Comp arf Superextra crash
Hi guys,
A friend of mine crashed his superextra yesterday after only ten flights. The right aileron was suddenly torn off the right wing, while flying at low speed in a straight line at medium altitude. It was clear this failure was not caused by flutter since the gear was all brand new and made with the supplied hardware from the kit. The servo’s running the ailerons were HS5645MG’s @ 6V. After investigation of the crash site it was clear the crash was caused by a production error of the aileron hinge. The aileron was torn off backwards beginning at the hinge. ( see added pictures)
Does anyone has had the same problem? He would like to have a replacement for this plane since the crash was clearly not his fault. I personally think there is a need for a glasfibre/epoxy reinforcement to prevent crack initiation and propagation. I don't know if this sort of production error has already occured, but if yes I think comp arf should reconsider there production methods concerning these hinges.
Who should I contact at comp arf concerning this matter?
any help would be greatly appreciated. !
Best regards
