|This fresh air vent system replaces the forward cabin vent. It features durable Wemac air vents which deliver full/partial closure, directional control, and postive shut-off. Focused air control improves cabin comfort. All metal construction. Completely replaces the old style, plastic overhead fresh air vents in most Cessna 210 aircraft. Includes the forward center, and aft systems. STC approved.|
Per the vendor, if it were a mechanic doing the install it would probably take 4-7 hours. If a normal individual were installing it would probably take a day or two. It really depends on how well the installer knows the airplane because most of the interior needs to come out.
