In the review report(published 1999)of the original accident investigation report into the accident of EI-AOM on 24/03/68, it mentions that a 1/2" crack was found in the fuselage skin and was recorded in the aircraft log book on 05/02/68 as a possible reason why the aircraft did not fly on that date. I have been unable to find any other reference to this in the rpeort and I am very mystified as no satisfactory reason has ever been given for the cause of this crash! I wonder if such a small structural fault could eventually lead to a catastrophic failure which could possibly explain what caused this mishap?

Any aircraft experts out there?
