 430W/530W GPS if desired. I did have an older King Transponder that needed to have a digital encoder installed (actually not too expensive, believe it or not), as the Freeflight "sniffs" the transponder code signal so whatever it is broadcasting the Freeflight can match. It was a cost-effective solution at the time (2015) .

Thanks for the quick response. My plane is going in for annual in a few weeks, so this issue will be addressed.

STEVE ELLS replied to the topic '172R fuel flow gauge intermittent' in the forum. 3 weeks ago

I believe that instrument is a Rochester EG2615-06021 FF/EGT gauge.

I also believe that the sensor data is fed through a Garmin GAE 71 Engine/Airframe unit.

If the connections on the sensor to wiring and the gauge to wiring have been proven, the next step it to check the wiring at the GAE 71, a Garmin Engine/Airframe Unit.

I do not yet have a wiring manual for that airplane so I can’t confirm the belief that the GAE 71 is the interface between the sensor and the gauge.

I will try to get more information for you tomorrow.
