If the aviation community wants to be respected and considered true aviators , then the level of public interest, low or not, shouldn't be used as an excuse for not investigating accidents and incidents correctly and thoroughly. Most cases seem to indicate an attitude of "Don't go looking too hard and chasing the real facts, in case you might find something you don't want to be found". Also, it doesn't cost a great deal to carry an effective investigation, so the availability of formal funding shouldn't really play a part either. If you can carry out basic troubleshooting, etc., you have the foundation skill set to carry out/play a part in an investigation. Long story short, it can be down to having the right Attitude and Approach. Cheers
