CABIN AIR PLENUM (P/N 12029-003) - As Removed

The 12029-003 cabin air plenum collects and distributes conditioned air throughout the aircraft cabin. Positioned between fresh-air or environmental control system sources and cabin diffusers, this pneumatic component maintains uniform airflow pressure and velocity to downstream ducting. Typically constructed from aluminum or composite materials, the plenum reduces turbulence and noise while ensuring balanced ventilation to multiple cabin outlets.

Installation follows the applicable Aircraft Maintenance Manual specifications and requires verification against the Illustrated Parts Catalog for your aircraft model.
