Tamarack Aerospace Group Initial Response to NTSB Report Docket (May 6, 2021)

Regarding Fatal Cessna Jet Accident– Location: Near Memphis, Indiana, November 30, 2018

Tamarack extends its deepest condolences to the families of Wayne Estopinal, Andrew Davis, and Sandy Johnson, who were killed in the November 30, 2018 aircraft accident in Memphis, Indiana. Deepest sympathies are also extended to the friends and colleagues affected by the tragic accident.

On May 6, 2021, the NTSB released factual information about the accident that analyzes the wreckage, and also includes among other things, specific consideration of components of the Tamarack Active Winglet installation. The NTSB’s released information also analyzes other factual data compiled during the investigation including available flight data, and an Aircraft Performance Survey compiled by NTSB.

Tamarack had access to some of the body of factual data when submitting the Party Submission which is included in the docket.  Party submissions are a standard part of all investigations, providing the party members’ analysis of the factual data to supplement the NTSB’s final report. The Tamarack submission can be downloaded here.

Tamarack has fully cooperated with the NTSB during this investigation, after being invited to participate in May 2019. Today the public has access to the factual reports and other information used by the NTSB and the various party members that will be used to determine the probable cause of the accident. Per typical investigation procedure, this docket of information is being made available before the NTSB issues the Final Report. Tamarack continues to support the efforts of the NTSB and awaits the release of the NTSB Final Report.
