Changing Radio

[4RJN]

I have a 2006 ctsw SLSA plane and the radio may be bad although no one has chimed in with thoughts on it. Anyways can the King KY97A radio be removed and replaced by say an ICOM A220 TSO radio or is this not an approved change to keep it a legal SLSA? 

Thanks

Must be MRA'd. Any alteration has to have one, regardless if they ship with those parts as an option and you chose something else.

The process for the procedure is pretty easy. Fill out the MRA request form and submit it to Airtime Aviation. Be advised that there will be a fee to process the request. All this is because ASTM requires the manufacture to track any changes to the aircraft.

Thanks for the reply I really appreciate it. If I decide to go that route I will be sure to get in touch with Airtime Aviation. Best Wishes and Thanks again, Rod

Just wondering if you know about how much it will cost get the MRA? Thanks

I went with Garmin GTR 200, great radio.

I think $75, but you need to check with them to make sure. We went with the Garmin GTR200 in another airplane, and are pleased with it.

Hi Tom, did they issue a fleet wide MRA for that radio? Is the Garmin approved for SLSA? Thanks

Hi Madhatter, is your plane an SLSA? If so how did the process go for you getting the MRA?

MRAs are only $75 when no engineering has to be done. MRAs are really simple. Just ask Airtime Aviation for the form.

Madhatter is E-LSA

I have been ELSA for years, best thing I ever did. I can make legitimate changes and installations with a logbook entry, even easier than certified. ELSA doesn't mean substandard maintenance or installs like some think. There is plenty of poor quality maintenance out there no matter what the type of certification category aircraft you have.

The engineering has already been done, so the process is easy. It is my understanding that ASTM requires the aircraft manufacture to record all changes to the airplane from date of manufacture, and verify that changes meet ASTM standards. The MRA is the process by which Flight Design complies with this requirement. The fee is for completing the paperwork.
