I entered autorotation, jettisoned the external load and landed the aircraft. |
I feel that there are several factors that could have contributed to the initial autorotation. |
This profile required the crew to make sure the autorotation RPM was within limits based on environmental conditions and aircraft gross weight. |
During the autorotation the pilot stretched the glide in order to cross a creek to a level landing area. |
No mechanical defects were found that would have contributed to an unsuccessful autorotation. |
The shift to autorotation is perilous, though, because it involves a reversal of the airflow through the blades. |
