FAA SAFO Advises Checks on PT6A Engines
The FAA issued the SAFO out of concerns about improperly installed beta arms during maintenance on PT6A engines.

A recent FAA Safety Alert for Operators (SAFO) is warning about a potential installation issue with reversing levers (beta arms) and related components on Pratt & Whitney Canada PT6A engines. The SAFO advises maintenance personnel and facilities to verify that the beta arm and guide pin are correctly installed, and, if not, fixed.
