(Helicopter crash update)

Investigators have confirmed that a second person died aboard a helicopter that crashed Tuesday morning in an alfalfa field at the Fort McDowell Yavapai Community near Fountain Hills.

Officials have not confirmed the identity of either person on board the chopper; however, both have been identified by their employers as they were apparently involved in a test flight at the time of the crash.

The pilot was identified as an experienced pilot and instructor for the Embry-Riddle University Prescott campus, Runcie Moore. The passenger was identified by Van Horn Aviation of Tempe as Stephen Estes, an engineer with that firm.

The chopper went down at about 7 a.m. in a field near the Verde River. The crash resulted in a fire and both men died at the scene.

Dr. Frank Ayers, Chancellor at the Embry-Riddle Prescott campus, issued a statement to the media calling Moore an “outstanding pilot, Army veteran and decorated helicopter test pilot with the Army.”

“His many contributions to education of our students, including his extensive experience, was immeasurable,” Ayers said.

Estes earned a Masters degree in aerospace engineering from Arizona State University and was employed by VHA as engineering manager for the company.

A statement on the VHA website said Estes was instrumental in the design and analysis of current rotor blades.

“We mourn the loss of our friends during this tragic accident,” VHA President Dean Rosenlof said in the statement. “Both men contributed greatly to the design and development of our most recent rotor blade designs. Their passing will leave large holes in our company and they will both be missed personally and professionally.”

According to the statement, VHA representatives have reached out in support of the crewmembers’ families and are working with local, state and federal authorities in their investigation of the accident.

The helicopter reportedly lifted off from Falcon Field in Mesa prior to the crash. One witness reported hearing a bang before seeing the helicopter drop from the sky, according to fire officials.

The cause of the crash is unknown. The National Transportation Safety Board (NTSB) has taken over the investigation.
