Here is an excerpt from an email I received yesterday...

Hello ray,

After further review, Transport Canada has no objection that you continue operating aircraft registered C-GJRL in the present ...

Glad to help. I think it is almost over.

Some things are too silly to live. This was one of them.

I just sent my (latest) reply off to the DOT inspector. I found ST02156AK which is an STC for supercubs. It allows for the installation of an underseat sealed battery (Odyssey) to replace the origina ...

Hi Bob

You might find this amusing. It is an excerpt of a message from the DOT inspector where he cherry picks words from the Power Sonic manual. The underlines are his.

Given the right set of c ...

To answer Raymond's question:
An MDRA inspector is not a civil servant. He is a volunteer. In my case he is also an AME whose livelihood depends on keeping this same DOT inspector happy.

I have no ...

Thanks for the references guys.
I believe there are some AGM batteries that have a 'vent' port designed to connect to a vent tube from an existing flooded cell battery box. The 'sealed' models with ...

Thanks to all have responded. From communications with the DOT inspector, it is clear that the quickest solution will be to reference a STC for a cub or similar that uses an underseat strap down of a ...

MDRA is only involved in the building process. I had an engine failure at a controlled airport. That got DOT’s attention (that’s fair). The cause was from radiant heat cooking my fuel pumps (They ...

Thanks for your help so far.

Let me give more background. The aircraft has been flying for over 3 years. The MDRA inspector was fine with the battery.

My aircraft has been grounded since the ins ...

An STC of an equivalent installation might be the easiest way to convince. I think that would be an unvented AGM inside the cabin. I see there are some under seat Cub STC's that might do. Does anyone ...

Here are his words...
"you have not provided specific "accepted aviation standard practices" references or documentation required to meet Canadian Aviation Regulation Standard 549.5(b ...

Help. I have a homebuilt CH701. A DOT Inspector (Canada) is trying to force me to retrofit a battery box on my sealed Power Sonic battery attached to the cockpit side of the firewall. I need to conv ...

Now I'm puzzled. I see the statement in the 601 faq but I cannot find it mentioned in the CARS. You must do a fuel flow test in climb attitude though, which is probably more relevant.

FWIW my fuel ...

I think most of what your are looking for is in Appendix A of “EXEMPTION FROM SECTION 549.01 … - AMATEUR-BUILT AIRCRAFT”. The appendix calls out:
i) a fuel quantity indicating system for each m ...

This is the 2nd winter for my 701. Last winter, in heavy snowfalls the tail would drop. I put a couple of tires just in front of the tail hook for it to plop onto.

This year I drove a couple of p ...

I was surprised too. I can only assume it was builder error. Perhaps I should have lowered the pressure on my rivet gun.??

I have the doors too. I believe they use extruded polyester. I forget the brand name. It appears to be available in Europe but I could not find it available on this continent. It has properties very ...

One brand is "Flame Stopper 5000® Intumescent Sealant". It is sold by Ace Hardware among others.

I used GE Firestop Intumescent Sealant. I learned what intumescent was when looking to seal wiring going through the firewall. This stuff is designed for through cable penetrations. It expands when he ...

That is how I did it. I had a Canadian inspector instead of FAA, and he did not bat an eye. In my case the battery is in cabin, up against the firewall, in front of the passenger.
