BARRY E. FITZGERALD replied to the topic 'Aspen Avionics E5 Evolution' in the forum. 9 hours 1 minute ago

I ‘m happy with the Aspen.
I all one unit.
I installed it myself.
Happy with my choice.
I would recommend Aspen.


JOHN QUIMBY replied to the topic 'Aspen Avionics E5 Evolution' in the forum. 11 hours 36 minutes ago

Barry - we were debating today the pros and cons of the Aspen vs two G5’s. Someone said two G5’s provide redundancy and someone with experience with the Aspen mentioned the display was crowded. Any thoughts based upon your personal experiences?



JOHN QUIMBY replied to the topic 'Seat Rail AD 2011-10-09' in the forum. 11 hours 42 minutes ago

Steve - I pulled the seats and carpets today and cleaned off the seat rails. My IA did the inspection and there is a small crack that has not changed in two years. The crack falls within the acceptable level of the AD. There are no other cracks anywhere on the rail. My IA went through the required checks on the seats and they were all within tolerances. I cleaned and dry lubed the rollers and they are ready to go back.

I’m hoping to start prepping for the annual and I was reading your article:

I followed your article guidance with my A&P last year and wondered do you have the steps in a spreadsheet or document? I’d like to make electronic notes.

JOHN QUIMBY replied to the topic 'Where to purchase Seat Tracks' in the forum. 12 hours ago

George - how did the seat rail project go? Did you use the macfarlane screw kit or the OEM rivets? I went through the AD today with my IA - I have a small horizontal crack but nothing is out of tolerance per the AD. I couldn’t believe the tolerance for the elongation of the holes it was something like 2X the normal size. The IA said he believes mine have been replaced once already.


Charles Gill created a new topic ' fuel flow from left and right tank' in the forum. 19 hours 59 minutes ago

When in flight the fuel flow from the left tank is three times as much as from the right tank when the selector switch is on both. When on the ground and draining the tanks with the fuel line from the fuel line to the engine compartment the flow rate is the same form both tanks. I have timed how long it takes to drain 20 gallons from each tank. There is good cross venting between the tanks. I have not allowed the left tank to run dry in flight while on selector is on both as I am not sure what will happen. The aircraft is a 1962 cessna 175C with a Franklin 335 engine and a constant speed prop. Plane preforms great but I cannot figure out the different flow rates from the tanks in flight. Any suggestions?


Any info on tailbeacon installs on 172's?

Jason Hughes replied to the topic '175A Push/Pull Switches' in the forum. 2 days ago

I finally got around to replacing my master switch with new old stock and it didn't change anything. I still have a slight, rapid oscillation in my ammeter. I'm wondering if it isn't the ammeter at this point. I have a USB outlet in my cigarette lighter and it doesn't flucuate the volts, but I realize that is comparing apples to oranges.

Does anyone have any other suggestions on what to look at? I've changed the voltage regulator (which did help eliminate most of the flucuations), all the wiring associated with it, and the master switch. I've also cleaned the connections at the master relay and battery terminals. Maybe I need to slowly start replacing all the wiring from the master switch to the bus and ammeter. I'm sure that wouldn't hurt anyway as most of the wiring looks original.



Richard Lyon created a new topic ' APS Power Wheel' in the forum. 2 days ago

Could anyone help with a source for an APS Power Wheel?

It doesn't seem to exist as an App and the original publisher doesn't seem to exist any more.

I've tried all the usual sources.....

Thanks in advance


Lyle Mann created a new topic ' 1957 Cessna 182A fuel sensors' in the forum. 4 days ago

Replaced the Cessna fuel sensors with CIES sensors on our 1957 182A. Will include new gaskets. Make offer


JOHN OWENS replied to the topic 'Seat Rail AD 2011-10-09' in the forum. 4 days ago

Since the Shop had experience with this AD, I used their guidance and they supplied the Rivets. Only rails purchased via McFarlane. Also, a Shop can sometimes purchase the Rails for less than a retail/owners quote. (Another good reason to use a Shop with McFarlane account history.) I just wanted to give the Labor guys the best chance of timely success, and therefore they controlled the parts choice in advance.


JOHN QUIMBY replied to the topic 'Seat Rail AD 2011-10-09' in the forum. 5 days ago

John - great information thank you. I’m curious that you mentioned the rivets. Did you choose to go with rivets vs. MacFarlane screw kit Part # SR6-SCREW-KT SCREW KIT? They must be special because they want to charge $115 for it. I’m assuming but need to call that it’s actual a bolt kit.
Update: I’m about to tear down my plane and have my annual done on my field. I missed the weather window to get my plane to the new A&P. My local IA is going to review my seat rails and then I can order the parts from MacFarlane. The seat rail price has gone up by $100 since I first looked in May 2018. I guess they can dictate the price since they are the best game in town.


That's very helpful, Steve - especially that useful link for suppliers*, which we hadn't come across before.

I'll discuss this with my engineer, and check exactly what testing has been completed. We'll probably start off by replacing the diodes, but we'll see the results of the test.

PS We're in Kenya, by the way.
PPS *We were quoted $152 by 'Spruce for the board, but doubtful we're going to need it.


Hi Richard;
This link lists companies that say they have that part:

It lists for around $250 over here.

How do you know your diode board is bad??

From the service manual it appears that the diode is installed to prevent damage to the alternator diodes IF the ground power plug is incorrectly wired (positive to the negative pin or vice versa) or it's inserted upside down.

Quote from the service manual "A silicon junction diode is connected in series with the coil on the
power contactor so that if the ground power source is
inadvertently connected with a reverse polarity, the
external power contactor will not close."

I pulled the component part numbers out of the diode board. They are 1) diode-20h3p is superseded to 1N3881; 2) fuse x-26263 is superseded to VL7-.75 and 3) resistor S1091-5. You may be able to save some money and time if you order these descrete parts, provide you're allowed to repair the board in the field in Nigeria.

If the diode has failed, I don't see how that would prevent the ground power receptacle from working if the ground power plug-from your ground power source- is wired correctly and the plug is inserted into the airplane correctly.

Have you tested the wiring to the contactor? Have you tested the windings in the contactor for an open circuit?

Hi John;
Thanks for weighing in with your experience in changing seat rails.
Valuable information


Jeff Strouse created a new topic ' Up grade engine analyzer' in the forum. 6 days ago

I have a 1978 T210M and thinking of upgrading my JPI 800 to either a JPI 930 which will use the current wiring so no changing sensors. Or the MVP50P. The MVP50P has a weight and balance program and a check list. Any thoughts or advice ,experience with the JPI 930 or the MVP50?

Regarding the Seat Rail labor.
My 182 E needed both L and R seat rails replaced. I knew this going into the Annual and had already spent the money to obtain the needed parts at McFarlane.
I asked for an estimated amount of labor hours and how many times the shop had replaced Rails. 12 to 16 hours was the estimate, and they went over the rivet, template process in detail. Shop employed a very experienced IA with decades of Cessna experience and two A&P.
Result: as advertised, 16 total hours of labor (both seats.) They also added carpet snaps, did some corrosion floor control with in that time.
Planning ahead benefited not just my budget, but gave the shop a clear timeline to manage this task. The annual and this AD took 3 days, and my airplane was in and out of their shop due to planning and a little pre inspection.
Take away, find a shop with a couple people that have done this AD .


I need to fix our external power receptacle, which at the moment is u/s. Our engineer has recommended, as a start, to replace the diodes, and I've been quoted $152 for the diode "board" (Part number #1570043-15).

Does that sound reasonable? Maybe that includes a pair of diodes? Information is a bit sparse, as we're based in Kenya.

Any advice on renovating this particular kit would be appreciated.

Thanks in advance.
