FAR 21.303 and 21.305 Fabrication Of Aircraft Parts By Maintenance Personnel

Re: FAR 21.303 and 21.305 Fabrication Of Aircraft Parts By Maintenance Personnel

You better submit those rusty parts to the FAA right away to get an AD. There might be some on an airplane out there, and if yours rusted in a flood, then their's might fail under normal use. Or better, manufacture the parts for sale, then lobby the FAA for the AD.

thank you for reminding me there are a lot of folks far worse off than we here in NE Ohio. Off to get a new sump pump for next time. Did you get damage?

I am on high ground, but the shop was flooded from run off. The extent of damge was some rusty parts that were on the floor and a bunch of ruined boxes.

True BUT so many IA's think they can merely sign Block #7
( Approval for return to service) and that makes it a good 337 and many times it DOES NOT>>>> I have to sign off today and catch up tonight, WE got hit with another big rain storm and got some flooding at my home.

Flooding, what is that?(;fWe got 7" in 5 hours early sunday morning. You could not hardly drive anywhere most of sunday around central OK due to all the flooding here.

The answers come many months after the crash.
The Owner Produced Part is very interesting. Our IA seminar always has a big discussion on legally " installing" the part . They can be produced but who will install them?? HE is really sticking his neck out. I have seen a lot of block "7"s signed off by people who had no "authority" to do so ... AND NOW the 337 can be sent direct to Oak City with NO review. Trouble ahead I am sure.

From what I have been told only APPROVED DATA can be sent directly to OKC, all other 337's will still need to go FSDO for signoff. I still think BAD idea, whoever came up with this brilliant scheme.

We've been over and over this subject many times. I wish we could get a definitive answer. As always, however, what is "legal" and what is safe are two separate issues. Mike's landing gear once signed off by an IA is legal, but whether or not it has integrity depends on the ability of the IA to determine the quality of the job.

I have never seen a provision for an owner provied part....It would be an owner produced part. Your IA is taking the risk for the part if they are not the individual that repaired it or observed the repair...if they did a visual and signed off the log book as just replacing the part, then they remove the lilability for the repairs or mods, they become only lilable for the installation of a used part.....

Here we go 'round the mulberry bush... again. If the strut were constructed using the original fittings, then it would be a repair. Right? Then it could be signed off by an A&P. Right?

The following is expressed with almost a total lack of knowlege on this subject.
I believe I have presented things to my IA who has inspected/passed the item as an 'owner provided part'. Second case - I have produced a repaired landing gear of uncertain heritage. My IA, with no knowledge of the skill of whomever repaired the part, examined it and allowed me to put it on the aircraft. I believe this also fell under "owner provided part". - MikeH

They keep changing the wording to where it is hard to keep up anymore. It was located in a different section of the FAR's, maybe 43. AC 43-18 is very good reading regarding parts fabrication without approvals. I will do some more looking and report back.

I think the words "for sale" are in there somewhere...

I also think that an owner could easily make a case for the fact that Taylorcraft has been in and out of business, and able/unable to legally produce parts many times over the years. Some PMA houses have also had times of being in and out of stock on parts.

So it should not be too difficult to say "in order to insure that a needed aircraft part was available for the maintenance and continued safe operation of the aircraft, the owner had the part fabricated within the provisions of FAR 21.303 for his own aircraft, did not and does not offer this part for sale or for use on any other aircraft".

Hey Bill,

Neither the regulation nor the AC require you to make any case at all.

Maybe some FAA fellow is being stubborn but I sure don't see any requirement about parts not being readily available in any of the text.
