Narrative:

There was a leak in engine #1. They boarded the plane then took the people off. The whole flight crew was on the plane -- and the caterers; when the mechanics started up the engine endangering our safety and violating an far. Supplemental information from acn 803857: there was a leak of gasoline from engine #1. Mechanics had to perform the engine check (run the engine) so everybody was supposed to leave the airplane. Without checking if airplane was empty; they started the engine. There were still flight attendants on board and also 2 passenger waiting for a wheelchair. Caterers were also on board. We left airplane with these 2 passenger as soon as we could (about 1 min) but caterers were boarding the galley for the whole time of the engine performance check.
