Narrative:
Gate mechanic reported to me that left main landing gear bonding wire broken from inner door to strut. I ordered part from stock room. Later, ground bonding wire came, but it was too short. Reordered new one, same length came. Rechked ipc and reordered third wire. During waiting for new wire, I discussed with gate mechanic to connect 2 wires together and deferral. I asked 2 a&P's to help out, and called maintenance control for information. While speaking to maintenance control for 10 mins on the telephone, he told me that per gnmm we can connect 2 wires together and defer with engineering variation approval. During conversation with maintenance control, I heard on radio one mechanic said that we've got it and ready to go. I thought they got the right ground bonding wire so I told maintenance control we got the right ones. I went back to my office. 1 hour later, I found out gate mechanic deferred these ground bonding wires without engineer approval (no engineering variation approval). Aircraft revisited 3 1/2 hours later. We cleared that deferral with the right length ground bonding wire.

Title: A B737-300 WAS DISPATCHED WITH AN INTERIM REPAIR MADE TO THE L MAIN LNDG GEAR INNER DOOR BONDING WIRE WITH NO ENGINEERING APPROVAL OR REPAIR DOCUMENTATION.
Narrative: GATE MECH RPTED TO ME THAT L MAIN LNDG GEAR BONDING WIRE BROKEN FROM INNER DOOR TO STRUT. I ORDERED PART FROM STOCK ROOM. LATER, GND BONDING WIRE CAME, BUT IT WAS TOO SHORT. REORDERED NEW ONE, SAME LENGTH CAME. RECHKED IPC AND REORDERED THIRD WIRE. DURING WAITING FOR NEW WIRE, I DISCUSSED WITH GATE MECH TO CONNECT 2 WIRES TOGETHER AND DEFERRAL. I ASKED 2 A&P'S TO HELP OUT, AND CALLED MAINT CTL FOR INFO. WHILE SPEAKING TO MAINT CTL FOR 10 MINS ON THE TELEPHONE, HE TOLD ME THAT PER GNMM WE CAN CONNECT 2 WIRES TOGETHER AND DEFER WITH ENGINEERING VARIATION APPROVAL. DURING CONVERSATION WITH MAINT CTL, I HEARD ON RADIO ONE MECH SAID THAT WE'VE GOT IT AND READY TO GO. I THOUGHT THEY GOT THE RIGHT GND BONDING WIRE SO I TOLD MAINT CTL WE GOT THE RIGHT ONES. I WENT BACK TO MY OFFICE. 1 HR LATER, I FOUND OUT GATE MECH DEFERRED THESE GND BONDING WIRES WITHOUT ENGINEER APPROVAL (NO ENGINEERING VARIATION APPROVAL). ACFT REVISITED 3 1/2 HRS LATER. WE CLRED THAT DEFERRAL WITH THE RIGHT LENGTH GND BONDING WIRE.
