There were 2 vendors supplying planetary gears...one was bad so they aren't used any more.
The transmission that failed had been dropped a few feet. That caused stress risers in some of the planetary gears which failed. Transmissions are now shipped in special containers with g meters on the outside & inside. If they are tripped, the transmission is returned for inspection.
There is a cycle penalty for external loads depending on which hook is installed.
I believe all this only applies to 225's and not 332's. |
