Max Angle,
Would rather depend, would it not, if that "old Baron" was maintained and flown professionally? Or, are you simply being elitist?
Nothing wrong with higher powered light twin-engined aeroplanes to move one or two crew members from time to time IMHO. Having said this however, these aeroplanes must not be packed to the gills with larger numbers and operated at max weights, or in very poor weather.
And, most important, must be properly maintained. Note for example the 404 concerned. According to the AAIB report, the engine failed due to starter adapter (and related accessory gear) failure. This is a very well known problem area with these geared Continental engines, and is covered extensively by a TCM critical service bulletin which requires careful repetative inspections, which CANNOT be ignored.
