Neither the preliminary accident report nor the Dutch grounding-orders makes reference to the wreckage of PH-4B6. Although for the last three months, Zenair has received no word of new findings from the Dutch Safety Board, factory representatives were recently permitted to inspect the remains of the accident aircraft. Upon careful first-hand examination, we feel sufficient new evidence comes to light that suggests a very different sequence of events than the one proposed by witnesses. The investigation is on-going and we do not know what is currently being considered by investigators, nevertheless, we remain puzzled as to why the official position has not been revised and why the grounding orders remain unchanged.
Three observations in particular seem especially significant. This is what we saw:
1) The leading edge D-cells of both wings of the accident aircraft display remarkable similarities: From root to tip, the front skins of both wings show even and continuous impact damage consistent with straight-on impact. The main landing gear and nose gear strut were undamaged (one wheel fairing actually remains attached). This, along with the nature of the overall damage suggests that the aircraft likely contacted the water straight-on, but more upside down (wheels pointing up) than right-side up.
2) In the area where it passes through the fuselage, the aileron control cable of the wing that supposedly failed in the air is still cleanly threaded through its plastic fairlead which is still firmly riveted (paint is not even cracked) to the fuselage side. The aileron belcranks of both wings are undamaged and still properly secured. In other accidents where a wing was known to have “folded” in flight, aileron control cables ripped through the thin fuselage sides (in the direction of the folding wing) and the aileron belcranks were torn loose from the wing structure.
3) At the rear spar attachment location, the fuselage tab was intact, as was the attachment bolt. It is the rear spar web which failed, but not as we have seen in other accidents where the failure has been attributed to static overload. In this case, the remaining portion of the spar channel and doubler (a washer-like piece still attached under the tight bolt-joint) shows evidence of failure from bending and tearing - rather than from straight “up”, “down” or “out” shear forces.
Considered together (the even crushing of both wings, the absence of aileron cables “ripping” through the aluminum fuselage sides and intact belcranks, and the failure mode of the wing’s rear attachment point), the wreckage seems to tell its own story as to the configuration of the aircraft just prior to impact…
Если коротко - повреждения никак не могли быть вызваны азрушением конструкции, либо элеронным флаттером, который подозревают, но ничем не подтверждают, а исключительно конфигурацией в момент столкновения с водой.
