LOUISVILLE, Ky. — A company that designed part of a jet that crashed in Southern Indiana last year has filed for bankruptcy.

It comes almost seven months after that crash that killed Louisville City FC cofounder Wayne Estopinal and two others.

In a statement, Tamarack Aerospace says its decision to voluntarily file for bankruptcy is directly related to the FAA's decision to ground all Citation Jets with an ATLAS winglet made by the company. They are meant to reduce drag and help the pilot better control the plane.

Estopinal's plane was one of the first to have those winglets installed.
