Posted: Sat Nov 10, 2007 11:11 pm Post subject: grounding question

What are people doing for ground wires for the nav, landing, and pitot heat?  Are you running separate wires for ground or grounding locally to the airframe?  This might be somewhat of a “primer war” question as I’ve heard some say always run ground wires and others say ground locally.  Aeroelectric says local ground for “non-noisy” items is fine.  Just wondering what others have done.  

   

If airframe what kind of hardware do you use to get a solid ground connection?  Do you use regular AN nuts bolts and washers or do you use something like a lock washer that has more bite maybe?  Do you cover the nut/bolt with anything to slow any corrosion being that you need to clean the primer off the metal at the point of contact?  

   

Yes John I’ll wipe the dust off the 43.13 J

Ben - 

  

 I grounded lights and pitot heat locally by riveting a #8  nutplate to the spar web - one in each wingtip, one near the pitot mount.   Socket-head cap screws and internal-tooth lock-washers secure the ring  terminals.  I didn't add any extra corrosion protection (I'll shoot  it with CorrosionX after paint), but I do use a little anti-seize on all  nutplates.

I spoke to a fellow -10 builder who is an AP and  was told to ground most things locally.  Logic was that the structure is a  very good conductor and "there is more of it."  Also, less wire, less  weight and less complexity.   I only installed one ground so far for  my Gretz pitot and used a nut plate and screw.  The friend suggested this  because of the locking function of the nut plate and solid mount.  I have  QB wings and they came primed with a wash primer.  I just drilled the holes  for the nut plate, deburred, and squeezed in some rivets.  Continuity is  good.  I will probably coat with some ACF-50 or Boeshield after  paint.  I have an EAA tech counselor visit soon and will pose this question  to him.

  

 Only one person's opinion.

In my RV-8A I ran a single #14 common ground wire to each wing, with an additional #14 ground wire for the pitot heat.  My thought was to avoid mechanical problems associated with using the air frame for ground (getting a solid connection, hardware coming loose, dissimilar metal corrosion between the connector and the air frame, hard point vibration source, etc.).  I plan on the same approach in my RV-10.  

   

I also used a Molex plug on the wing wiring to allow for wing removal for paint.  The plug is located in the wing root along with female and male BNC connectors for the wing tip antenna.   After paint I put RTV on these connections as an additional means for preservation.  The RTV is easy to peal off if I ever need to take a wing off again.

I have been using local grounding with brass nuts /bolts / and lock washers to minimize corrosion and give a better conductor than steel.  The primer is removed under the lock washer to insure good contact.

Nuckolls Book works for those with fear of reading the AC43.13.  Surface contact area always wins over internal or external lock washers.  They just retain the nut.  Anti-Corrosion compounds can help as well.  

   

At work, We use my beloved ProSeal on bonding strap attachments to keep environmental contamination to a minimum.  

   

As an aircraft gets up to reaching my own age, corrosion on ground connections produce unique and challenging diagnostic opportunities.

Answer #3 – Make an appropriately sized monetary contribution to Matt’s Matronics Annual Contribution List for November and receive a free copy of Bob Nuckolls Aero Electric in electronic form… then no dust is likely.

John my punches were inteded to be humerous… more as “beat you to your standard response” than anything.  

   

I own the latest version 11 of Bob’s Aeroelectric Connection and have read it front to back 3 times in the last several months.  Believe it or not my AC43.13 is quite tattered.  Both were consulted prior to my emails.  I like a healthy dose of information prior to actually making any decisions.  My experiences in my 32 years of life have proven that book smarts don’t always align with reality so along with the reading and research that goes with all the build decisions (which at times seems like its more than actually building) I like to hear what others have done and will do.  I take from those what I feel prudent.  

   

Thanks for your responses they are always valued and welcomed.

I'm grounding locally to the airframe (wing tips, tail structure,etc) 

per Aeroelectric recommendation. Will have ground bus for sensitive 

equipment.



When grounding to the airframe, I referenced Tables 11-14 & 11-15 in 

43.13. Very specific advice on grounding to aluminum airframe with 

aluminum washers and lock washer application. It was my first use of 43.13.



I have no useful experience with the results in this area.

Ben,  

   

The grounding tabs that Stein sells seem to work quite well riveted to the structure with no paint between.  The strobes I ground very close to the battery-airframe ground, the nav lights in the wings, landing lights and pitot heat I ground locally.  Everything in the panel gets grounded to the firewall.  The lights in the tail I run grounds back to the battery ground area.  The headset jacks I do not ground, but use the fiber washers to keep them isolated from ground.  Everything from the stick grip(s) I ground under the copilot seat, although most of those grounds are just grounding the switch so when it is pushed it connects that circuit to ground to tell the things to do it’s thing.

This echo what other have suggested. The plan is to locally grounding the noise producers with a nutplate arrangement removing the primer from under the electrical terminal. Insulating the head jacks with fiber washers and running all of the audio/radio grounds to a single point ground on the fire wall. My understanding this should eliminate the possibility of a ground loop noise. An exception to this is the strobe wire shielding which is grounded only back at the power unit not out at the wing tips, again I've read this helps with the ground loop issue. 

  

 Idea Industries makes an anticorrosion  gel for aluminum to aluminum and copper to aluminum electrical connections. It is not an aircraft product, however I'm sure there is an equivalent aircraft approved material.

One correction....



The items that you should feel comfortable locally grounding are

the NON-noise-producers.  The noisy items you'll definitely

want to pull back to a central ground point.  Things like

a pitot heater though are generally not noisy, so many builders

will do local grounds for nav lights, pitots, and things like that.

I'd recommend going CENTRAL ground for HID's and devices that

have any "frequency" to the power.

Jesse,  

   

Are you referring to the SA-9900 product from Stein on the accessories page when you say “grounding tabs”?  http://www.steinair.com/accessories.htm  

   

Thanks for you input!

Ben,  

   

The grounding tabs that Stein sells seem to work quite well riveted to the structure with no paint between.  The strobes I ground very close to the battery-airframe ground, the nav lights in the wings, landing lights and pitot heat I ground locally.  Everything in the panel gets grounded to the firewall.  The lights in the tail I run grounds back to the battery ground area.  The headset jacks I do not ground, but use the fiber washers to keep them isolated from ground.  Everything from the stick grip(s) I ground under the copilot seat, although most of those grounds are just grounding the switch so when it is pushed it connects that circuit to ground to tell the things to do it’s thing.

 Subject: grounding question  

  

   

What are people doing for ground wires for the nav, landing, and pitot heat?  Are you running separate wires for ground or grounding locally to the airframe?  This might be somewhat of a “primer war” question as I’ve heard some say always run ground wires and others say ground locally.  Aeroelectric says local ground for “non-noisy” items is fine.  Just wondering what others have done.  

   

If airframe what kind of hardware do you use to get a solid ground connection?  Do you use regular AN nuts bolts and washers or do you use something like a lock washer that has more bite maybe?  Do you cover the nut/bolt with anything to slow any corrosion being that you need to clean the primer off the metal at the point of contact?  

   

Yes John I’ll wipe the dust off the 43.13 J

 Subject: grounding question  

  

   

What are people doing for ground wires for the nav, landing, and pitot heat?  Are you running separate wires for ground or grounding locally to the airframe?  This might be somewhat of a “primer war” question as I’ve heard some say always run ground wires and others say ground locally.  Aeroelectric says local ground for “non-noisy” items is fine.  Just wondering what others have done.  

   

If airframe what kind of hardware do you use to get a solid ground connection?  Do you use regular AN nuts bolts and washers or do you use something like a lock washer that has more bite maybe?  Do you cover the nut/bolt with anything to slow any corrosion being that you need to clean the primer off the metal at the point of contact?  

   

Yes John I’ll wipe the dust off the 43.13 J
