What happened
On an unidentified date, a four-engine aircraft was performing a cruise at 20,000 feet over the region of Bavaria. At approximately 20:09 local time, the aircraft vanished from radar monitoring. The plane subsequently crashed into a field situated north of Nuremberg, in the vicinity of Forchheim. No distress signals were transmitted by the crew before the impact. Upon hitting the ground, the airframe broke apart, and the accident resulted in 52 fatalities with no survivors.
Findings
Official investigations explored several potential scenarios that may have led to the loss of control. One possibility involves a forced descent where the aircraft exceeded its structural limits during an approach or recovery maneuver. Such a descent could have been triggered by a malfunction in the artificial horizon or another critical electrical instrument, leading to an unrecoverable flight attitude.
Another factor considered was an undetected over-adjustment of the electric rudder or aileron trim while the autopilot was engaged. Because the autopilot system lacked a servo-indicator to alert the crew to excessive trim levels, such movements might have gone unnoticed until the autopilot disconnected. Additionally, investigators looked into the possibility of physical incapacitation of the flight crew or an intentional descent prompted by an onboard emergency, such as smoke or fire, which would have subjected the airframe to extreme structural stress.
