Why and how aircraft maintenance sumps fuel tanks. This is to prevent any water in the fuel system (getting into the engines), prevents/monitors for microbial growth and prevents corrosion in the tank. Also a interesting product i got to test that from www.jetfuelwash.com which worked like a charm. THIS WAS PURELY TO TEST THE PRODUCT, IM A PROFESSIONAL. Sometimes we do get drenched in fuel and its just part of the job, even with protective equipment we still get jet fuel on us time to time. If anyone has ever worked in the aviation field then you exactly how long thats Jet A smell stays. #stigaviation #fuelsump #jetfuel #jetA #jetfuelwash #aircraftmaintenance #aircrafttechnician #themoreyouknow #learnontiktok #tiktoktaughtme #jetfuelsmell #eliminateodors #handwash #itsmells #fuelsmell
