The fuel system, electric equipment of fuel tank and wiring, fuel flammability, mechanisms of electrical ignition and possibility of explosion of fuel-air mixture as a result of arcing and/or static electricity in fuel tanks of commercial aircraft has been analyzed. Approximate equations for minimum ignition energy (MIE) in fuel tanks have been derived. Examples of explosions of fuel tanks include the air crash of Boeing 747-131 TWA 800 on June 17, 1996 and explosion of Boeing 727-200 at Bangalore Airport on May 4, 2006. Although probability of explosion of fuel in the wing tanks due the electric short circuit, arcing or static electricity is low, this problem should be always carefully considered in examinations of air crashes.

Przedstawiono analizę ukladu paliwowego, wyposażenia elektrycznego i przewodów zbiorników paliwa, zapalności paliwa, mechanizmów zapłonu elektrycznego oraz możliwosci wybuchu mieszanki paliwo-powietrze na skutek luku elektrycznego lub ładunków statycznych w samolotach pasażerskich. Zostaly wyprowadzone zależności do obliczeń przybliżonych minimalnej energii zapłonu w zbiornikach paliwa. Do wybuchów zbiorników paliwa doszlo podczas lotu Boeinga 747-131 TWA 800 17 czerwca, 1996 oraz podczas postoju Boeinga 727-200 na lotnisku w Bangalore 4 maja 2006. Chociaż prawdopodobienstwo wybuchu oparów paliwa w zbiornikach paliwa na skutek zwarcia instalacji, luku elektrycznego czy też ładunków statycznych jest niskie, problem ten powinien być zawsze dokładnie rozważony podczas badań wypadków lotniczych.
