logging and building time

[velocity dreamer]

How do you go about logging your build time. whats required for airworthyness inspection by the FAA. whats included in the times? is it the time taken to lay up the part or the time taken to lay up and cure. If it says 500 hours to build could you say 10-20% of that is cure time for the fiberglass. Also does the hours and hours behind this computer reading post count. haha.

You write down whatever you like.

Nothing. The FAA couldn't care less how much time you spent building your plane.

Since the FAA doesn't care, you can write down anything you like, and claim as much or as little time for whatever you do.

Sure, and write down the times you spent eating lunch while staring at the plans, too.

 

The only thing the FAA cares about is whether it was built for "education and recreation", that the "majority" of the aircraft was built by the builder(s), and if you want the "Repairman's Certificate", that you can show that you were one of the builders and are intimately familiar with the aircraft.

 

Feel free to log anything you like.

Build time is a useful metric to determine how done you are, so it's important to get in-sync with what the manufacturer/publisher advertises as their "time to complete". Generally speaking, build time is hands-on work where you're getting dusty, dirty, or sticky.

 

I have a full write-up titled Building Time Defined on my Web site, FWIW.

As with most things FAAoid, the final decision is up to the inspector/DAR.

 

It would be a good idea to get in touch with the inspector that you will be using, assuming he/she is still alive after the build, and ask him/her what he/she would like to see as substantiation of your build. At a bare minimum, a photo album of your work.

 

Don't forget that the more information you give, the less of a hard time you can be given.

 

Additionally, make sure that all of your paperwork is complete and completed properly.

 

Good luck
