Narrative:
Aircraft xyz had a nose gear that would not come down on first attempt. I had a mechanic change nose gear bungee cylinder. After the job was done and all operations checks, leak check and gear swings had been accomplished and verified by required inspection item inspector, I signed the write-up off. On dec/xa/99, aircraft xyz had to use alternate gear extension to get nose gear down. Upon inspection, found a tool used to change the bungee cylinder stuck in gear well.
