Partenavias
At the risk of further thread drift........................
The discussion at this point centers around the possibility or probability of carburettor icing as a factor in the Islander accident. The Islander came equipped with either 260 hp carburetted engines, or 300 hp injected engines (or Allison 350 turbines), and apparently this one was carburetted.
In support of the carby ice possibility, two Partenavia apparent double engine failures have been cited as due to carby ice.
The P68B, P68C and P68 Observer aircraft were delivered with Lycoming IO-360 engines. Note the 'IO'. That's injected, not carburetted. The P68TC featured a turbocharged, injected engine from the same manufacturer. Various other engine / airframe combinations were mooted or marketted, but without much success. Before anyone asks, the P68A refers to the several pre-production aircraft.
Another poster has observed that during his conversion onto the Partenavia, he was advised that the (cooling) air intakes (located on the front of the engine cowling) were very prone to blocking with ice. This may or may not be so, but is in any case irrelevant to the Islander discussion, with different engines and cowls, and it's not carby icing.
The standard Partenavia, as delivered, does not suffer from carburettor icing. It doesn't have carburettors! (or carby heat, or carby heat selectors )-: )
Xploy Ted,
I'm sorry to hear that your friend and his passengers perished in a Partenavia accident. Like most light twins, it is not a forgiving aircraft to operate in adverse conditions. You can be assured though, that their demise was not due to his error in not selecting carby heat.
Now, can we get back to discussing Islanders please!
