The San Diego Sheriff's Department (SDSO) helicopter, ASTREA, was forced to make a precautionary landing at Poway High School.
The helicopter had mechanical issues while in the air and landed at the school, located at 15500 Espola Road, at approximately 2:38 p.m., deputies said.
The copter was flying southbound over Poway when the crew heard an unsafe noise, deputies said.
The pilot did not see any instrumentation lights or warnings, so as a precaution, he landed on the ball field at the school.
"There was no danger to the public at any point," Lt. Emory Wallace said in a statement. "No students were in the area where the aircraft landed."
The Poway Unified School District said there were many first responders on scene when the helicopter landed to secure the perimeter and bring in a mechanic as soon as possible.
Once mechanics make needed repairs, the copter will be flown to Gillespie Field.
No one was injured.
Officials are making repairs on site at the school.
No other information was immediately available.
