Event Overview
On December 30, 2000, at approximately 14:45 UTC, a Schweizer 269C helicopter (registration I-MAGB) experienced an incident during takeoff from Modena Marzaglia Airport (LIPM). The flight, a commercial sightseeing trip with a pilot and one passenger, was interrupted shortly after departure. The helicopter executed an abnormal landing that resulted in substantial damage.
Sequence of Events
The pilot reported performing a steep climb to an altitude of about 20 meters (65 feet) when a power loss was felt. In response, the pilot initiated a forced landing onto a grass area parallel to runway 11. During the landing, the helicopter impacted the ground with its ventral section, then tilted to the left, causing the main rotor blades to strike the ground. The pilot stated that the engine was shut off by grounding the magnets. Both occupants remained uninjured.
Investigation Findings
A review of the helicopter's documentation indicated that the aircraft was in compliance with maintenance requirements and was airworthy prior to the flight. Examination of the engine after disassembly revealed no anomalies, failures, or malfunctions that could be linked to a power loss. The flight manual for the helicopter advises against performing takeoffs with low translational speed, as this reduces the likelihood of a successful outcome for the emergency procedure designed for engine failure between 7 feet and 450 feet above ground.
The investigation concluded that the steep takeoff likely induced or favored the power loss experienced when the helicopter was within the height-velocity region for which the flight manual recommends against operating. The evidence suggests a controlled impact with a medium-high vertical descent rate.
