Charleston Air Force Base was on emergency alert Tuesday afternoon when a C-17 crew reported the landing gear was stuck, but the problem was fixed without incident, according to officials.

The Ashley River Fire Department sent two units to the base about 4 p.m. and stayed about 45 minutes until the control tower confirmed that the landing gear was down, Chief Scott Inabinet said.

According to base officials, a C-17 was returning from a local training mission about 3:48 p.m., when the nose gear initially failed to lower. An emergency was declared as a precautionary measure. The landing was delayed while the crew went down the checklist to safely lower the landing gear. The plane landed without incident about 4:41 p.m.

"Our C-17 air crews are highly trained for all emergency situations," Col. John Wood, 437th Airlift Wing commander, said in a statement.
