Background: The USCG is planning the sundown of the C‑27J fleet and seeks to assess whether Dowty R391 propellers that have accumulated service on the C‑27J (R391/6‑132‑F/10) can be overhauled and employed on the HC‑130J (R391/6‑132‑F/3). OEM correspondence flags differences in usage spectra, airworthiness limitations, and platform designation/traceability. USCG seeks independent, rigorous industry input on whether a technical, airworthiness, and sustainment-acceptable path exists, with or without OEM endorsement.
