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.


DATES:
 
This AD is effective December 12, 2018.


We must receive any comments on this AD by January 11, 2019.

SUPPLEMENTARY INFORMATION:


Discussion


We issued AD 2018-20-03, Amendment 39-19437 (83 FR 50821, October 10, 2018), (“AD


2018-20-03”), for 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. 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.


Actions Since AD 2018-20-03 Was Issued


Since we issued AD 2018-20-03, we determined that we inadvertently included all Hoffmann


S/N model HO-V 62 propeller blades without a change letter “A” or “B” suffix in the applicability


and installation prohibition paragraphs of this AD. This AD corrects the applicability and installation


prohibition paragraphs to affect only Hoffmann model HO-V 62 propeller blades with S/N 1 to 6049,


inclusive. We are issuing this AD to address the unsafe condition on these products.


Related Service Information


We reviewed Hoffmann Propeller GmbH & Co. KG Service Bulletin (SB) E34 Rev. B, dated


September 18, 2017. The SB describes the instructions for the removal and installation of the


propeller blades. This service information is reasonably available because the interested parties have


access to it through their normal course of business or by the means identified in the ADDRESSES


section.
