Narrative:

I flew my aircraft with no current weight and balance from linden, nj, to lincoln park airport (avionics shop) for GPS installation. GPS was installed and 337 form was given to me to carry to FAA office (FSDO-25 teterboro, nj) to be signed by airworthiness inspector. 337 form was not signed, the aircraft which I flew from lincoln to teb was not airworthy due to 337 form was not signed and I flew aircraft. The same day we corrected weight and balance and I have a new correct weight and balance. I flew the aircraft to linden airport on the ferry permit issued by teb FSDO-25. Next day, I bring the new weight and balance and 337 form to office FSDO-25 where I am working as an operations inspector (air carrier) which was stamped and approved by FAA and checked by supervisor. He agreed that everything is ok but because I flew aircraft without correct weight and balance, they have to follow up and file violation. I didn't know that my weight and balance was not correct and I wasn't told by avionics technician that I couldn't take the aircraft if 337 form is not signed.
