Summary
We propose to adopt a new airworthiness directive (AD) for certain Hoffmann Propeller GmbH & Co. KG model HO-V 62 propellers. This proposed AD was prompted by the failure of the propeller blade lag screws. This proposed AD would require removal of the affected propeller blades and installation of modified propeller blades marked with change letter ``A'' or ``B.'' We are proposing this AD to address the unsafe condition on these products.
