On November 24, 1999 at an unknown time, a Eurocopter EC-135 helicopter was destroyed after impacting terrain near Basepohl, Germany. Three of the four people onboard received fatal injuries. Weather conditions and type of flight plan filed were unknown.

According to German aviation authorities, the German police were operating the helicopter as a traffic observation flight. The helicopter was observed in a low-level flight, followed by a steep, rapid climb to 120m above the ground, and then a steep descent, which was terminated just above the ground. The helicopter traveled about 150-200m laterally, impacted trees 10m above the ground, and separated the main rotor blades. The helicopter continued an additional 120m and came to rest on the ground.

German aviation authorities examined the helicopter, and revealed no evidence of pre-impact failure to the engines, flight controls, or the main and aft rotor shafts.

The electronic engine control units were retained from the accident site and sent to Hamilton-Sundstrand, in Windsor Locks, Connecticut for further examination.
