LGT MECH FORGETS TO REMOVE NOSE GEAR ANTI-RETRACTION PIN.

Narrative

ACFT RECEIVED A RED LIGHT ON THE NOSE GEAR ON TKOF RETRACTION. I AM AN AIRLINE LEAD MECH. I HAD RELEASED THE ACFT 1 HR PRIOR TO THIS TKOF WHICH REQUIRED AN AIR TURN- BACK AND DELAY. THE LIGHT WAS BECAUSE I HAD FAILED TO REMOVE THE NOSE GEAR ANTI-RETRACTION PIN. THIS WAS A LOGBOOK ENTRY AND I DID SIGN FOR REMOVING ALL THE GEAR PINS. THE MAIN GEAR PINS WERE CLRLY VISIBLE AND I REMOVED THEM. IDENTING THE NOSE GEAR PIN WAS DIFFICULT FOR ITS STANDARD 'REMOVE BEFORE FLT' STREAMER WAS NOT VISIBLE. WITH A MAINT CREW OF 5 OR 6 MECHS AND AN ACFT GOING OUT IT IS NOT UNCOMMON TO GET CAUGHT UP IN THINKING MAYBE SOMEONE GOT IT AND FORGOT TO SIGN FOR IT. I DID LOOK IN THE NOSE GEAR SECTION VERY HASTILY AND VERIFIED THAT THERE WERE PINS IN THE POUCH. ALL IN ALL IT WAS MY NEGLIGENCE THAT CAUSED THIS INCIDENT AND I DID RECEIVE A DAY OFF OF WORK WITHOUT PAY FOR IT. BECAUSE IT WAS NOT A SAFETY RELATED ITEM TO THE ACFT; MORE OF AN INCONVENIENCE TO THE FLC AND PAX. I STILL BELIEVE IT IS NECESSARY TO RPT MY FAULT DUE TO THE AIR TURN-BACK
