What a perfect fit for Murphy's law.
A catalog of errors would need to have taken place for the wrong size pin to be fitted as at some point someone would be faced with fitting a large pin in a small hole, penny should drop at this point.
If a pin was replaced and the wrong pin identified in the IPC it could be possible.
Someone would have commented that the FWD servo input required a lot of adjustment post MRH change.
Some very clunky take off and landings plus a 5R vibration should raise eyebrows.
