The AS350 helicopter which took off from Katra helipad in Jammu crashed a few minutes later. An eye witness saw a fire, some saw smoke, bird but the AAIB investigation eliminated everything except the bird. They drew 3 possible scenarios of a bird strike which could permanently to temporarily incapacitate the pilot leading to the accident. Finally, they chose one and closed the investigation.
Some very obvious clues and cues were disregarded. Basic investigative techniques were not used probably, they had already decided the course of action.
After the Ghatkopar King Air C90 accident, I had submitted a technical report and on account of new evidence asked the Civil Aviation Ministry to reinvestigate the accident under clause 15 of the Aircraft (Investigation of Accidents and Incidents) Rules, 2017 by instituting a court of inquiry.
There has been no response from the MoCA. Nevertheless, I submitted the 2nd report and am working on a third one. I hope that there is a collective effort to improve the system and we all benefit from it.
The final report states that the engines were developing power at impact. Compare with the lower image which is from an NTSB accident reports of an AS350 due engine fail. The blade damage pattern are similar.
The report states that the marks on the blades are rub marks but the pattern are overheat marks.
The final report states that the fuel clog indicator pop up was due to impact and the filer was clean. Compare it yourself.
There are many more holes in the report, use the link above to review.
