N821SY

This article covers airframe N821SY, a Boeing 737-8FH (737-800) completed in 2014 with manufacturer serial number 39952. The aircraft is registered in the US and is held in trust by UMB BANK NA TRUSTEE, a corporate trustee located in Salt Lake City, UT, US; public records list this entity as the owner. As a single-airframe summary, N821SY has a high-density single-class cabin and is typically documented in leasing and trust registries rather than with a single long-term commercial operator. No separate commercial operator or unique incident history is published in the supplied data.

N821SY is outfitted with a single-class high-density passenger cabin configured to approximately 186 seats (Y186), consistent with high-capacity short- to medium-haul airline service. The airframe’s mission profile, given its seating density and a range of 3,115 nm with cruise speeds near 514 kts, aligns with high-frequency domestic trunk routes and regional international sectors within the continental range. Maintenance considerations for this specific aircraft follow the Boeing 737-800 family practices and CFM56-7B engine shop visit cycles; its trustee ownership suggests the airframe may be managed for lease, remarketing, or asset-backed financing rather than owner-operated services. Avionics fit and interior detail are not published in the supplied data.

The Boeing 737-8FH (737-800) of which N821SY is an example occupies the high-density narrowbody market niche, balancing capacity (about 186 seats) and range (3,115 nm) for airlines seeking efficient short- to medium-haul operations. Its competing models include later-generation narrowbodies and single-aisle types offering similar seat-mile economics; residual value and lease demand typically reflect the airframe’s age (2014) and engine family (CFM56-7B). For asset managers and buyers, considerations include CFM56-7B maintenance status, interior high-density configuration, and the aircraft’s trustee ownership structure which can influence remarketing timelines.
