How do I come to terms with an “Imperial” valve in a Aeronca 7ac?

Leave a comment

Good Fuel Valve Gone Bad….

My family has owned and operated a 7AC since 1976, with many happy years of flying, kiddo’s soloing and so on.  Good lord willing, there will be many happy years of that in the future.

Since I was old enough to pay attention to the airplane, the fuel valve has been a recurring nuisance.  Every couple of years, we have rebuilt the valve, carefully polishing the mating surfaces with jewelers rouge, replacing the packing, leak checking on a bench stand,  to varying degrees of success.  Recently, the valve had become difficult to turn, but other than that, it worked correctly, and did not leak.

 

We experienced an occasion where the engine lost power, and later investigation revealed the torque rod was not fully selecting the valve OPEN.

After that difficulty we decided to install a “Burl’s Alaska” PMA fuel valve.  Plenty of info at www.burlac.com.

The (choke…) $400.00 valve arrived and we fitted it, after ordering new AN fittings for the fuel line.

The documentation was surprisingly complete, and included the STC, PMA paperwork and an approved drawing to modify the existing torque rod to the fuel shutoff lever.

All in all, the valve and associated machine work looks first rate.  The STC documents are in order, and we are hoping  for many years in service in the future.

 

 

F900 Troubleshooting

How do I come to terms with Fault Codes in a SPZ-8000 for F900?

Here is the simple break-in to get the codes:


REMEMBER::::::

If you pull the breakers in the air as a matter of troubleshooting, the codes are lost!

If you land and power down airplane, the codes are lost!

 

If you are using this diagnostic on the ground after powerdown,  YOU ARE WASTING YOUR TIME!  It’s like giving a dog investment advise.  It’s not helpful, and it anoys the dog.

 

 

Flight Fault summary must be performed after aircraft lands, before power is turned off.
YD and MTRIM must be dark.
At the copilots left elbow in the engineers Panel.
There is a Bat Handle switch labeled “AFCS TEST” or some such.
Select it up.
The ID802 panels will self test.
Then , When they are finished you should see “01 – FGC TEST?” Do NOT perform the test now.
Instead, push the LAFCS button which in this case acts as a “Previous Screen” button.
A few screens back, you will get to “98 – FLGHT FAULT SUMMARY”
Push “RESET” to get to the flight fault screen.
That should show the codes for the LEFT computer.
Take a picture of that screen.
Now press reset again.
That should show the RAFCS faults.
Take a picture of that screen

Here is the Spreadsheet that unwraps the Hex code to plain english…. or as plain english as a Honeywell engineer can make it.

 

This one runs under Libre Office:

SPZ-8000-Flight-Fault-Summary   .ods

 

 

This one runs under excel:

SPZ-8000 Flight Fault Summary

 

SPZ-8000-Flight-Fault-Summary – this one is from Augusta

I think these spreadsheets were written by Terry Markovich.  Genius that ran Duncan TEB back in the day. Super clever.

here is an example fault code

how do I come to terms with EBIS peculiarities?

This will force it each item to start on a new line when using the log book labels.

You need to use the separator: \n

This is set in View > Preferences > W/O & R/O tab > Log Book tab > “Label Separator”.

how do I clear out excessive STORED discrepancy text

You can remove the action items by going to View menu > Action Items > (make selection).  If you wanted to delete ALL action items for all parts of EBis, you can do this from the Admin Menu > Data Admin Functions > Delete All Action Items.

why can we not have RTS statement on “Maintenance Printout”
Currently the maintenance printout was not meant as a final printout, so there is no statement that can appear on it.  The log book labels & the customer invoice were meant to show the actual statements.

 

Unfortunately the page 1 of x cannot be removed.

As far as limiting their access to the action items, please uncheck the edit action items option in their user account (please see attached). Please let me know if you have any more questions or if I can further assist you.

 

Cheers,
