(WEAU) -- A new report from the National Transportation Safety Board says the pilot of a plane that crashed and killed an Eau Claire woman didn't have a valid medical certificate at the time of the flight.
Eunyoung Kim Reneau was killed in the crash in Missouri in March of 2011.
Investigators say the weather at the time was marginal with low clouds.
The NTSB says the pilot never got a weather briefing before the flight, and didn't have an instrument rating allowing him to fly in bad weather.
The plane was headed from Florida to Eau Claire when it went down, killing all three on board.
A local family has confirmed it was an Eau Claire woman who died in a Missouri plane crash.
The family of Eunyoung Kim Reneau says she was one of three on board when the single-engine Piper Lance went missing Last Sunday.
The plane was on its way from Arkansas to Wisconsin.
Civil Air Patrol found that crash site in southeast Missouri late Friday night, just eight miles southeast of Ironton.
It reports there were no survivors in the crash.

CHESTERFIELD, MISSOURI – Missouri Wing Civil Air Patrol aircrews have located the plane that went missing on Sunday in southeastern Missouri. The persons onboard the Piper Lance did not survive.
Civil Air Patrol spokesperson Lt. Colonel David Miller said the plane was located in an area approximately 8 miles southeast of Ironton in Madison County, Missouri. The area of interest was identified late in the early evening by an aircrew and was verified as the crash site by local law enforcement at approximately 11:45 PM Friday night.
The Civil Air Patrol began their search Monday morning for the Piper Lance, which was lost from radar contact early Sunday morning near Doniphan, Missouri. The airplane was traveling from Arkansas to Wisconsin.
Aircrews discovered the debris field while they were conducting today’s search and were able to direct local law enforcement to the location who verified the wreckage and that there were no survivors..
At this time the name of passengers involved have not been released. Additionally, the cause of the crash has yet to be determined.
The Civil Air Patrol utilized over 50 personnel and seven CAP aircraft in the extensive five day search, including multiple aircrew and ground teams from across the state. The search covered more than 5,100 square miles and was made difficult by inclement weather, rough terrain, and no emergency locator transmitter signal heard.

Crews are still searching for an Eau Claire woman who was on a small plane that went missing on Sunday.
The Missouri Wing of the Civil Air Patrol, U.S. Air Force Auxiliary, says three aircraft and one ground team are searching northern areas near Farmington, Missouri. Family members are also continuing to assist the search efforts.
Family members say Kim Reneau was on her way home from a business trip in Florida with two friends. The small personal aircraft went missing in-route to Eau Claire. The plane was scheduled to arrive in Eau Claire early Sunday morning. Reneau owned a restaurant in the area for several years.
