Gents , all fuel pumps are electrically powered and mechanically geared ... during refuelling , there are fuel vapors everywhere ...
i think that all of you will imagine easily what can happen in the case of a pump failure or whatever ...
i am sure that all of you heard about TWA800 and the SFAR88 ...
in maintenance , we must study and practise the FTS and CDCCL , maybe you should read stuff about these ... again , just my 2 cents ...
