The FAA is correcting airworthiness directive (AD) 2010-11-09, which published in the Federal Register. That AD applies to TAE models TAE 125-01 and TAE 125-02-99 reciprocating engines, installed in, but not limited to, Diamond Aircraft Industries model DA 42 airplanes. The part number for engine model TAE 125-01 is missing a digit in paragraph (c) and in paragraph (e)(3). This document corrects those part numbers. In all other respects, the original document remains the same.
