Some Beech upgrades are taking longer because low time guys are being placed in that aircraft. As a consequence of Colgan (insurance) requirements, it is taking these people a while to accumulate the required mins to upgrade.

Example:
600 Hour pilot placed in Beech.
@ 85 hours / month it would take 16-17 months to upgrade.


Also, Colgan is non-union, so upgrade is not solely based upon senority... rumor has it that they actually have a "list" of people they like.

But hey, even if it is 2 years to upgrade, it sure beats 5+ years at other places.
