Re: TSO requirements

I just happened to be at an operators place when TC showed up to do an audit, I took the opportunity to ask these questions. I agree that the stumbling block would be getting a shop or AME to install the non TSO's comm. I would bet anything that once it was installed 90% of AME's would probably sign...

Re: TSO requirements

They said that when I mentioned that EAA has an STC to allow Dynon non TSO'd EFIS screens in certified a/c ( C172's etc) then they said " well that doesn't mean you can do that in Canada, we don't recognize all FAA STC's"

Re: TSO requirements

Well at first they said no, it has to be TSO'd as per the original certification then when I said the 140 was certified without a radio then they said it would need a STC for any install. When I brought up the amateur build argument they had no explanation. To end it without actually going on the re...

Re: TSO requirements

Everything that Heliian is saying about unapproved PARTS, I completely agree with. I would not want a control cable, bell crank, etc that are critical to flight to be made in someones basement. That goes for an ELT or Nav radio as well, again something that could kill me. But a VHF comm? I'm with a ...

Re: TSO requirements

"the equipment must provide the same level of safety as that established by the certification basis of the aircraft.” Yes, I seen that....not that I understand what that actually means. Especially when in regards to a C140 for example that was certified in 1946, there would have been no radio even m...

Re: TSO requirements

Bingspot,

I suppose the problem might come up if the AME won't sign the annual if he sees it is a non TSO radio.

Re: TSO requirements

photofly,

everything you say makes sense, but then why are non certificated aircraft (experimental) allowed to fly in the same airspace as everyone else with non TSO'd radios?

Re: TSO requirements

Ok, thanks for that. I guess there is no way around it then even though there are many non TSO comms( Flightline) that have very good functionality and great reviews from owners. I see that there has been some movement in the non TSO EFIS area, DYNON has an STC to be able to install their EFIS scree...

TSO requirements

Hi guys, Can anyone point me to where in CARS it actually says that a comm radio needs to be TSO'd in a VFR airplane. I have found references in places that point toward FAA rules, but I get lost pretty quick in the CARS. In some places in the FAA world they refer to a/c that were certified under CA...
