## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 airplanes. This proposed AD was prompted by a determination that a certain bolt used on the outboard clevis of the ram air turbine (RAT) forward support fitting might not be long enough to allow for proper installation of the RAT. This proposed AD would require inspection of the forward support fitting of the RAT and replacement if cracking is found, and installation of a longer shoulder bolt. We are proposing this AD to address the unsafe condition on these products.
