TukTuk BoomBoom, thanks for the clarification. It is the seemingly inconsequential things that lead to catastrophic failures.
Like the Colgate BK117 fin failure, which brought to light the improper and potentially disastrous substitution of solid rivets with blind rivets by some AME's during repairs and modifications, and the FU-24 fin failure in New Zealand due to the abrasion boot being trimmed with a knife after installation, which scored the skin, eventually leading to the departure of the complete fin assy in flight.
Sorry for the thread drift.
