NTSB Safety Recommendations A-10-132 through -135
************************************************************
The National Transportation Safety Board recommends that the
Federal Aviation Administration do the following:
Require Apical Industries Inc., to redesign the emergency
float system for helicopters such that the mid and aft
floats can no longer be interchanged and installed
incorrectly to the port fitting. (A-10-132)
Once the redesigned Apical emergency float system described
in Safety Recommendation A-10-132 is available, require
operators of all helicopters currently equipped with Apical
emergency float systems to install the redesigned system.
(A-10-133)
Require operators of helicopters equipped with Apical
emergency float systems to immediately conduct a one-time,
two-person, visual inspection to ensure that the hoses from
the mid and aft floats are properly installed to the port
fitting. (A-10-134)
Until the redesigned Apical emergency float system is
installed as described in Safety Recommendation A-10-133, at
every maintenance activity that requires disconnection of
the hoses, require a two-person inspection of the re-
installation of the hoses from the mid and aft floats to the
port fitting and to sign a maintenance checklist attesting
to proper installation. (A-10-135)
