Textron Lycoming did not specifically respond to recommendation R20010256, but on 12 February 2002, in comment with respect to the content of the ATSB's final report stated; "Lycoming does not concur with the specific findings in ATSB report 200002157 that attribute the failure of the left engine to the presence of anti-seize compound between the bearing and the connecting rod journal."
