KG Propellers AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. –––––––––––––––––––––––––––––––––– SUMMARY: We are revising airworthiness directive (AD) 2018-20-03 for certain Hoffmann GmbH & Co. KG (Hoffmann) model HO-V 62 propellers. AD 2018-20-03 required removal of the affected propeller blades and installation of modified propeller blades marked with a change letter “A” or “B” suffix. This AD requires the removal and replacement of the affected propeller blades and installation of modified propeller blades marked with a change letter “A” or “B” suffix. This AD was prompted by a determination that the applicability and installation prohibition paragraphs of AD 2018-20-03 were incorrect. We inadvertently included all Hoffmann model HO-V 62 propeller blades that did not have a change letter “A” or “B” suffix added to the serial number (S/N) and marked on the blade in the applicability and installation prohibition paragraphs of AD 2018-20-03. Only Hoffmann model HO-V 62 propellers with certain S/Ns without a change letter “A” or “B” suffix are affected. We are issuing this AD to address the unsafe condition on these products.

AD 2018-20-03 resulted from the failure of the propeller blade lag screws. We issued AD 2018-20-03 to prevent failure of the propeller.
