337 Oxygen Leak

[Bob Cook]

There are numerous methods of detecting a leak.
one method ::
small charge of freon and use a freon detector... very sensitive.
be sure to purge the system using a vacuum then recharge with oxygen after the leak is found.

Is this the large tanks in the overhead? If so then why not consider a small bottle like skyox which is cheaper to fill, easy to certify and far less weight. The overhead oxygen system with dual tanks must be robbing you of at least 100 lbs of payload. I can look it up if you like or look at the original equipement list.

You may need to get these tanks properly pressure tested as I would question putting 2500 psi to them without doing so. They can be very good missiles when they blow....... think less than every 10 yrs. they do a under water static test and no doubt will find your leak if it is in the tank..

Probably came out of a 747 <G>. like to fly those "7's" ??
