Fixing a Grumman Fuel Tank Leak
or
How I Spent My Summer Vacation

Day 8

Done at last. Finished. Completed. Signed off.

A note about signing off a job like this: be sure to document the manufacturer, part number, batch number, and manufacture date of the sealants used. It doesn't take long, and the cost of the ink will be well worth it should an AD come along affecting certain batches of sealant. A comprehensive maintenance record entry will be invaluable if it shows that the batch you used was not affected.

Now the only thing was to go fly. Being the paranoid individual I am, we refrained from using the left tank for critical phases of flight for the first few hours, and I pulled the fuel filter after about 10 hours to see if there was any crud coming out of the tank. There wasn't.

A clean airplane and, more importantly, a dry hanger floor.
No parts left over. At least none that shouldn't be left over.
Repair? What repair?
That's all there is. There is no more.
