A California woman and her two sons have died in a horrific plane crash that severely injured her husband, The Post has learned.

Danna Eady, 41, a flight instructor from Auberry, was killed along with her boys Pavel and Remus when their aircraft went down on a hilltop near Sierra Sky Park airport in Fresno on Saturday.

Her husband Craig, who was also on the plane, survived but suffered severe burns and extensive injuries, friends said. Danna is also survived by her other children Lucien, 17 and Felicity, 18.

A SupportNow page says: “[Craig] now faces a long and difficult road of surgeries, rehabilitation, medical care, and recovery. His care is expected to continue for at least the next six months and likely well beyond that.”

The page, started by family friend Julie Lovell, says all the funds raised will go to ongoing medical care for Craig, the family’s household needs and any unexpected costs that come after the tragedy.

Nick Wilcox, who owns the Soar Paso flight school in Paso Robles, described Eady as a dear friend and fellow flight instructor who had flown with him numerous times and had even taken his daughter flying.

He told The Post: “She was a very special soul.”

Wilcox said Danna was deeply involved in the Fresno-area aviation community, where she worked as a flight instructor at Reedley College and served as president of the local Experimental Aircraft Association chapter.

Her impact was evident after the crash, he said, by numerous current and former students wishing her well. “She was a very large presence in the Fresno flying community,” Wilcox said.

But beyond aviation, Wilcox remembered Danna for her adventurous and outgoing personality. He described her as “bubbly, outgoing, a free spirit” who loved being barefoot, eating ice cream, traveling and having new experiences.

Flying was Danna’s passion, Wilcox said. Although she had only become a pilot in recent years, Wilcox said she quickly accumulated thousands of flight hours and earned numerous ratings.

“Her dream was to fly,” Wilcox said. “She died doing what she absolutely loved.”

The crash happened in northwest Fresno near the San Joaquin River just before 2 p.m. Saturday, sending emergency crews scrambling to the scene.

Tony Botti, a public information officer for the Fresno County Sheriff’s Office, told The California Post authorities got the call around 1:50 p.m. about a plane crash near the far north end of Blythe Avenue, close to Sierra Sky Park.

Firefighters, cops and sheriff’s deputies arrived to find plane wreckage on a bluff near the river as flames tore across a nearby hillside.

Eady and her husband were rushed to a hospital in critical condition at the time. The two sons, however, were declared deceased at the scene.

What caused the plane to go down remains unclear as investigators begin piecing together the crash.

The Federal Aviation Administration and National Transportation Safety Board are both involved, Botti said, with the NTSB taking the lead in determining what went wrong.

A secured perimeter was thrown around the wreckage Saturday to keep people out and give crews room to work.

“Firefighters were able to extinguish the flames and prevent them from spreading onto the properties of nearby homes,” the Fresno Count Sheriff’s Office said in a statement.
