Glass is correct, and wrong. The OpSpecs do require a qualified SIC, but it is also required per the regs governing all 91K operations. All turbine aircraft operated under 91k must have 2 qualified crewmembers, and the PIC must hold an ATP. If the P180 was operated strictly 135, then only one pilot is needed with a commercial cert
