Latitude Aviation is proud to bring to market N789RP, which is a 1976 Cessna 421C based outside of Baltimore at KDMW. N789RP is owned by several BeechTalk members in a partnership.
N789RP has 7679 total time and 0 SMOH on the left engine (being installed as I type this post) and 1063 SMOH on the right engine. It has 483 SPOH as well. In a former life it was an air ambulance so its paperwork and maintenance pedigree is fantastic. And it's useful load is a whopping 2459 pounds!
The panel is incredible with its Garmin G600 TXi, STEC 3100 autopilot, dual GTN 750's, GWX 75 radar, GTX 345R, GMA 35c, ESI 500, and EDM 790.
Other upgrades include 1 nacelle locker fuel tank (28 extra gallons), VG's, Premiere Aviation Speed Covers, and R134A air conditioning upgrade.
The paint was redone in 2019 and the interior was redone in 1996. The condition of each is consistent with its age.
There is some damage history which is noted in the spec sheet below as well.
I have included the full spec sheet below which has a Dropbox link that will take you to the logbooks, high-resolution photos, FAA 337's, and some other materials. Please email, text, call, or PM anytime discuss this awesome example of a 421C. Thank you!
