Airworthiness Directive · Amendment 39-19437 · Propeller assembly
Hoffmann GmbH & Co. KG Propellers
Superseded. A later AD replaced this one: AD 2018-20-03 R1. Comply with the one in force.
This AD applies to Hoffmann GmbH & Co. KG model HO-V 62 propellers without modified blades marked with change letter “A” or “B” suffix to the serial number (S/N).
We are adopting a new airworthiness directive (AD) for certain Hoffmann GmbH & Co. KG model HO-V 62 propellers. This AD was prompted by the failure of the propeller blade lag screws. This AD requires removal of the affected propeller blades and installation of modified propeller blades marked with change letter "A" or "B." We are issuing this AD to address the unsafe condition on these products.
Within 30 days of the effective date of this AD, remove the applicable propeller blades and install modified propeller blades marked with a change letter “A” or “B” suffix to the S/N marked on the blade.
After the effective date of this AD, do not install a propeller blade if it is not marked with a change letter “A” or “B” suffix to the S/N marked on the blade.
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.
