UPDATE, June 17 | The Kansas Highway Patrol has released its report into Monday's crash.
The two people on board have been identified as a 73-year-old Lee's Summit man and a 30-year-old Arkansas woman.
The report indicates the aircraft was flying south when the left engine experienced a mechanical malfunction and became inoperable. The pilot, identified as the 73-year-old, lost control of the airplane and crash-landed on top of the hangar.
Investigators from the National Transportation Safety Board and the Federal Aviation Administration were anticipated to arrive at the crash site late Monday or early Tuesday morning.
ORIGINAL REPORT | Two people on board a twin-engine plane were injured Monday afternoon after their plane crashed on top of a hangar at New Century AirCenter.
Around 1:15 p.m., crews received reports that an aircraft was on top of a hangar at the airfield.
A county spokesperson said the plane, a twin-engine Beechcraft King Air 90, landed on top of the Butler Avionics Hangar.
According to the Kansas Highway Patrol, the plane had been cleared for landing just before the incident.
The two occupants of the plane, a pilot and a trainee, were rescued from the roof and transported to an area hospital with non-life-threatening injuries.
A KHP spokesperson did not know which person was flying the plane at the time of the accident.
"The good news is that the two people that were occupying the aircraft sustained minor injuries and exited the aircraft under their own power," Johnson County Airport Commission Executive Director Bryan Johnson told reporters Monday afternoon.

Online flight records from FlightAware show the aircraft took off around 1 p.m. Monday from Butler, Missouri. The first emergency crews were dispatched to New Century AirCenter about 15 minutes later.
In a statement to KSHB 41 News, a Federal Aviation Administration spokesperson said the FAA and National Transportation Safety Board will investigate the incident.
The spokesperson confirmed the flight originated from Butler Memorial Airport in Butler, Missouri.
Johnson said the aircraft might remain atop the hangar through Tuesday to give investigators a chance to detail the scene.

While the airport was closed briefly, it reopened for traffic around 2:20 p.m.
