What the agency says
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by reports that the identification plate affixed to certain tail cone assemblies contains an incorrect part number (P/N), which may not accurately convey the life limit. This AD requires verifying the tail cone assembly part number and, if necessary, replacing the incorrect tail cone assembly identification plate with a new tail cone assembly identification plate containing the correct P/N and updating the existing log book or equivalent record for the helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
