PLACARD ENGINE OIL CJ2

The 6391200-21 is a genuine Textron Aviation placard engine oil cj2 — a marking that identifies a control, limitation, or servicing point on the aircraft. It fits the Citation CJ2 or CJ2+. It carries an export classification of ECCN 9A991, weighs 0.01 pounds, and measures 1.4 (L) x 3.8 (W) x 0.15 (H) Inches. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the 6391200-21 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common. Placards and markings convey required limitations, identifications, or servicing information, so correct wording and placement are part of the aircraft's approved configuration. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
