Jag vet att vissa tillverkare både säljer kit och färdig version av sina flygplan. För en rättvis jämförelse av olycksfrekvensen undrade jag:
Vad är olyckshastigheterna för kitbyggda flygplan vs normala flygplan av samma modell?
Är hembyggnaderna mindre säkra än företaget färdiga flygplan?
Australian Transport Safety Bureau gjorde en rapport med titeln:
Denna rapport täcker specifikt detta och konstaterar att olycksfrekvensen var tre gånger högre i kit byggd -vs-liknande fabriksbyggda flygplan:
What did this report do
The ATSB investigated the safety history of amateur-built aircraft in Australia through analysis of accident data held in the ATSB’s occurrence database from 1988 to 2010. Comparisons were made between accidents involving amateur-built aircraft and those involving similar factory-built aircraft to help identify whether the rate and types of accidents differed between these two groups of aircraft.
What the ATSB found
Amateur-built aircraft had an accident rate three times higher than comparable factory-built certified aircraft conducting similar flight operations between 1988 and 2010. The fatal and serious injury accident rate was over five times higher in amateur-built aircraft, in particular due to relatively more serious injury accidents. The pilots of amateur-built aircraft involved in accidents were significantly more experienced overall than factory-built aircraft accident pilots. However, they were significantly less experienced on the aircraft type that they were flying at the time of the accident.
Over half of the accidents were precipitated by mechanical events, which were mainly complete or partial engine failures. Following the amateur-built phase one test period, mechanical failures were still significantly more common when compared with factory-built aircraft. A quarter of accidents were from loss of aircraft control. Structural failures were not common precursors in amateur-built aircraft. Collision with terrain and forced landing accidents were more frequent in amateur-built aircraft. Collisions with terrain, hard landings, and runway excursions were more likely to result in a serious injury from an amateur-built aircraft accident than for factory-built accidents.
Å andra sidan säger EAA att homebuiltflygplan har en olyckshastighet på mindre än 1% högre än den allmänna flygflottan i deras Vanliga frågor , men det jämförde inte homebuilt till fabriken byggd i liknande modeller:
How Safe Are Amateur-Built/Homebuilt Aircraft?
Studies by FAA and the National Transportation Safety Board (NTSB) show that Amateur-Built/Homebuilt aircraft have an accident rate less than one percentage point higher than the general aviation fleet. In fact, the accident rate for Amateur-Built/homebuilt aircraft is dropping. The total number of registered homebuilt aircraft is increasing by about 1,000 per year, while the total number of accidents has stayed virtually the same. Another good barometer of safety is insurance rates. Companies that insure both homebuilts and production aircraft charge about the same rates for owners of either type of airplane. That indicates a similar level of risk.
