There shouldn’t be a second guess in a chopper crash, usually. People working at National Transportation Safety Board in Washington tell that if you write on aviation accidents, you need to let the facts speak and not your vivid conspiracy theoretical imagination. With that being said, there is a possibility from the perspective of multiple scenarios that can be put forward based on logic and precedent.
These can be analysed and verified if the facts fit in any of them but not ever as a concrete conclusion.
In today’s CDS Bipin Rawat Chopper crash, one likely scenario is to wait for any evidence on the voice recorder or messages to ground the control indicating the technical/mechanical issue. This can possibly happen as it is a machine in the ninth year of its service and there are obvious maintenance-related issues that can never be ruled out.
This does not indict any specific section of the helicopter but when a chopper is damaged due to spanner, it was literally left in the works. Back in the year 2015, the Australian Transport Safety Bureau (ATSB) said that a chopper’s rotor blades were damaged during the start-up by Foreign Object Debris (FOD). It is a spanner in their case that had been left behind from the earlier maintenance.
Another incident: In the case of a tragic crash of Alouette III on November 22, 1963, it was carrying three Generals and an Air Marshal in Poonch, it was suspected that it had hit the power lines that clogged the rotors. The Power lines involved here were often unseen against the fog, mist, mounds, hills, blind spots. All of these are a nightmare for any pilot, especially for the ones who are on duty.
Overall, in every three out of four chopper crashes, it is the engine failure that stirs the negative developments. The electrical issues are a common sight of a helicopter malfunction that includes the electrical shorts and electrical component malfunctions.
The bottom line happens to be this: Rather than working on conspiracy theories in any helicopter crash, one that includes the unfortunate crash causing the death of CDS Bipin Rawat today, it would be at the best of the interests to wait for evidence on the voice recorder or messages to ground control. It is too early for conclusions of any sort and these cases can only be seen as possible theories and nothing more.
