Description
The S1389-1 is a genuine Textron Aviation strip felt that provides thermal or sound-damping protection. It fits the Caravan or Grand Caravan EX, Skyhawk, Skylane, and Stationair. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S1389-1 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 Caravan, Skyhawk, Skylane, and Stationair aircraft, reflecting how much structure and hardware these models have in common.
Its rating for heat or sound is what makes an insulation part work, so the correct specified material matters in service. 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.
An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. The Cessna Caravan is a single-engine PT6-powered utility turboprop in continuous production since 1984, valued for its rugged versatility in passenger, cargo, and float operations.
