The State Transportation Commission consists of 15 members including, by virtue of their office, the chairs and minority chairs of the Senate and House transportation committees. The secretary of transportation serves as chair of the commission. The remaining 10 members are appointed to six-year terms by the governor, by and with the advice and consent of the Senate and within statutory requirements for residency, party affiliation and general characteristics, as well as restrictions on holding other state employment. At least one appointee must hold at least a private pilot's license and derive part of his or her livelihood from aviation-related activities or be otherwise actively involved in aviation, and at least two must be members of the board of directors of a transportation authority at the time of appointment. Each member is appointed to represent the interests of the state, not a region or district (Pa. Cons. Stat. Ann. tit. 71, §178). The secretary of transportation is appointed by the governor, by and with the advice and consent of the Senate (Pa. Cons. Stat. Ann. tit. 71, §67.1).
