N804X

The airframe bearing tail number N804X is a 1999-built Bombardier CL-600-2C10 (CRJ-700), serial number 10002, operated in civil US registry. The airframe is owned by NORTHROP GRUMMAN SYSTEMS CORP, a corporation based in El Segundo, CA, US, and has been adapted from its original airline specification into a corporate/industry testbed role. The airworthiness and registration are recorded under the US registry; notable for this airframe is its transition from standard regional passenger configuration to a test-equipment-modified interior. Condition and valuation specifics are not published in the supplied data.

This specific CRJ-700 retains the standard single-aisle, four-abreast CRJ-700 cabin layout typical of regional airliner specifications (normally configured for 68–78 pax), but N804X has been modified for test equipment, producing a testbed-modified interior rather than a pure passenger layout. Avionics fit follows the typical CRJ-700 installation with Rockwell Collins Pro Line 4, supporting contemporary mission avionics needs and flight test instrumentation integration. Operated by a defense/industrial corporate owner based in El Segundo, CA, US, the aircraft’s typical missions would be corporate-supported flight test, systems development, and instrumentation flights within the aircraft’s 1,434 nm range and maximum operating ceiling of 41,000 ft. Maintenance considerations for this airframe reflect both standard CRJ-700 support and additional systems associated with testbed modifications.

The Bombardier CL-600-2C10 (CRJ-700) occupies the regional jet performance niche with medium-range capability and seating around 80 passengers in standard layouts, but platforms like N804X are commonly repurposed for corporate, test, or special-mission roles. Competitors in the regional/medium business-conversion space include similarly sized regional jets adapted from their airline configurations. Buyers and operators considering such airframes must factor in airframe hours, CF34 engine support cycles, avionics commonality with Rockwell Collins Pro Line 4, and any bespoke equipment installations when assessing maintenance and resale considerations.
