In January 2026, investigations into a Taiwanese F-16V crash identified critical failures in the Modular Mission Computer (MMC), which serves as the central processing unit for the aircraft’s avionics and flight systems.
The primary known issues include:
- Loss of Flight Data: Major malfunctions can cause the aircraft's flight path and attitude data to stop displaying. In the January 2026 incident, this left the pilot without a horizon reference while flying in clouds at night, leading to severe spatial disorientation.
- Software Instability & Memory Limits: Reports from military whistleblowers allege that the F-16V upgrade introduced unstable software and insufficient memory, resulting in unpredictable computer failures. This performance has been described as less stable than the original Block 20 aircraft.
- "Ghost Turns": Malfunctions have been linked to uncommanded, violent "ghost turns" (rapid rolling maneuvers) that exceed normal flight limits without pilot input. This issue reportedly worsened after a flight control system update to version 4.3 in 2024–2025.
- System Failure Severity: The Air Force identifies "several levels" of MMC malfunctions. While some are considered "common malfunctions," others are severe enough to disable primary navigation and safety systems.
- Lack of Automatic Recovery: The current fleet allegedly lacks a fully operational Automatic Ground Collision Avoidance System (AGCAS), which could have otherwise corrected the aircraft's flight path during a mission computer failure.
The Taiwanese Air Force is currently working with U.S. manufacturers to develop software patches and expedite updates to improve MMC reliability across the fleet.
