Twin Commander Aircraft has launched a training program for technicians who will perform the inspections detailed in Service Bulletin 241. It is for the hardware that attaches the fuselage to the wing main spar in the 690, 690A and 690B, with the exception of certain serial-number 690As and Bs that have already been inspected and modified. Later-model Twin Commanders, the 690C/D and 695A/B, have a different attachment design and are not affected. “The service bulletin inspection requires a great deal of skill and attention to detail to be performed properly,” said Twin Commander Aircraft president Matt Isley.
