Narrative:

On our previous flight the GPS failed. On the completion of that flight I wrote it up. Just prior to our flight the director of maintenance came to me with the write-up explaining what he did to correct it. Trusting his skills as a mechanic and director of maintenance I did not feel it was necessary to doubt him and to double check his work. This proved to be a mistake in that it was incorrectly documented and I fear that it could have been something more serious. Everyone makes mistakes no matter how good they are. The error was discovered when I got one of the other mechanics in the company to follow up on it. I flew an aircraft that was illegal because of improper documentation. I flew an illegal aircraft because I failed to double check to ensure the documentation was correct. Don't trust anyone.

JUST PRIOR TO OUR FLT THE DIRECTOR OF MAINT CAME TO ME WITH THE WRITE-UP EXPLAINING WHAT HE DID TO CORRECT IT. TRUSTING HIS SKILLS AS A MECH AND DIRECTOR OF MAINT I DID NOT FEEL IT WAS NECESSARY TO DOUBT HIM AND TO DOUBLE CHK HIS WORK. THIS PROVED TO BE A MISTAKE IN THAT IT WAS INCORRECTLY DOCUMENTED AND I FEAR THAT IT COULD HAVE BEEN SOMETHING MORE SERIOUS. EVERYONE MAKES MISTAKES NO MATTER HOW GOOD THEY ARE. THE ERROR WAS DISCOVERED WHEN I GOT ONE OF THE OTHER MECHS IN THE COMPANY TO FOLLOW UP ON IT. I FLEW AN ACFT THAT WAS ILLEGAL BECAUSE OF IMPROPER DOCUMENTATION. I FLEW AN ILLEGAL ACFT BECAUSE I FAILED TO DOUBLE CHK TO ENSURE THE DOCUMENTATION WAS CORRECT. DON'T TRUST ANYONE.
