Quais são as taxas de acidentes para aeronaves construídas em kit em comparação com aeronaves normais do mesmo modelo?

23

Eu sei que alguns fabricantes vendem kits e terminaram a versão de suas aeronaves. Para uma comparação justa das taxas de acidentes, eu queria saber:

Quais são as taxas de acidentes para aeronaves construídas em kit em comparação com aeronaves normais do mesmo modelo?

As construções domésticas são menos seguras do que a aeronave acabada da empresa?

O Departamento de Segurança de Transporte da Austrália fez um relatório intitulado:

Aeronaves construídas por homens Parte 2: Análise de acidentes envolvendo VH- aviões não construídos de fábrica registrados 1988-2010

Este relatório aborda especificamente isso e descobriu que a taxa de acidentes foi três vezes maior em aeronaves de compilação de fábrica do kit construído -vs- similar:

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.

Por outro lado, a EAA diz que as aeronaves construídas em casa têm uma taxa de acidentes inferior a 1% maior que a frota de aviação geral em sua FAQ , mas isso não compara o homebuilt à fábrica construída em modelos similares:

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.
