On my recent trip between GRU and COR I was sitting on a A seat with direct view of the wing. I saw as we taxed out of GRU that some screws were missing on a metalplate covering the engine, just in front of the wing , 737-300. During flight I noticed that one more was missing. On the row there were around 8 screws of wich 4 now were missing, on the same frontrow. Suddenly my girlfriend saw that one more was coming up, just few minutes before landing. I took a photo of it. After landing at Ascuncion the screw now was gone. When passengers had disembarked I asked to talk with the captain. I showed him the photos and of course he was very calm. Unsuccesfull on entering the wing the captain came back and I showed him the area. Nothing really happened after that so i asked what he should do about it. Nothing appearantly. So I said if they shouldnt make sure that not more screws were falling of during our last leg. So after some minutes a man came out on the wing and started titghtening the screws we had left. in my opinion the screws were not mandatory for the flight but since we are talking about screws very close to the engines opening I was a bit concerned. Also because we had hit som turbulence and it was supposed to get worse. Next this is that all screws were falling out of the front row of the plate (apx 40*20cm) and with the air coming towards at 800kph it could cause us some trouble.

My question, should I do something with my photos? Perhaps blackbailing the ompany :-)
