Tandemrotor:
Is there any proof directly linking any 'airworthiness' issues with the cause of the accident on 2nd Jun 1994...
No, because the cause of the accident remains unknown! Why does it remain unknown? Because it has never been thoroughly investigated! It is a matter of record that the Chinook had serious airworthiness shortcomings, the HC1 as evidenced by the CHART report which was not buried sufficiently enough (one copy remaining in the HoC library). The HC2 then added to the Chinook's shortcomings, principally with bad code written for the FADECs. None of this was reviewed by the BoI. Why? The airworthiness of the HC2 was so problematic that BD suspended flying it and pleaded that the RAF (which strangely was already operating it following CAR and RTS) do likewise. The next day was June 2nd, 1994....!
Have you ever asked the AAIB what they thought of this Accident Investigation, Tandemrotor? Extremely rigorous did they say? No? Thought not! This accident cries out for professional investigation. Instead we, the RAF, NoK, everyone, has to rely as usual on Judicial Reviews and Coroners' Reports. Thorough? Yer 'avin a larf, aintcher?
