What happened
A positioning flight departed Hanover (EDDV) at 00:41 hours, destined for Munich (EDDM), with the intention of performing a subsequent air ambulance mission. During the initial climb, the crew received clearance to Flight Level 230. While en route, the crew was notified that the runways at Munich were temporarily closed for snow removal, prompting a reduction in airspeed.
During the descent phase, the crew experienced a significant malfunction with the left engine. System monitoring revealed that the Interstage Turbine Temperature (ITT) had risen above 900°C, while the engine torque dropped to zero. The crew followed emergency procedures and successfully secured the left engine. Shortly after this, the crew noted brief, intense vibrations occurring in the right engine. At 01:43:48 hours, the co-pilot declared an emergency, approximately 25 nautical miles from the destination.
The aircraft proceeded on an ILS approach to runway 2lar. During the final approach, the aircraft began to veer left and descend below the established glidepath. The crew decided to execute a go-around; however, when attempting to increase power via the right engine, no additional thrust was available. As the aircraft lost airspeed, the crew attempted to compensate using elevator controls.
Witnesses from the airport fire service observed the aircraft's bank angle fluctuating before the landing lights disappeared from view. The aircraft type impacted the ground approximately 100 meters before reaching the threshold of runway 26L. There were 0 fatalities and 0 injuries reported as the crew successfully evacuated the aircraft on their own.
Findings
- The crew experienced a primary failure of the left engine characterized by extreme ITT and zero torque.
- A secondary issue involved vibrations in the right engine.
- The inability to increase power from the right engine during a go-around attempt prevented the aircraft from maintaining the necessary flight path, leading to the impact.
