I just sold my aluminum heater vent box that goes on the firewall, because I had heard that one of our builders here in Ottawa was snagged for not having a stainless steel one. This brought a question from Rick at VAF as to what he should do in order to satisfy MDRA requirements. He has not been able to reach them yet.
I replied to him with the info posted below, and he suggested that this should be posted on the forums.
I'm therefore posting here what I know, some first hand knowledge as well as heresay. Hopefully other Canadians can chime in with their experience, as this would certainly help new builders. Please correct me if I am wrong. Would be really really nice if this information was already on the MDRA site, no?
[actually a checklist does exist, but lacks some details in certain areas .... http://www.md-ra.com/pdfs/what_inspectors_ck.zip More detail and applicability to the RV series would be nice]

Here's some things I've heard from MDRA inspector, or from other people that were inspected by MDRA.
P.S. I have already had my precover inspection in 2005, and had no snags. I want to be well prepared for my final inspection (hopefully this summer), so am looking to draw up a detailed list that would benefit everyone.

Here's some things I've heard from MDRA inspector, or from other people that were inspected by MDRA.
- Baggage floor must either be removable, or have access hatches so area can be inspected for damage or corrosion (conversation with inspector in 2002)
- Gascolator is required by MDRA (conversation with inspector). I'm not sure if this is a requirement, but I've extended the drain so I can drain daily.
- Any part that rotates, must have a bolt with castle-ated nut and cotter pin (elevators, rudder, control sticks etc.). This was flagged as a snag by an inspector recently.
- Pre-cover inspection for fuel tanks must have the rivet shop heads visible. Only after inspection can you cover them with proseal. From conversation with inspector in 2002 and 2005.
- Local builder here was snagged for the aluminum air box. His fix will be to replace just the flap with stainless
- Wiring must all be aircraft grade (Tefzel or such). Some builders I know used PVC insulated wires for their projects just a couple of years ago .. no more.
- I heard that some MDRA inspectors were giving some builders a hassle regarding halon fire extinguishers [this was back in 2005, I think]. I believe this is cleared up now, since the inspector had misinterpreted a Transport advisory letter. Can anyone comment? I plan to use halon, and will certainly push this point.
- Fire extinguisher on-board is a requirement. Not sure, but I would believe that 2 lbs is adequate amount.
- No nylocs fwfwd, only metal nuts.
- Electrical wires must be routed over (not under) fuel lines. My rule, but I heard this through the grapevine (and AC43).
P.S. I have already had my precover inspection in 2005, and had no snags. I want to be well prepared for my final inspection (hopefully this summer), so am looking to draw up a detailed list that would benefit everyone.
