N137CG

This article covers airframe N137CG, a Boeing-built narrow-body originally manufactured in 1995 with manufacturer's serial number 27700. The airframe is a converted firefighting tanker based on the Boeing 737-3H4 (737-300 Fireliner conversion) originally produced by The Boeing Company. It is registered in the US and is recorded as owned by CSC DELAWARE TRUST CO TRUSTEE (a corporation) of Wilmington, DE, US. Operator/home base detail, registry action chronology, and formal valuation or condition summaries are not published for this specific registration.

The airframe carries a purpose-built cabin conversion featuring a firefighting tank installation; the tanked interior can be restored or reconfigured to carry up to approximately 72 passengers or firefighters when fitted with seats. Specific avionics fit and mission equipment lists are not published for this registration; however, the primary mission profile is the fixed-wing multi-engine firefighting role enabled by the conversion. Operator base and routine route schedules are not published; maintenance considerations for this individual airframe would focus on inspection and upkeep of the tank installation, delivery plumbing, and associated airframe modifications required by the firefighting role.

This airframe belongs to a converted derivative of the Boeing 737-300 family, adapted specifically for aerial firefighting tasks and retaining the type’s original turbofan propulsion configuration (CFM56-3B-1) and commercial-origin fuselage. Its performance figures—cruise 430 kts, range 2,255 nm, and service ceiling 37,000 ft—define a niche suitable for rapid-response and regional tanker assignments rather than long-haul passenger transport. Buyer interest, charter suitability, and resale considerations for this airframe are driven principally by its conversion status, calendar age (1995) and serial lineage (27700), which affect regulatory recertification, specialized maintenance, and residual market demand.
