Can't remember if Pa44 is fuel-injected
It's not (as mentioned by Tinstaffl) - (L)O-360-E1A6D on the PA-44-180.
Survivors reported that the aircraft encountered induction icing conditions
It sounds like the report is using the term "induction icing conditions" rather than "carby icing conditions" as fuel-injected engines are still succeptible to some icing types given the 'right' conditions. ie: it's not referring to any particular aircraft/engine but to the weather at the time.
