The airworthiness directive
47-51-05 CURTISS-WRIGHT Applies to Model C-46 Series Aircraft Equipped with Aileron Horn Assembly, Curtiss-Wright P/N 20-050-5715.
Compliance required within 100 hours' time in service after the effective date of this amendment unless already accomplished.
The aileron horns part 20-050-5715 have failed due to cracking of the horn between the attaching bolt holes and the outer edge. Inspection should be made to determine if this part has been replaced by P/N SK-10213. If not, part 20-050-5715 which is a casting should be replaced by a machined horn manufactured from 24ST material in accordance with Curtiss-Wright Drawing No. SK-10213.
(Army Technical Order 01-25L-102 also covers this same subject.)
