Bulgaria reported a malfunction in the first US-supplied F-16 fighter.

The Bulgarian Air Force has detected a malfunction in the first F-16 Block 70 fighter jet delivered from the United States. This was announced on April 30 on the website of the Ministry of Defense of the country.

It is noted that technical problems were discovered after the plane landed.

"A deviation in the operation of one of the systems was detected, which does not mean that the plane crashed," the ministry said in a statement.

According to the commander of the Bulgarian Air Force, Major General Nikolai Rusev, the F-16 Block 70 has not yet been definitively adopted, this will happen after the completion of the technical and flight acceptance procedure.
