Of Metal Specifications, Thread Pitch And Torque

A number of years ago, a fellow owner and I both noticed an unusual shimmy in the main gear of our 182 on landing roll out. My first thought was a warped brake rotor, but the vibration didnt seem to be affected by the application of brakes. Hmm. While it didnt seem like a big deal, it wasnt right either, so we had the mechanic take a look.

Key Takeaways:

  • Unusual aircraft vibrations can indicate critical underlying issues, such as a metal fatigue crack in a landing gear bolt that was on the verge of complete failure.
  • Incorrect installation or missing components during maintenance, even for seemingly simple tasks, can lead to immediate part failure due to excessive stress, as demonstrated by the broken tailwheel wishbone.
