16 more Chinooks for the RAF
John
I'm afraid I don't know anything about the S-61 agreement.
The historical problems I referred to are unconnected to FMS. Boeing were severely criticised after a series Chinook accidents, by both the RAF Director of Flight Safety and our Air Accidents Investigation Branch. So much so, in 1992 DFS reported the company were unfit to act as a Design Authority. The AAIB reported that there was a distinct lack of expertise at the company, particularly on equipment they did not actually manufacture. It is one thing to contract out (in that case) the manufacture of control actuators, but that does not mean you don't employ someone who understands what they do and how they integrate with the rest of the aircraft. Similarly, at the same time it had no-one who understood the operation of safety critical software, yet had certified the aircraft as safe.
That is not to say they never make good products. But the same mistakes are being repeated. I could be talking about 737 MAX!

Tecumseh, I’m not in a position to comment on Boeing’s accidents with the CH-47 in the period after they entered service in the UK. For after market add-ins,one has to be careful when it comes to parts of the basic lift, drive and control systems. All I'm saying is that some rotary wing design and operating environments are unique. We didn’t have any actuator issues with the Comanche FBW actuators, but initially did with the Canadian MHP tail rotor actuators, which were sourced from a company serving the fixed wing community.
