Airworthiness Directive 2018-20-03
one-timeAirworthiness Directives; Hoffmann GmbH & Co. KG Propellers
What this AD requires
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.
Which aircraft AD 2018-20-03 applies to
Applies to propellers with a propeller blade S/N 1 to 6049, inclusive. Blades marked with change letter 'A' or 'B' suffix to the S/N are not affected.
Whether AD 2018-20-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
