Updated at 4:45 p.m.: Revised to include the name of the last of the 10 victims to be publicly identified.

A cockpit recording from the plane that crashed Sunday at Addison Airport, killing all 10 people aboard, captures the moments when the crew recognized a problem with the left engine, officials said Tuesday.

The audio reveals a mood "consistent with confusion" just after the Beechcraft Super King Air 350 took off and about 12 seconds before the recording ends, said Bruce Landsberg, vice chairman of the National Transportation Safety Board.

The two crew members received three alerts warning they were in danger of hitting the ground three seconds before the recording broke off abruptly, presumably when the plane crashed into a hangar.

Eight passengers and two crew members were on the 2-year-old, twin-engine aircraft that was destroyed by flames after it crashed into the hangar at 9:11 a.m. Sunday as it departed for St. Petersburg, Fla. No one on the ground was hurt.

The cause of the crash remains unknown.

The victims included pilots Howard Cassady and Matthew Palmer; Brian and Ornella Ellard and their teenage children, Alice Maritato and Dylan Maritato; Steve and Gina Thelen; and John and Mary Titus.

All eight passengers were members of Bent Tree Country Club in Dallas, according to an email the club sent to members.

"The impact of their loss will be felt by many," club president Chris Hammons and general manager Dan Burkett wrote. "Please join us in offering heartfelt condolences, thoughts and prayers to their families and those closest to them, as well as to the families of the two pilots."

NTSB officials said a preliminary examination of the cockpit voice recording yielded two hours of high-quality audio, giving investigators a glimpse into the terrifying moments before the aircraft hit the hangar and burst into flames.

About eight seconds before the audio cut off, crew members said there was a problem with the left engine. Three seconds before the recording ended, a series of automated alerts warned the crew about the plane’s bank angle.

NTSB investigator-in-charge Jennifer Rodi said the fire destroyed most of the plane's fuselage, complicating the investigation and making surveillance video of the crash even more important.

Four cameras captured the takeoff and crash, officials said. Two of them sat at the end of the runway, giving slightly different angles on the aircraft’s liftoff and impact. They show that the plane began to veer left before it hit the hangar.

A camera near the start of the runway showed the plane lifted off and began to veer. A dashboard camera in a parked firetruck captured the crash itself.

Officials said microchips from cockpit control monitors were recovered and could allow investigators to understand how the crew was operating the craft before the crash.

Experts are pulling apart the plane’s engines and propellers to learn more about what caused the crash. They'll also review the flight records and experience of the crew and interview air traffic controllers who were on duty Sunday.

Officials said Tuesday’s briefing would be the last official update locally as NTSB employees prepared to return to Washington, D.C. Rodi and her team said they probably will be in Addison until Thursday.

The agency expects to have a preliminary cause for the crash in less than two weeks. A full report on the crash could take 18 months.

The NTSB did not release audio of the cockpit recording and said more information will be available later as the cockpit voice recorder is analyzed. The agency will release a written report after the investigation is complete, including a transcript of the cockpit recording. The plane did not carry a flight data recorder.

The victims

Howard Cassady, 71, was the last of the 10 victims to be publicly named. He and fellow pilot Matthew Palmer, 28, made up the plane's crew.

The Dallas County medical examiner confirmed Tuesday that it had positively identified everyone who died. Official rulings on their causes of death are pending while additional tests are conducted.

Also added to the medical examiner's list Tuesday were Mary Titus, 60, and her husband, John Titus, 59.

Both were members of Tennis Competitors of Dallas, according to an email from the group. Mary Titus served as the mixed league director, the group said.

Brian and Ornella Ellard were headed to St. Petersburg for summer vacation with Ornella's two children, 13-year-old Dylan Maritato and 15-year-old Alice Maritato, according to Patrik Bachmann, who said he was Alice's former boyfriend.

Alice would have been a sophomore at John Paul II High School in Plano in the fall. Dylan was entering eighth grade at All Saints Catholic School in Dallas. The children are survived by their father, Michele Maritato.

Brian Ellard, 52, owned an upscale Italian restaurant in Dallas, as well as an art gallery. Ornella Ellard, 45, worked as an interior designer.

Public records show that the Ellard family is connected to the business that bought the 2017 plane this year. EE Operations shares the same mailing address in Addison as Ellard Family Holdings LLC. Attempts to reach EE Operations have been unsuccessful.

Steve Thelen, 58, and his wife, Gina Thelen, 57, are survived by an adult son, Kyle, and daughter, Christy. A doting father and husband, Steve invited co-workers at the JLL real estate company to grill at the couple's Plano home, according to Victoria Reynoso, who said she had worked as his assistant.

Palmer, who lived in Fort Worth, was a lifelong member of DIDO United Methodist Church, where he and his wife of one year volunteered with the youth group, the Rev. Jana Wear said.

"He's the middle of the church; he's the backbone," Wear said. "It's a shocking loss."
