A 1980 Beechcraft King Air B100 hangared in Gallatin, Tennessee has been designated a top pick by FLYING Magazine's AircraftForSale platform, with the listing's primary selling point rooted in its continuous operation under FAA Part 135 commercial air carrier standards. The airframe carries 13,975 total hours and was most recently put through Phase 3 and Phase 4 progressive maintenance inspections in November 2025 — the most comprehensive interval in the King Air's four-phase cycle, typically occurring every 800 hours or 24 months and effectively resetting the maintenance clock. The aircraft is powered by two Garrett TPE331-6-252B turboprop engines, each rated at approximately 1,100 shaft horsepower, with the left engine at 556 hours since hot section inspection and the right at 1,458 hours since HSI — both well within the TPE331's recognized 1,800-to-3,600-hour hot section interval. Propellers were overhauled within the last 1,200 hours. The package is being marketed as turnkey, meaning a prospective operator could theoretically absorb the aircraft into a commercial or business flight operation without immediate unscheduled maintenance exposure.
The Part 135 pedigree attached to this airframe carries specific and quantifiable value for professional operators evaluating used turboprops. Under Part 135, every inspection, discrepancy, and corrective action is subject to FAA Principal Operations Inspector oversight and audit, creating a documentation trail that is structurally more defensible than Part 91 maintenance records alone. For a buyer intending to operate under Part 135 or Part 91K, or even for a corporate flight department seeking favorable insurance underwriting, an aircraft with a continuous 135-maintained history eliminates the due-diligence burden of reconstructing maintenance pedigree from potentially fragmented private logs. The completion of Phase 4 — which encompasses wing bolt torque verification, fuel system inspections, control surface checks, and engine accessory reviews — in the months immediately preceding listing means the new owner is purchasing into the early stages of a fresh maintenance cycle rather than approaching a costly inspection interval.
The King Air B100 occupies a narrow but durable niche in the turboprop market. Produced only from 1980 to 1983, with roughly 92 units built, the B100 sits between the earlier King Air 100 and the stretched, more capable King Air 200 that ultimately dominated the line. Its Garrett TPE331 engines distinguish it from the PT6A-powered King Air 200 and 350 variants — a distinction that matters operationally. The TPE331 is a fixed-shaft, reverse-flow design known for high power output at altitude and exceptional reliability, but it demands pilot familiarity with its different power management characteristics compared to the free-turbine PT6A. Maintenance infrastructure for the TPE331 is slightly less ubiquitous than for PT6A platforms, a factor operators must account for in route planning and MRO contracting. At a projected 2026 market value in the $800,000 to $1.2 million range depending on avionics configuration, the B100 remains competitive for small charter operators, fractional programs, and corporate flight departments seeking a pressurized cabin with 25,000-foot cruise capability and a 1,500-nautical-mile range at a price point well below current King Air 200 or 350 offerings.
The broader significance of this listing reflects a persistent market reality in business and charter aviation: well-documented, commercially maintained turboprops command premium positioning because they reduce acquisition risk in an environment where pre-purchase inspection costs, post-acquisition airworthiness directive compliance, and insurance premiums represent substantial and often underestimated ownership costs. For Part 135 certificate holders looking to add fleet capacity, acquiring an aircraft already compliant with commercial standards — rather than elevating a Part 91 airframe to that standard — eliminates the transition maintenance costs and operator manual revisions that can add months and significant expense to fleet expansion. The growing visibility of platforms like AircraftForSale, which surfaces detailed maintenance data and operational history alongside listing price, also signals a broader shift toward transparency-driven transactions in the used aircraft market, particularly for turbine equipment where buyers are increasingly sophisticated and maintenance-literate.
