Mounted my fire extinguisher - finally!

[Heybluez]

First 'upgrade' of the year! Firgured it beats it rolling around the back seat looks like a good place.. the seats don't touch it even when all the way back. I think it will also be out of the way for  passengers even though I've not been able to test that.

There is a manufactureres service bulletin calling for replacement of those cabin extinguishers for one with a pressure gauge.

I like this. I need one. Is that a Halon?

[gsxrpilot]

Yeah, I need one as well. Is there a size on it? What size should I be looking for?

Would you happen to have a picture?

[carusoam]

Reminder, no accidental drilling of the expensive spar parts.

know what is there before drilling.

This reminder is for the next guy, that may miss an important detail.

Best regards,

Looks great. How did you attach the mounting bracket?

I unscrewed the plastic back seat top, then unscrewed and removed the carpet piece that is covering the metal frame. The carpet is the one with the levers that move the seats. It is supported by a plastic backing.  I measured where the bracket should be, then drilling through the plastic backing with a drill bit big enough for a #8 stainless steel screw. I then used two washers, a screw and nut (each) to fasten the bracket to the carpet piece. I even put some teflon anti chafing tape over the nuts in the back just in case it touched the metal when put back on but it doesn't seem to touch anyway.  Then I reassembled it all.

NO DRILLING INTO ANY STRUCTURE!

Yikes. I did no drilling on the plane itself! See description.. removed the carpet piece... nothing on the structure of the plane.  No way I'd be that "brave" to go sticking a drill where it doesn't belong!

You'll likely need to remove the extinguisher before attempting to remove the front seats. I have articulating seats in my K Model and they slide almost all the way back before releasing. Here's an alternative location I found. Very handy.

[carusoam]

That surely defines 'close at hand'

Being that ready will keep the opportunity to use it at bay...

Only you "electrified" guys can do that with an arm rest! Us charlie armstrong gear guys are left out but then again, we don't have no stinkin' gear actuator problems :-) :-) :-)

I have mine installed in the pilot side foot well. Easy quick access with no interference. Easy install, just three ty-wraps to the tubing structure

I can't imagine that Ty wraps would meet the strength requirements to hold it in place?

From AC20-42D,

(I) Aircraft structure and mounting brackets are required to withstand the applicable inertia forces required in 14 CFR §§ 23561 , 25561 , 27.561 , and 29.561, with the hand fire extinguisher installed. Replacement of halon extinguishers with halocarbon extinguishers will require an evaluation ofthe mounting system strength. The mounting structure may need to be strengthened. Halocarbon clean agent extinguishers of the same listing can be 2-3 times the weight of the halon extinguishers they arc replacing.

But you have no problem with the OP screwing it into a plastic panel? There is no way to install a mount with structural integrity without involving the FAA, DERs, far too much paperwork and lots of time and money. Which is stupid . . . Safety shouldn't be difficult and expensive.

The important thing with a fire extinguisher is having one, and being able to grab it when needed. Nothing else matters, but it is nice if it's not in the way while waiting years and years for the opportunity to use it in anger.

[bonal]

Got a small basket that sits behind pilots seat for incidentals and the extinguier sits down in it and stays put. If needed I can reach between the seats and it's right there.

I had to go back and re-read the post, it too is not installed correctly per the AC.  For those installing them with Ty wraps or mounted to plastic, it would suck to die because it jambed your controls or knocked you unconscious in turbulence.

Some Mooneys have the extinguisher factory mounted to the main spar, my mistake for assuming the OP copied that method.

Clarence

[bonal]

As a fair weather VFR guy I've never experienced turbulence that could get my extinguier out of its spot and really what would be a bigger issue is all the tools and what's it's behind the back seat

Do not underestimate the ty-wraps strength for this application.

Typical ty-wrap tensile strength is 50 pounds http://www.southerntennissupplies.com/heavy-duty-ty-wraps-8-120lb-break-strength-bag-of-100/

Fire extinguisher weight is 3 pounds http://www.aircraftspruce.com/catalog/pspages/a344t.php?clickkey=3009258

Under 3 gs it will be 9 pounds.

Net weight force of 9 pounds per Ty-wrap is 3 pounds

So the ty-wraps will be barely 6% loaded of their ultimate breaking point.

Not bad for ty-wrap mounting.

I wouldn't sign the annual if it showed up in my shop held on that way.

Don't worry I wouldn't trust you for my annual.

Never mind the piss!ng match. What is an approved way to mount an extinguisher in a Mooney that left the factory without one? How about in a short body Mooney that can't put one in front of the back seat and still permit the pilot to get in and out? Can't screw it into anything structural, and you seem to not like the two non-structural mounts here. Guess we should get oval extinguishers and out them in the seatback pockets??? 

[gsxrpilot]

I'm liking the tie-wrap mount even better after the previous few posts. It's easy to remove at annual time and then reinstall after. Tie-wraps are cheap and quick.

[takair]

Perhaps Adel clamps in place of the tie wrap would be a compromise.  I think in my case my knee ends up in that area.  For a while, I had it mounted to the seat adjust bar.  Great location, but in one case it rotated and the seat did not lock completely, and I was also worried about it releasing the seat in severe turbulence.  Still looking for an optimal location in a johnson bar airplane.
