As a pilot your are always trying to improve your skills. Therefore it is always good to get reports on flight accidents, causes and possible failures. I actually like the Aviation Herald  quite much since it provides always the latest issues/incidents with quite good reports. Another quite good page is the Aviation Safety Network , which can provide you an overview of incidents for each year – which can be drilled down on the individual countries. If you are not a pilot please take in mind that flying is still the most safest way to travel. Businessinsider  gives you 12 reason for it.
Happy landings to all of you!
