Public records available for this specific tail indicate the current ownership and registration state; previous owners and detailed registry transaction history are not published in the supplied data. Condition and formal valuation figures for this specific airframe are not published in the supplied data.

This airframe is outfitted in a standard passenger layout configured for single-class operation of up to 149 seats; the exact interior specification under the current owner is not public. Avionics fit and specific onboard systems are not published in the supplied data, so detailed equipment or retrofit status cannot be stated here. Typical mission profiles for a 737-300 series airframe of this configuration include short- to medium-haul scheduled or charter passenger services within its published range and cruise capabilities. The operator base associated with the registered owner is Pasadena, California, which would typically support operations within domestic U.S. and nearby international sectors consistent with the airframe’s range and performance.

The Boeing 737-3H4 belongs to the 737 Classic family, commonly equipped with the CFM56-3 series engines and serving in high-density single-class roles. With a cruise speed of 430 kts and a ceiling of 37,000 ft, this airframe fits the performance niche for short- to medium-range trunk routes where payload and frequency are prioritized over long-range capability. Market considerations for this model typically emphasize engine maintenance cycles for the CFM56-3B1 engines, availability of used airframes for conversion or secondary operators, and resale demand driven by regional or charter operators seeking higher-seat-count, lower-capacity equipment.
