Letter Contends That Inconsistencies and Discrepancies Call NTSB Assertions Into Question
Tamarack Aero has formally requested the National Transportation Safety Board reassess its report of a 2018 CitationJet Mishap that occurred near Memphis, Indiana.
The company insists that the NTSB's relative unfamiliarity with their equipment led to a premature assignment of blame, and that the board failed to evaluate the factual information of the case.
The NTSB's final report on the crash that killed the pilot and 2 passengers levies blame on the CJ2+ equipped with Tamarack's Active Winglets. Tamarack maintains that the incident is not the result of their equipment, proven with an assortment of evidence. The final report contains facts pertaining to the systems, the aircraft's performance, the CVR, and computed tomography that Tamarack asserts clear its Active Wing systems. "Overall, the errors and gaps in the factual record are so fundamental that the NTSB must reconsider and modify its determination of probable cause of the accident. As but one example of the NTSB’s failure to properly consider key information provided by Tamarack," said the company in its letter.
The letter also brings attention to the lengthy delay in publication, especially the relation between the investigative process and the relative immediacy of publication without sufficient time to assess their submitted evidence. Tamarack is the inventor, the expert of their systems, but they seem to have been somewhat disconnected from the investigation. "The NTSB published its Final Accident Report for this accident on November 1, 2021 – 4 business days after Tamarack submitted its supplemental party submission. There is nothing in the public docket or the Final Accident Report that addresses any information contained in the Tamarack supplemental submission. Given that the accident occurred 35 months prior to the date of publication of the Final Accident Report, it is difficult to comprehend why the NTSB published its Final Report a mere 4 business days after receiving the new information contained in Tamarack’s supplemental party submission without even
acknowledging the existence of that supplemental submission."
The facts enclosed bring attention to the incompatibility of certain indications, autopilot settings, inconsistencies, and discrepancies of the data. Only time will tell whether their supplemental information will net the company a reconsideration, or if the accident receives a higher level of scrutiny. Tamarack feels that the report unfairly maligns their name, and they insist that the victims of the crash, and those who could eventually suffer from a similar flight condition, deserve an earnest, accurate assessment.
