Piedmont Airlines Flight 22 investigation
As NTSB Chairman, Rosenker ordered the 2006/2007 re-opening of the controversial 1967 investigation of Piedmont Airlines Flight 22. In the official petition for reconsideration, Paul Houle (an amateur historian who asked for the investigation to be reopened) suggested that numerous important facts were missing from the original investigation, as well as apparent potential conflicts of interest which should have been found at the time. Despite the cockpit voice recorder conflicting with the original NTSB report, the NTSB's Office of Aviation Safety found no compelling reason to make any changes to the report. Rosenker subsequently wrote to Houle, sharing the Board's findings upholding the probable cause and contributing factors as presented in the original NTSB report.
Rosenker was Managing Director of the Washington, D.C. office for the United Network for Organ Sharing (UNOS) from Oct 1999 to January 2001 when he joined the White House Staff. Prior to working for UNOS, Rosenker was the Vice President, Public Affairs for the Electronic Industries Alliance for 23 years.
