The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand Propellers model 568F propellers with certain part number (P/N) and serial number (SN) blades. This AD requires removing affected propeller blades from service for rework. This AD results from reports of blades with corrosion pits in the tulip area of the blades. We are issuing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and loss of airplane control.
You are responsible for having the actions required by this AD performed within 30 days after the effective date of this AD.
Remove from service blades, P/Ns R815505R2, R815505R3, R815505R4, R815505S2, and R815505S3, that have a SN listed in Table 1 of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
