Counterfeit Bolts and Tiny Maintenance Mistakes

Examines two fatal aviation accidents, each initially mysterious but later traced to critical maintenance and component failures. The first case involves the 1989 crash of Partnair Flight 394 into the North Sea. Investigators determined that the tail section failed due to unapproved, counterfeit bolts, with a malfunctioning auxiliary power unit worsening the structural weakness, causing the aircraft to disintegrate mid-flight. The second account covers the 1975 crash of an overloaded C-5A Galaxy during Operation Babylift. Improperly installed and rigged tie rods on the cargo door locking mechanism failed in flight, causing the door to detach, resulting in explosive decompression and loss of control. Both incidents underscore the critical importance of proper maintenance, verified components, and rigorous operational procedures, as well as the complexity of aviation accident investigations that ultimately drive safety improvements in both commercial and military aviation.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/Air_Crash_ChroniclesProduced by Podcai Studio:https://www.podcaistudio.com/
