A small plane crashed into a building Tuesday morning at the Ak-Chin Regional Airport in Maricopa, officials said.

A single-engine Ercoupe 415-C crashed under unknown circumstances into an airport building shortly after taking off around 8:30 a.m., according to Ian Gregor, a spokesman for the Federal Aviation Administration.

Two people were on board the airplane, and both were taken to a hospital, Gregor said.

The pilot’s condition wasn’t immediately clear. No one inside the building was hurt, community operations manager Bart Smith said.

Local police and fire units were at the scene investigating as of 10 a.m., Smith said.

It wasn’t immediately clear what caused the crash. The FAA and NTSB will investigate, according to Gregor. 

The NTSB is the lead investigative agency. It typically takes the NTSB a year or more to determine a probable cause for an accident.

No further details were available.
