To fix leaks in a planes fuel tank, you must monitor the issue carefully, identify the type of fuel tank system that you’ve, thoroughly inspect the fuel tank, take off the tank in case the problem lies within it, repair the fuel tank based on its type, and put up the repaired fuel tank back in place.
Leaks in plane gas tanks are serious issues and should be fixed instantly. Listed below are fundamental techniques that Boston air charter technicians perform for this particular type of issue:
Check out problem carefully
There are various probable causes behind a fuel tank that is leaking. The issue should be properly identified first so that you can develop a good solution. Note any necessary details you observe during inspection of the tank and also the leak.
Identify the type of gas tank system which you have
You could refer to the planes maintenance guide to learn important information about the kind of gas tank system you have. Basically there are three types of gas tanks: the integral fuel tank, the fuel cell type, and the built up type.
Meticulously check the gas tank
Review the servicing manual to learn which sections you may remove in order to access the fuel tank. Scrutinize the lower aspect of the panel during removing. You should observe if there’s a fuel smell present or if the panel is wet. Double check all cable connections and also clamps to ensure that they’re attached properly and safely.
Remove the tank if the problem lies inside
If you’re certain that the leak comes from the gas tank and not really a loose contact, you must determine if you could remove the fuel tank. The guide can provide you with facts about the elimination procedure. In case the gas tank is of the integral type then it cannot be pulled because it is developed directly into the plane. Fuel cell models can be removed by loosening each and every connection, and built up types could be taken out through removing specific panels. Typically, the airplane needs to be defueled before the gas tank is taken out.
Fix the fuel tank according to its type
Review the plane’s manual to determine the particular ways and components essential for making repairs on the fuel tank. Fixing integral type fuel tanks often involves sealing the leaking seams or rivets. The repair for fuel cells as well as built up gas tanks should be made right after leak checking using air pressure. The gas tank lines need to be capped. While executing this, use your hand to cover the filler opening and the tank will then be depressurized. A water and soap combination can be employed to locate leakages because bubbles will form when leaks are present. In case you have found out where the leak is, you could either execute the field repair yourself or send out the faulty tank to a certified repair center. To fix built up tanks, you must eliminate the sealant surrounding the leak and replace it per the vendors instructions.
Install the repaired gas tank back in place
Particular instructions for the reinstallation of fuel tanks are available in the aircraft guide. Torque the cable connections based on the guidelines. The airplane could then be refueled and inspected for any big leaks. Since little leakages may not be quickly noticed, you may need to wait about twenty four hours before setting up the leftover access panels.
