Background: There have been reports of fuel leaks which have resulted in fire warnings and inflight shutdowns. The majority of these fuel leaks have occurred shortly after fuel manifold maintenance. The manufacturer has advised that the fuel manifold transfer tube lockplates are sensitive to installation errors and are a contributing factor to the fuel leaks.
