About the Lancair PropJet IV
Overview
The Lancair PropJet IV (also called the Lancair IV-PT) is the turbine development of the pressurized Lancair IV-P: a four-seat, retractable-gear composite kit aircraft with a Walter M601E turboprop in place of the piston TSIO-550. On roughly 750 shaft horsepower it cruises near 325 KTAS, the fastest airplane Lancair offered to homebuilders, and it keeps the IV-P’s 5.0 psi pressure vessel, holding roughly an 8,500-foot cabin at FL240. Lancair began flying the conversion in 2000 and offered it to builders shortly after; a Propjet set a 307-knot closed-course speed record in 2002.
As an Experimental Amateur-Built aircraft, every Propjet is individually airworthiness-certificated and reflects its builder’s workmanship; there is no type certificate, and equipment, build quality, and resale vary by airframe. It trades the piston IV-P’s modest fuel bill for turbine simplicity, reliability, and speed, at turbine acquisition and operating cost. Kit production ended in 2012, so buyers shop a finite fleet of owner-built airframes. It asks for a current, well-trained pilot and a turboprop budget.
Key Features for GA Buyers
- Walter M601E turboprop, roughly 750 shp. The Czech-built turbine drives cruise near 325 KTAS on Jet-A.
- 5.0 psi pressurization. Carried over from the IV-P airframe, holding roughly an 8,500-foot cabin at FL240.
- Lower overhaul cost than a PT6. The M601 overhauls for roughly half the price of a comparable Pratt & Whitney PT6A, softening the usual turboprop engine reserve.
- Composite airframe, 125-gallon fuel. Carbon-fiber construction supports long, fast legs at turbine altitudes, with a useful load near 1,500 lb.
Trade-offs
- Experimental Amateur-Built, not type-certificated. Each airframe is individually certificated and reflects its builder’s work; there is no factory POH or type certificate, and insurance, financing, and resale all reflect the experimental category.
- Turboprop operating cost. Jet-A burn and turbine-class insurance put ownership well above the piston IV-P, even with the M601’s lower overhaul reserve.
- High-performance, pressurized airframe. High-altitude flight, pressurization, and a very fast, slick airframe demand recurrent, type-specific training; the Lancair line carries a high accident share in the NTSB record.
- Out of production, finite fleet. Kit production ended in 2012, so parts, support, and comparable airframes come from a limited owner-built pool.
