No hydrazine leak following F-16 emergency landing

A five-person hydrazine team from Gwangju Air Base confirmed there was no hydrazine leak from an F-16 Fighting Falcon following its emergency landing at Muan Airfield April 7.

The F-16 was conducting a routine training flight when it suffered a severe engine malfunction. The pilot executed emergency procedures and safely landed the aircraft.

"In emergency situations where the engine is about to fail, the pilot activates the emergency power unit (EPU) to ensure controlled flight to the nearest destination," said Lt. Col. Anthony Pelkington, 8th Operations Support Squadron commander. "The EPU uses hydrazine as its fuel source to get the aircraft safely to its destination. This fuel is not sprayed. It is utilized as any normal fuel source within the aircraft."

Hydrazine only leaks from the aircraft if the EPU malfunctions during the emergency procedure. If this occurs, there can be adverse health effects.

Since the hydrazine team determined there was no leak in this case, the population is safe from any hydrazine effects.

The cause of the engine malfunction is under investigation. Direct all questions to the 8th Fighter Wing Public Affairs office at DSN 315-782-4705/1497 or commercial number 063-470-4705/1497.
