Aloha Airlines Flight 243

This incident changed the way they “aged” aircraft. Prior to this incident, they only looked at flight hours to determine how much life was left in the fuselage. The issue here is that this aircraft was only used to island hop between the Hawaiian islands. So the flight hours were really low, but the fuselage had tons of compression/decompression cycles on it bc of its history of very short flights. Way more compression/decompression cycles than the flight hours would normally indicate.
