References for Owner produced parts

[moodychief]

Recently I was having trouble locating a prop cable for my 63 C model.  I was told by several folks to have a place in Kansas (that makes approved cables for aircraft other than Mooney) make the new cable for me.  I asked if that was legal and each one hemmed and hawed at an answer.  Wanting to be perfectly legal I called the local FSDO to see what guidance they could lend.  Believe it or not, the FAA is here to help and they provided me the information in the text of the email below.  I thought I would share in case anyone is going through the same issues.  

 

Charles: 

 I have accomplished some additional research concerning your question about a replacement engine control cable for your Mooney: 

Yes you can have a part manufactured and classify it as an "owner produced part"  as identified in FAR 21.9 (a)(5), which is attached. 

There is a process that must be followed and it is identified in Advisory Circular 20-62E which is attached.  Its not very difficult or hard to comply with. (see Advisory Circular 20-62E, paragraph 4(n)) 

You stated to me during our conversation that you were aware of a manufacturing facility that produces similar cables for other makes of general aviation aircraft. 

I believe you will be well within regulatory compliance with the requirements for an "owner produced" part if you complied with the following list of actions: 

a)  You are the legal owner of the aircraft. 

 You remove the cable from your aircraft to be used as a sample to manufacturer a new cable. 

c) Provide the cable the cable manufacturer you referenced in our conversation as a sample for the manufacture of a new cable.  (Providing the manufacturer of the cable to use as a sample would satisfy the owners participation responsibility of Advisory Circular 20-62E). 

d)  Install the new cable in your aircraft by a person authorized to approve the aircraft for return to service after the installation.  The maintenance log entry for the new cable should indicate that the cable installed is an owner produce part in accordance with FAR 21.9. 

We believe if you follow the above guidance, you will have complied with all of the FAA regulatory requirements to classify the new cable as an "owner produced part".  Additionally having the cable manufactured by a manufacturer  who is experienced in manufacturing similar cables for other type certificated aircraft will assure your aircraft is returned to service in a condition that is equal or better than its original condition (FAR 43.13)
