During approach to Berlin-Schönefeld runway 25L, the crew kept autopilot activated beyond specified altitude, leading to an excessive descent rate. The aircraft impacted the runway, left wing detached, and it came to rest inverted. All 74 occupants evacuated; eight seriously injured.

Incident Overview

An aircraft on approach to Berlin-Schönefeld Airport runway 25L completed the final approach with the autopilot engaged. According to standard procedures, the crew was expected to disengage the autopilot at an altitude of 120 meters. However, the captain decided to continue the approach with the autopilot active and used elevator inputs to counter the autopilot's commands.

Sequence of Events

During the last segment of the approach, the rate of descent increased to between 6 and 8 meters per second. The airplane subsequently struck the runway surface. Upon impact, the left wing was torn off. The aircraft, now out of control, veered off the runway and came to rest upside down in a grassy area approximately 400 meters from the initial point of impact.
