N709S

This entry covers airframe N709S, a Boeing airliner delivered in 1997 with manufacturer serial number 28722. The airframe is a Boeing 737-500 (737-5L9) registered in the US and currently owned by SIERRA PACIFIC AIRLINES INC, a corporation based in Tucson, AZ, US. The aircraft’s ownership is recorded to a single corporate operator in Tucson, and its public valuation is listed at $3,250,000. Registry and valuation data indicate an airframe in the mature phase of its service life, reflecting both age-related maintenance considerations and the market position of Classic-series Boeing 737s.

The cabin of N709S is configured for 149 seats, aligning with high-density single-aisle operations typical of Classic 737-500 layouts. Avionics and interior fit details are Not published in the supplied data; however, the airframe’s twin CFM56-3C1 powerplants and mature serial number profile imply routine attention to time-limited components and engine shop visits consistent with an airframe delivered in 1997. Operated from its owner’s base in Tucson, AZ, the aircraft’s advertised 2,400 nm range and 492 kts cruise speed support short- to medium-haul routes and dense regional schedules. Maintenance planning for this specific airframe would prioritize lifecycle items typical of Classic-series 737s, including structural inspections, engine hot-section life limits, and avionics upgrade paths where required.

The Boeing 737-500 (737-5L9) occupies the Classic-series narrowbody niche, offering moderate range and seating for up to about 149 passengers in dense configurations. Competing types historically include regional narrowbodies and early-generation 737 Classics; demand in secondary markets favors operators needing lower acquisition cost units. With a listed value of $3,250,000 and 1997 build year, resale and lease prospects are strongly influenced by remaining airframe hours, maintenance status, and the cost of avionics/engine updates relative to newer generation 737s.
