## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain serial numbered (SN) propeller blades installed in Hamilton Sundstrand Corporation (formerly Hamilton Standard Division) 568F propellers. This proposed AD would require replacement of propeller blades, part numbers (P/N's) R815505-3 and R815505-4 that have a serial number (SN) of FR1699 to FR20021010, with serviceable blades. This proposed AD is prompted by reports of these composite propeller blades found at inspection, with random areas of missing adhesive under the compression wrap, which exposed the steel tulip part of the blade. We are proposing this AD to prevent propeller blade failure due to corrosion-induced fatigue, which could result in blade separation and possible loss of airplane control.
