ALPENA — MyMichigan Health President and CEO Diane Postler-Slattery and her husband died after a plane crash in Florida on Tuesday evening, the health system reported.

The single-engine Cessna 182 crashed Tuesday night in a wooded area some two miles from Northwest Florida Beaches International Airport in Panama City, Florida, the Federal Aviation Administration said.

The Bay County Sheriff’s Office identified the occupants as MyMichigan Health President and CEO Diane Postler-Slattery and her husband, Donald Slattery. Sheriff’s officials said the plane was approaching the airport around 7 p.m. when it disappeared from the radar. Multiple agencies were involved in the search for the aircraft, which was eventually found using drones in a densely wooded area.

A National Transportation Safety Board investigator was traveling to the scene to examine the aircraft, the agency said Wednesday.

As part of the investigation, NTSB will request radar data, weather information, air traffic control communication, maintenance records and the pilot’s medical records, the agency said.

Postler-Slattery was a key contributor in the transition of ownership of the former Alpena Regional Medical Center from Alpena County to then-MidMichigan Health in 2016.

A preliminary report, which includes the factual information gathered, should be published in about 15 days.

Investigations involving fatalities typically take between 12 and 24 months, the agency said.

Postler-Slattery served as head of the health system since 2013.
