A Aerodyne acabou de lançar um boletim de serviço mandatório colocando todos
containers Icon equipados com Skyhook fabricados até 14/Jan/2011 no chão até
a aplicação do mesmo!
Ocorreram incidentes nos quais Icons equipados com Skyhook tiveram os
tirantes principais incorretamente alojados sob a aba do reserva causando o
travamento da aba e impedindo a extração do tirante durante a abertura do
principal. Estes eventos levaram a uma pesquisa sobre as possibilidades de
travamento dos tirantes do reserva no caso de posicionamento incorreto dos
tirantes do principal. Os testes realizados mostraram que algumas
combinações de componentes (tamanho do container, tamanho do reserva,
comprimento do tirante, dobragem) em Icons equipados com Skyhok poderiam
resultar em travamento parcial (ou total) dos tirantes do reserva. Em uma
situação extrema o paraquedista poderia ficar suspenso pela parte de trás do
ombro e não pela frente.
A Aerodyne está recolhendo todos Icons equipados com Skyhook para
modificação das abas de encaixe dos tirantes.
Se você tem um equipamento Icon equipado com Skyhook entre em contato com a
Aerodyne ou seu rigger. A modificação é mandatória e não é permitido saltar
com o equipamento antes de realizá-la.

SERVICE BULLETIN SB140111
ICON SKYHOOK RISER TUCK TAB
MODIFICATION
Status: Mandatory- Before next jump.
Authority: William D. Legard, President Aerodyne Research, LLC
Identification: Icon containers with Skyhook option manufactured prior to
January 14, 2011.
Background: We have become aware of recent instances in which a Skyhook Icon
was incorrectly packed with the main risers misrouted under the reserve tab
causing a riser cover to not release the main riser when the main was
deployed.
This led us to investigate to update the design to reduce the probability of
the main or the reserve risers not being extracted fully upon deployment in
the case of incorrect placement of the main risers. During these tests we
also found that some combinations of Skyhook Icon components (rig size,
reserve size, riser size, packing configuration) could potentially result in
an incomplete riser deployment when deploying the reserve during a total
malfunction. In a total malfunction, the main risers do not clear the riser
covers, and in some combinations, the reserve riser covers could potentially
lock in place during the reserve canopy deployment. The reserve canopy would
deploy and inflate correctly, but the unreleased risers would cause the
jumper to be suspended from the back of the shoulder rather than from the
front of the shoulder as designed.
Aerodyne has modified and tested an updated riser tuck tab design to prevent
these occurrences and has as a general update and safety measure decided to
implement this design in all Icons equipped with a Skyhook. Aerodyne also
reminds that the packing configuration of the main risers being placed above
the bottom flap is still important to follow also after this modification.
Action Required: Please contact Aerodyne to arrange for your Icon to be
returned and for the updated tuck tabs to be fitted. Once contacted,
Aerodyne will coordinate shipping and the installation of the updated tabs,
all at no cost to the rig owner.
