Here are the actual bulletins hot off the press in brief---see the full attachments for the full ASB:
Bell has determined that some main rotor hub strap pins P/N 204-012-104-005 may have not been manufactured in accordance with the engineering design requirements and may shear as a result of the non-conformance.
Although the investigation remains in progress, this ASB mandates that the suspected strap pins with serial number prefix “FNFS” be immediately removed from service. Applicability of this bulletin to any spare part shall be determined prior to its installation on an affected helicopter.
