Description
This Cessna P337H with Riley Rocket conversion with Air conditioning and Robertson STOL represents a rare opportunity to acquire a highly capable, pressurized twin configured for real-world utility and reliable cross-country performance. The aircraft benefits from a combination of recent maintenance, meaningful upgrades, and clean documentation, making it a strong candidate for an owner seeking a ready-to-fly platform rather than a project aircraft. Avionics have been thoughtfully upgraded to provide modern situational awareness and redundancy, including a Garmin 530W WAAS navigator, Lynx NGT-9000D+ transponder with ADS-8 In/Out, traffic, moving map weather, and WIFI, and a Garmin GMA 345 audio panel with Bluetooth and playback functionality. Additional support is provided by a Garmin Gl-106B GPS VOR Glide Slope indicator, Garmin SL60 NAV/COM, and an AV-30 electronic flight instrument, resulting in a clean, functional IFR-capable panel. A standout upgrade is the CIES digital fuel sender system paired with an Aerospace Logic FL202D indicator, providing highly accurate fuel quantity information-an important enhancement for operational confidence in this platform. Performance and handling are further enhanced by the rare Robertson STOL kit, which significantly improves low-speed characteristics and short-field capability, expanding the aircraft's versatility. The aircraft is also equipped with air conditioning, adding comfort for longer flights. Recent maintenance reflects a proactive ownership approach, including turbocharger and wastegate overhaul by Quality Aircraft Accessories, installation of new engine mounts, and low-time propellers. Both engines have received new cylinders with 235 hours, supporting strong compression and near-term reliability. (over 70k in recent improvements). The aircraft also features recent exterior paint, along with replacement of cowl camlocks and inspection panel hardware, contributing to both appearance and serviceability. Logbooks are complete, organized, and professionally maintained, with detailed entries supporting the aircraft's maintenance history. This aircraft has been an outstanding performer for our missions, including regular trips to the Bahamas and extended travel throughout the western United States. Our needs have evolved, and while we will genuinely miss it, we're confident it will serve its next owner just as well.
