Mercer County has been asked whether the commercial airline operating at Trenton-Mercer Airport utilizes any Boeing 737 Max 8 aircraft, which have recently been banned by the Federal Aviation Administration due to mechanical issues. The commercial carrier at Trenton-Mercer Airport does not have that aircraft in its fleet, and the airport is not directly affected by the federally imposed grounding of the Boeing 737 Max 8.
