The new Lightweight Ceiling Panels replace the existing OEM interior ceiling panels with quality, engineered aerospace grade design and material. The DART panels are 40 lbs lighter than conventional OEM panels, translating into extra payload (passengers, cargo, and/or fuel). Furthermore, our design splits the center portion into 3 individually removable panels for improved access for maintenance. The side panels are hinged to drop down for easy maintenance. The streamlined construction provides more headroom while also improving ventilation and distribution for center passengers. *Includes 3 center panels, 2 side panels. Includes speakers, LED lighting, air conditioning tubing, and anodized aluminum air vents. Does not include temperature sensor p/n 362150V01251 or emergency lights p/n 2LA455115-26. Does not include airframe mounted hinges. Price is per aircraft.
