KUNSAN AIR BASE

F-16CM Landing Gear Failure & Ejection; Kunsan Air Base, Korea (HUD)

8,305 views Oct 2, 2022 At 1537 hours local time on 2 December 2019, an F-16CM Block 40, tail number 90-0714, crashed in between Runway 36 and Taxiway P on Kunsan Air Base (AB), South Korea. The Mishap Pilot (MP) was an instructor-pilot assigned to the 80th Fighter Squadron. The MP was returning to Kunsan AB for landing after completing a local continuation training sortie. Upon initial contact with the runway, the mishap aircraft's (MA) right main landing gear (RMLG) collapsed. The MA departed the runway and the MP successfully ejected. There were no casualties and no loss of civilian property. The MA, valued at $19.4 million, was completely destroyed. The MA was assigned to the 8th Fighter Wing, Kunsan AB, South Korea.

When the MA initially touched down on the runway, the RMLG collapsed and the MA yawed to the right. The MP attempted to keep the MA on the runway and take the MA airborne again, but was unsuccessful. The MP safely ejected from the MA suffering only minor injuries. The MA remained upright and skipped across the infield intermittently becoming airborne and settling back onto the field. The MA eventually stopped approximately 2,200 feet from the initial touchdown point, and the MA rotated 150 degrees from the initial runway heading. The engine continued to run for more than one hour after the mishap.

The Accident Investigation Board President found, by a preponderance of evidence, this mishap was caused by a failure of the RMLG downlock actuator, causing the RMLG to collapse, making the aircraft uncontrollable during the landing phase of flight. Specifically, the tension on the main landing gear was great enough to overcome the force of the downlock actuator, resulting in a collapse of the RMLG. This is a known issue for F-16C/D blocks 40/42/50/52 and is addressed by Time Compliance Technical Order 1F-16-2855.
