KERRVILLE, Texas – UPDATE: The National Transportation Safety Board expects its investigation into the plane crash to take months.
"The purpose of the NTSB investigation is pretty simple. We'd like to prevent future tragedy, and to do that, we look at all the factors that might of been at play with the accident," said Mike Folkerts, air safety investigator for NTSB.
Folkerts said the twin-engine Beechcraft BE58 left Houston at about 7:30 a.m. with a total of six people on board.
"The last air traffic control data was captured at 8:50 (a.m.) central time. The aircraft was at 2,000 feet above sea level, which is about 200 feet above the ground level," Folkerts said.
The plane crashed shortly after. Every single person on board was from Houston, including the pilot, 65-year old Jeffrey Weiss.
"(He was a) Very experienced pilot, over 5,000 flight hours," Folkerts said.
Folkerts said the NTSB will release a preliminary report next week. The full report is expected in 12 to 18 months.
Jeffrey C. Weiss, 65, was piloting the twin-engine Beechcraft BE58 that crashed Monday in Kerrville, killing six people, including himself.
Weiss had several planes in addition to the BE58, three of which are kept at West Houston Airport, which he has been flying out of for 15 years, according to KPRC.
He was the senior vice president of investments at Raymond James and Associates in Houston, according to the Associated Press.
The five other victims of the flight were:
Stuart Roben Kensinger, 55, of Houston
Angela Webb Kensinger, 54, of Houston
Mark Damien Scioneaux, 58, of Houston
Scott Reagan Miller, 55, of Houston
Marc Tellepsen, 45, of Houston
Angela Kensinger worked at St. John's High School as a lacrosse coach, and her husband, Stuart, worked in the real estate business as an investor.
According to the Associated Press, Marc Tellepsen was a landscape architect, and he and his associate, Mark Scioneaux, were on a scouting trip along with architect Scott Miller.
West Houston Airport manager Woody Lesikar told KPRC that Weiss was known for his giving nature and charitable acts, like flying to pick up kids and people with medical issues and helping veterans.
Lesikar also noted that Weiss took part in a program that picked up stranded pilots.
Weiss averaged 40 hours of flight time per month, equivalent to an average of 500 hours a year, according to KPRC.
