Allen recommended the CJ2+ for my mission before compared to the Citation II. Unfortunately, the purchase price is a bit more than I want to stretch to. The Williams engines sure seem to shine compared to the original Pratts. I'd be a bit hesitant to move to a new engine that hasn't been proven in service for awhile. Does Honda have a lot of these engines currently flying on other planes, or is this a new design?

GE/Honda HF120 engine is a new design. We will see how it works on the HondaJet. It will be years before we know how it really compares to the Wiiliams motor in actual use.

Tepidness is certainly understandable with any new production engine certification such as the HF120. However, I'm pretty confident that a joint effort between two of the worlds largest engine producing companies (GE and Honda) should put any doubts to rest...IMO.

"The HF120 engine's airworthiness certification follows an extensive ground and flight test program that involved 13 engines. During its certification program, the HF120 engine accumulated more than 14,000 cycles and 9,000 hours of testing."

There are singular CJs with engines that have more than 9000 hrs combined on their Williams engines.

This is like ikea testing a drawer to 30, 000 cycles yet my son manages to break it off on the first try

I too would believe the Honda/GE engine will a good bet, turbine engine technology is pretty well sorted out. Honda does not introduce products that are not considered carefully, GE has been churning out jet/fan engines since shortly after Whittle came up with the idea.

Williams has done extremely well considering there engine initially was only intended to make one start and one cycle, it was a cruise missile power plant.

Honda has figured out how to squeeze more efficiency out of their design, at current fuel costs this is what drives the market. This is also what allowed Sam Williams to push Goliath Pratt & Whitney out of the bulk of Citation production.

Well, what are they, about $550,000 per side? I may wait a bit and let others boldly venture where no man has gone before

Alright Dave, but while you're waiting for the HF120 shakedown - I want to see you in an FJ44 modified Citation

Significant engine change is transformational. Airframes are a dime a dozen

Sierra's announcement/choice of the GEHonda HF120 partnership program as a legitimate alternate to the "traditional" engine OEM's caught a lot of the industry heavy weights completely off guard. You could literally see light bulbs going off. Priceless

Attention; hand salute. YES SIR!
Unfortunately, I'm not seeing a lot of those for less than $1.5 million. Guess I'll have to get to work! Maybe the CII will just be a transitional plane

Suggest keeping your kiddo from operating a multi million dollar turbofan jet

I have owned CJ 525 sn 1, 12, 54. Sn 1 was a very good airplane that had a high SB compliance. From looking at the logs,the airframe didn't seem to have bad growing pains. The engines did have some pains. After a few years they got sorted out, but from the looks of the Maint. Logs, the first few years weren't much fun. I do not own a CJ at this time. I do have an Ultra, which I consider to be the most bang for the buck if one needs that capability.

Was S/N "1" the CJ Jim K. The original owner Flew through a thunderstorm and bent the wings?

WHY on earth would Sierra choose BK-Honeywell for the updated CJ avionics?!?
