I imagine that engine would flip the airplane over in short order if you unloaded the wing and torqued it. I don't have a dog in this fight (sorry PETA) but I think the whole torque roll thing is generally oeverstated. While I don't have any TBM or Mustang time, I do fly a 1400hp single and a "torque roll" just doesn't play into the equation. Robert
We just had this discussion at Simcom. Torque roll is a real possibility when the airplane is slow and you firewall the throttle like in a go around. However, training combats it and it isn't driving the accident statistics.

Don, I know where your mind is going..... Sub 1 mil for a great, newish TBM, hmmmmmm.

We have a voluntary pilot safety program at POPA. Involves a mid-year flight training event like a flight review (in addition to annual recurrent training) plus 2 wings credits for the ground portion. Pretty simple. We have tried different incentives in addition to the insurance discounts, but unfortunately participation is low. If industry or regulations requires additional training, that would decrease participation in GA which would drive up costs. At some level, we must accept the risks and safety records.

It is getting harder and harder to not justify a type rating for turboprops. The turboprop is every bit as complex, if not more so, than the jet. Private and insured operators are getting insurance mandated yearly type training anyway, so it wouldn't be that much of a burden to the owner/operators to do it. Some countries already do this for turboprops and have a far better accident record than the US. Having a bunch of SFARs is stupid, let's normalize the turboprop training requirements. Mike C.

We're talking about planes that cost $millions and operate at about $1K/hour. Do you really think a $3K recurrent training session would curtail usage? Mike C.

Right. Most are lack of basic airmanship capability.

We have tried different incentives in addition to the insurance discounts, but unfortunately participation is low. If industry or regulations requires additional training, that would decrease participation in GA which would drive up costs. At some level, we must accept the risks and safety records. Voluntary works well for those that volunteer. Unfortunately, as Doug Ranz has pointed out 80% of pilots think they are above average. Put the typical personalities who can afford it into an airplane that costs millions and you tend to have above average ego sometimes not accompanied by self critical understanding of capability. These people don't volunteer. So when they kill themselves they hurt lots of others.
Part of what has made the Cirrus program work is that while it's voluntary in many cases you have no choice. For example, when I purchased my airplane new I was required to take the Cirrus initial training course (which had very extensive ground school requirements before I showed up) and pass all the required checks to the commercial pilot and/or IFR check ride standard in order to get a completion certificate. Without the certificate my insurance company would not allow solo flight. For others, purchasing used, the social pressure in the Cirrus pilot community (COPA) had the beneficial effect of getting a lot of pilots who might have otherwise not participated to do so.
If the accident rate was meaningfully impacting sales Daher would be far more aggressive in developing a better set of training regimes. They might even be willing not to sell an airplane to an unqualified pilot (right). Instead of tackling the issue in the most effective way through training they are adding doo dads (which I'm not knocking as they help) to give prospective buyers the illusion of easily obtained safety. My essential point is they ought to do both.

Anyone who can't afford, or objects to affording, that kind of recurrent cost should stick to flying airplanes with less capability. For the record though, Simcom recurrent is $4k plus travel and transportation costs. So for me, flying my own plane there (which I enjoy) add another $7,000 for flight, hotels and meals.

I don’t believe there is anything inherently dangerous or unique about a TBM. Therefore, I don’t think a SFAR makes sense. It’s just a higher performance airplane, and it probably pushes some pilots beyond their capacity. However, I think a formal type rating would fix it.
I know a few Mustang pilots that really struggled getting their type ratings. They just didn’t have the skill set developed to perform within the tolerances of the program. They had to step back, take additional training, and learn how to fly safely by the book. A couple of them took a year to finish. How have they done since? Just fine. They do their annual recurrents just like everyone, and their self assessment and self awareness is much better than it was before. A humbling experience for them.
I mention this because I can envision guys like that buying a TBM instead of a jet, possibly to avoid the type rating, and getting themselves into trouble. The performance profiles aren’t much different, and the required airmanship isn’t much different either. It doesn’t make sense to excuse one airframe from a type rating and requiring it for the other. Undoubtedly, there would be tremendous resistance from the SETP owners and manufacturers, but if they really want to improve their safety to jet standards, that’s the path to take.

Clint - I spent time in the TBM world and now the Mustang world - I think you hit everything on the head perfectly with one exception - I firmly believe the TBM is a more demanding and difficult aircraft to fly than the Mustang. I have instructed a fair amount in both, pilots and non pilots (companion training). The TBM sales people actually promote the fact that no type rating is required. If a type rating were required at a 142 school such as FSI or CAE the accident rates for the TBM would plummet.

I'm outside that window and cannot make it to SnF this year. anyone know how to get the discount on the initial? it's substantial- like 30% !

You just have to schedule it within 12. I’d just call them up and ask. Still pricey for 2 days and 5 hrs of sim.
