A woman was killed this morning south of Maricopa while tandem skydiving.

According to the Pinal County Sheriff’s Office, an instructor with Skydive Phoenix jumped with a 26-year-old woman over Hidden Valley. Their parachute failed to completely deploy, and the pair had a hard impact in a field northwest of Bowlin Road and Hidden Valley Road.

The woman was declared dead at the scene. The 40-year-old instructor had two broken legs and was transported to an emergency room. He is expected to survive.

The incident happened at 10:30 a.m. Names have not been released.

“PCSO will conduct the death investigation in conjunction with the Pinal Medical Examiner,” PCSO spokesman Mark Clark stated. “The FAA will conduct their own investigation to assure federal regulations were followed.”
