double flame out in 1999:
got a hint to a German police bo105 which had a double flame out after take off as main tank pumps were never switched on. Successful autorotation but landed in a shallow part of the Elbe river. Busy day with stressful task continuing into night, view on caution lights was blocked due to a gaffa-taped filter for NVG ops which went loose. It was a temp fix to get the ac aloft for a search mission of a missing child.
By any chance, could the view onto the cad in the ec135 have been blocked accidently with some equipment, a map or whatever (- if it was working correctly)? Pilots admitted they had simply forgotten about the main tank pump which I understand was to be switched on after starting the engines with only prime pumps on. Then they simply could not see the caution coming on, and they were not aware of it. P1 flying with NVG's and P2 operating the searchlight - all eyes focused to the outside of the cockpit.
