Posted: Mon Apr 13, 2009 4:37 pm Post subject: Door Closed switches

Well here’s another one for the books.  My airpath compass is located on the extreme left side of the panel.  I spent almost 4 hrs on the weekend trying to get the compass and GRT magnetic heading aligned.  N-S was ok, but there was 30-35 degrees difference at E-W between the GRT Heading and compass.  Drove me nuts.  Finally confirmed the error was in the compass by creating my own compass rose on the hardstand.  

   

The problem was the magnet in the door pin!  There is probably less than 12” from the magnet to the compass, but they are strong little suckers.  So, went and ordered a SIRS compass to mount on the windshield brace.  I slept on it overnight and realised that my Trutrak VSGV control head has an internal magnetometer and also might be in the interference zone of the door magnet.  

   

Simplest solution is to get rid of the door magnet and use a microswitch instead of the read relay.  Does anyone have any designs/installation instructions??  

   

Cheers,  

Ron

yes, mechanical things fail. After checking with one of the  first to lose a door I decided not to install the light system. He said that the  first time he lost the door  there was no system; but the second time he  lost the door the system was installed and he missed it. I just check the pins  physically at engine start and before takeoff. Of course I can reach the pins  and feel them in place; some have coverings there that make that sort of check  difficult.

also the three fatal crashes of RV10s did not involve an  unclosed door. You note that the NTSB report confirms doors found in the crash  site. I specifically asked the question of the NTSB investigator for 210HM. The  only door opening that came close to a fatal was 415EC? (IIRC) and it may have  had some other damage prior to door separation.

Guys,  

   

I was not looking for a debate on whether I should have a door ajar annunciator or not.  I decided long ago that I would have such a warning.  I am days from first flight and have NO interest in removing the capability.  The reed relay solution is entirely appropriate and should not be subject to many (if any) mechanical failure modes.   I just should have thought a bit more about the magnets relative to the more sensitive instruments in the panel and have posted so that others who CHOOSE to go down this path do not make the same mistake.  To my knowledge, the magnets/reed relay/annunciator are a standard inclusion in the kit these days.

FWIW, I have had a door open on me in flight because my knee hit handle and the lock pin was not completely nested in the slot at the base of the handle.  I have since installed a leather strap to the main gear base that loops around the door handle.  The door pins are not enough in themselves (IHMO), and the lights don't make any difference in the situation that happened to me.  The door pins had been in place and fully engaged.

Yes, the door pins were fully engaged, BUT a complete check would have ensured the roll pins were in the detents and that would have prevented the doors latch from moving in flight.  My roll pins nest so securely that I have to intentionally try to release them to make the handle move. 

The mechanism is good but the pilot must ensure proper latching.  You would still get green lights even with in-nested roll pins. No protection method eliminates the need for the pilot to verify secure "doors closed and latched" and I recommend that ONLY the pilot latch the doors....regardless of pin type or warning mechanism or safety strap.

Tim, being a pilot rather than a â€œpassengerâ€ sounds like the best approach.Â  Itâ€™s much like only trusting a pump and a clock to track your fuel levelâ€¦and not a fuel gauge.

Ron,

     this very problem was  brought up to me a few weeks ago by another builder, and what we decided to do  is make some door guide pins up without magnets for the front of the doors.  They will be available within the next few days. what I've decided to do is  offer to swap out non-magnetic for the magnetic pins at no cost  to any who already own the guide pin-block set regardless where they were  purchased. There also will be the option to order new kits with non  magnetic front pins added to the website soon. if any want to take advantage of  this offer be sure to drop me an e-mail before you send the old pins to me so I  can write them up with return addresses.

Another possibility is to keep the existing system and use some magnetic shielding material to keep the mag field localized to the door sensors.  There are probably a lot of sources but here’s one: http://www.aircraftspruce.com/catalog/elpages/edmomumetal.php

Ron,  

    

    this very problem was brought up to me a few weeks ago by another builder, and what we decided to do is make some door guide pins up without magnets for the front of the doors. They will be available within the next few days. what I've decided to do is offer to swap out non-magnetic for the magnetic pins at no cost to any who already own the guide pin-block set regardless where they were purchased. There also will be the option to order new kits with non magnetic front pins added to the website soon. if any want to take advantage of this offer be sure to drop me an e-mail before you send the old pins to me so I can write them up with return addresses.

Well here’s another one for the books.  My airpath compass is located on the extreme left side of the panel.  I spent almost 4 hrs on the weekend trying to get the compass and GRT magnetic heading aligned.  N-S was ok, but there was 30-35 degrees difference at E-W between the GRT Heading and compass.  Drove me nuts.  Finally confirmed the error was in the compass by creating my own compass rose on the hardstand.  

   

The problem was the magnet in the door pin!  There is probably less than 12” from the magnet to the compass, but they are strong little suckers.  So, went and ordered a SIRS compass to mount on the windshield brace.  I slept on it overnight and realised that my Trutrak VSGV control head has an internal magnetometer and also might be in the interference zone of the door magnet.  

   

Simplest solution is to get rid of the door magnet and use a microswitch instead of the read relay.  Does anyone have any designs/installation instructions??  

   

Cheers,  

Ron

Hey John,  

   

Distance between the door magnet and compass in my installation is around 10”.  YMMV, but I would not locate any avionics/instruments that are sensitive to magnetic fields within 18” of the magnets.  

   

Cheers,  

Ron

So Ron, what distance did you determine should be maintained as a minimum?

Guys,  

   

I was not looking for a debate on whether I should have a door ajar annunciator or not.  I decided long ago that I would have such a warning.  I am days from first flight and have NO interest in removing the capability.  The reed relay solution is entirely appropriate and should not be subject to many (if any) mechanical failure modes.   I just should have thought a bit more about the magnets relative to the more sensitive instruments in the panel and have posted so that others who CHOOSE to go down this path do not make the same mistake.  To my knowledge, the magnets/reed relay/annunciator are a standard inclusion in the kit these days.

also the three fatal crashes of RV10s did not involve an unclosed door. You note that the NTSB report confirms doors found in the crash site. I specifically asked the question of the NTSB investigator for 210HM. The only door opening that came close to a fatal was 415EC? (IIRC) and it may have had some other damage prior to door separation.

Ron you could also just check the door is shut

 Do you think the leather strap would hold the door shut even if the pins  were not engaged?

 I don't imagine you have tested it, but sure would like to know.

Yes, I believe that it will.  I have been informed by another RV-10 owner who has a set of these straps that it was tested (whether intentionally or otherwise I do not know) and did hold the door.  I am not about to try it myself, but I have closed the door in flight before and the force, especially when just open a couple of inches, did not appear to be nearly enough to break these straps.  Straps made out of strong webbing would likely work as well or better, but I like that the leather stretches a little bit so it can be a little tight around the handle when in place.  No matter how the doors are installed and how many steps are taken to ensure they are closed well, I still highly recommend a backup safety like this.  It gives me great peace of mind when flying, for what it's worth.  You only have to have a door come open in flight one time, for whatever reason, before really feeling the need (IMHO) for something like this.

Ron I dont have time to read all of it but I  believe Simon Pike has been doing domething with this design which is easier and  can retrofit
