I know in Oz someone managed to get a lot of 58 bits into a 206.
The resulting vibration from incorrect NR and other issues and the intervention of
the authorities caused a lot of expensive parts to be thrown away!!
Bell are probably kicking themselves that they didn't make the parts just slightly different so they wouldn't physically fit.
A lit of PMA parts were manufactured with data from the DoD info in the "public domain" and reverse engineered.
