Lancair IV-P
These figures describe a typical build. Each aircraft of this design was built by its owner, and the one you are looking at may differ.
The Lancair IV-P is the pressurised version of the 1991 Lancair IV: a four-seat composite kit aircraft with retractable gear and a 350 hp twin-turbocharged Continental TSIO-550, first flown in late 1993 and sold as a kit until 2012. It cruises at 291 knots at 24,000 ft, climbs at 3,000 fpm, has a 29,000 ft ceiling, carries 88 usable gallons for about 1,090 nm with reserve and has a 1,060 lb useful load at a 3,200 lb gross weight.
Its accident record is the reason the type is treated with such caution: a 98 sq ft wing, a 62 knot landing stall and little margin at the bottom of the envelope put stalls in about a quarter of its accidents, a 2008 run of twelve fatal accidents brought the FAA's 2010 safety notice on Lancairs and the founding of the owners' organisation, whose type-specific transition course is now the expected route in, and insurers increasingly price the type on whether that training has been done. Pressurisation, turbochargers, retractable gear and a composite pressure vessel each need a shop that knows them. No two IV-Ps are alike: gross weights of 3,200 or 3,550 lb, fuel from 88 to 110 gallons, varying panels and interiors, and some built or converted as turboprops under the same designation, so the aircraft's own flight manual and weight-and-balance are the only valid numbers. Many were finished with heavy factory or professional help, and the build records of such aircraft deserve reading. It needs both the complex and the high-performance endorsement. The owner may maintain it and an A&P signs the annual condition inspection, which is a small saving against the operating cost of a 350 hp turbocharged engine.

- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
