I operated AS355s for many years and flew AS355F, F1, F2 and N without any major problems, both in Europe and Nigeria. All of the models have some electrical problems if left out in the rain, be it in cold northern climes or hot tropical ones. The aircraft is certified to operate in either Performance Classes 1 or 2 and single engine performance is perfectly acceptable for an aircraft of its age and weight. I have operated it in the EMS, law enforcement, offshore, corporate, VIP, charter, pipeline survey, filming and training roles and it's one of my favourite twins. Many years ago when I was working in UK we sold one to a police force and carried out flight trials to have it certified for a modified Class 1 profile at slightly reduced weights for an area with a smaller than certified accel/stop distance. It was also certified by the CAA for a substandard rooftop for Robert Maxwell (as his helipad was below RFM criteria). If I weren't supposedly too old for single pilot operations

, I'd be flying it still if I could
