Now I ask you just what is wrong with this picture! First we have an FAA inspector who sees a leak and then he reports it. Then aircraft maintenance personnel say they did not see any leak only to find out two weeks later the leak was just were the inspector had stated it was. My question is why didn’t the FAA inspector just insist the plane be grounded until the leak was fixed?
JIMC says: First. The inspector doesn't have the authority to ground the aircraft.
JIMC says: Last. even if there was a fuel leak there was no danger to the aircraft.

That may be true, however one phone call to the FAA could change that in an instant since the FAA can and does ground aircraft on occassion. American Airlines crash in Chicago comes to mind when they grounded all DC-10's. So do not say it cannot be done it is clear they can
That was in response to an incident that cost lives and they grounded all aircraft of that type until the cause of the accident was discovered. This aircraft was just suspected of having a fuel leak and there was no incident.
Obvously the FAA thinks different then you do or they would not have filed a claim against them, would they?
What I find interesting is that this is a lawsuit filed against American Airlines by a Federal prosecutor from Brooklyn New York. The article states that there was a supposed violation of FAA regulations. The interesting part of this is if the FAR's (Federal Aviation Regulations) were violated then why isn't this being handled as a regulatory hearing by the FAA as is the usual procedure. The FAA is quite capable of investigating this and if necessary imposing fines and penalties.
Also as you noted Flight 800 and its theory if true could also prove your theory wrong as to no danger to the aircraft.
The stated cause of the Flight 800 explosion has nothing to do with a fuel leak. It has to do with fuel vapors being ignighted by the wiring in an empty fuel cell. There are enough holes in this theory to drive a truck through. One of them is. The jet fuel used was JET A it has a flashpoint of 120 degrees F. The flashpoint is a temperature at which a material gives off flamable vapors. How did the internal temperature in that cell reach 120 degrees? The second is that the JET A vapors are heavier than air. Remember the venting system I talked about earlier? If the temperature was warm enough that the JET A was giving off vapors then the vapors should have displaced the air in the tank causing the air to leave through the vents. This should not have allowed enough oxygen to be in the tanks to cause an explosion. Remember the grade school science experiment where you place a candle in the bottom of a beaker and light it. Then you mix vinegar and baking soda in another beaker and you dump the CO2 into the beaker with the candle and the candle goes out. Same thing.

JIMC sorry but I will not buy your arguments at all. The fact is that jet fuel can and will burn given the right conditions that is a fact.
Now that we know it can burn that only means one thing it can endanger an aircraft. Get back to me when you can prove jet fuel will not burn OK?

You've got it! You said it yourself,"jet fuel will burn given the right conditions" until those conditions are met a minor fuel leak is not a danger to the aircraft.

And What happens if the small leak ruptures and turns into a big leak? OOOOPs plane runs out of fuel if over a large body open water, runs out of fuel and bye bye plane and passengers.

Second. How does he know it was a fuel leak? There are other fluids inside that wing besides fuel. Where do you think the water in the restroom comes from.

Third. Aircraft leak. It is just a fact of life. A fuel leak is not cause for the grounding of an aircraft.... This leak may just have been some fuel or other fluid releasing from a vent to equalize the pressure.

If the man was a maintenance inspector he wouldn't have had to say anything to the flight crew about the leak. He would have either recognized it for what it was or he would have made a simple phone call to his office and got the number for American's head of maintenance and let him know about it.

Last. even if there was a fuel leak there was no danger to the aircraft. Jet fuel is very hard to ignite. It may surprise you to know that both military and civilian aircraft actually dump fuel from their tanks while they are in the air. The civilian aircraft don't do it except in case of emergency, but military aircraft do it all of the time. Next time you watch the movie "Top Gun" watch for the scene where the Tomcat is chasing the A-4 and you see the white vapor curling up around the back of the Tomcat. That vapor is the dumped fuel. The movie "Die Hard 2" where he lights the leaking fuel on the ground and blows up the plane is impossible. If you dump a bucket of jet fuel on a fire all you are going to do is to put the fire out. Wait a few minutes and try to light the vapors coming off of the hot coals then you will get your BOOM! I do not buy into the fuel vapor theory that is used to explain the explosion of the 747 off of New York a few years back, but that is something for another thread.

Chances of that are very remote. As far as the plane running out of fuel over open water goes it is possible but again remote. Seeing as how the fuel tanks are in the wings and fuselage and knowing how they are constructed. If you had a large enough failure for the aircraft to lose all of its fuel in such a short amount of time, the loss of fuel would be the least of your worries. Fuel systems are designed as a series of tanks, not one large tank. Inside if these tanks there are structures called "slosh baffles". What slosh baffles do is to prevent the fuel from moving around inside the tank when ever the aircraft maneuvers. If it wasn't for the slosh baffles an aircraft gould tear itself apart from just the movement of its fuel.
Any kind of failure serious enough to result in the loss of all of an aircraft's fuel would be severe enough that the aircraft would crash long before the engines stopped turning. Commercial aircraft in the US are required to carry enough fuel to get to their destination plus enough to have a reserve of at least 45 minutes. With the pumps and shut-off valves in the individual fuel tanks the failure of any one tank resulting in the loss of it's fuel would be an inconvience not a catastrophe.

Incorrect; an FAA ops inspector does have the authority to ground an aircraft.
The lav water; also known as "blue juice" or "blue lagoon" is store in the fueslage--not the wing. The only fluid actually stored in the wing is fuel. Hydraulic reservoirs are typically mounted on the engines because the engines drive hydraulic pumps. However, a leaking hydraulic contol or valve could cause the fluid to deep onto the wing. But hydraulic fluid is red and it would be hard to mistake this for fuel.
Depends on where the leak is and what is causing it. I've declined an aircraft for having a fuel leaking (even small) where it shouldn't be leaking.
The "white vapor" in those scenes are either condensation trails from the engines or from the wings. When an aircraft is maneuvering the air flowing over the wing may cool to a temperature at or below the dewpoint. This will make the water vapor become visible. As a military pilot I can tell you that we do not dump fuel except, as you stated for civilian airliners, in an emergency.

The article doesn't say what type of inspector lodged the complaint.

In certain models of aircraft potable water is carried in tanks in the wing near the wing root. You don't wash your hands with the blue juice.

Exactly. You have declined an aircraft because fuel was leaking from where it shouldn't have been. You knew that it shouldn't have been leaking there and did the correct thing. The article doesn't state where the leak was, the wing is a big area. It does state that the aircraft was checked and was considered safe.

The scene that I am referring to is a fuel dump. The pilot flying the Tomcat was later assigned to VF-31 on the Forrestal and told us about the filming of Topgun. I first saw Topgun in VF-31's Ready Room. Naval aircraft operating from carriers dump fuel all of the time.

From the actual complaint:
23. In the course of the November 17, 2003 flight, a Federal
Aviation Safety Inspector (the "Inspector" or the "FAA Inspector"),
travelling aboard the aircraft, observed what he believed to be fuel
leaking from the area of a fuel access panel on the top of the right
wing of the aircraft (the "fuel leak").
An ASI has the power to ground an aircraft if he believes it's unsafe.

Please state which aircraft you are referring to. I've only flown Boeings and can tell you they keep the blue juice and the potable water in the fuselgage. The problem with storing these fluids in the wing is that they would freeze relatively quickly as the wing offers little protection from extremely cold temps.
There is no place on the wing, except perhaps a vent port, where a fuel leak in permisible. According to the quote from the complaint, the inspector "observed what he believed to be fuel leaking from the area of a fuel access panel on the top of the right wing of the aircraft (the "fuel leak")." This could just as well be condensation.
If the aircraft was "checked and was considered safe" then that would mean the pilot wrote up the leak in the maintenance forms. There's no reason for maintenance to "check" into a problem, especially a fuel leak, unless it's written up. Minor things--yes. But not a fuel leak.
You made it sound like military pilots typically, and with frequent regularity, dump fuel, which is not the case. There is no benefit to doing this. The next time I watch that silly movie (the aerial scenes were great but the drama was downright silly) I'll try to notice the scene you're talking about. Though, I'm not looking forward to another "Negative Gohst Rider the pattern is full" line!!
