The failure is currently believed to relate solely to Mills OEM equipment.

Why it happened
It is not currently known what the cause of the cracking is. Investigations are continuing.
Actions – Do not load the lifeboat with pennants in place until these actions have been completed
Installations or vessels with Watercraft lifeboats should confirm whether Mills release gear is fitted to the lifeboats; arrange for NDT inspection of the bottom forks of the pennants; arrange for pennants with cracks to be removed from service and replacement pennants sourced via the Lifeboats maintenance provider.
