I keep hearing vague allusions to problems with the TH-73. Is someone who knows what is actually happening willing to weigh in?
My suspicion/prejudice is that the aircraft is actually fine but we kneecapped ourselves trying to get cheap when writing maintenance and supply contracts…again.
This is from the student perspective, but the TH73 is quirky and an absolute blast to fly.
The biggest issue from what I understand is the cost. The 57 is comparable to the ole family honda civic with 250K+ miles. Uncomplicated, still works and doesn't cost much to run.
The 73 is a fancy Mercedes. European, expensive and we're still figuring out how to translate to the user manual.
For every part/ maintenance/or damage done to the 73, it costs exponentially more to fix.
From a safety standpoint:
I've never flown the 57, but all my instructors have stated the 73 is a significantly more challenging platform to auto due to the rotor head. Its a lot more high risk to keep students in a safety margin.
There's no "true" ESIS as its not independently powered from the generators.
With the new "spaceballs helmet" they are issuing everyone and the shape of the overhead panel, its very easy to knock into select overhead switches and shut off the electronics.
Other issues like lack of parts/qualified maintainers/ air craft inexperience can workout itself out with time.
In short, the fancy European helicopter costs more than expected and is worrying the longevity/lifespan of the 73.
