AD NUMBER: 2005-19-05
MANUFACTURER: Aerospatiale (CORRECTION) SUBJECT: Airworthiness Directive 2005-19-05 SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for certain Aerospatiale Model ATR42-500 airplanes.
This AD requires inspecting for correct installation of the
fastener that attaches the ground braids on the elevator, modifying
the forward bonded assembly of the elevator control rod, and
corrective action if necessary. This AD results from a functional
test of the elevator trim tab control rod of the leading edge,
which showed that, in a full-up elevator condition with the tab
fully down, interference could occur between the tab control rod
and the forward edge of the lower skin of the elevator. We are
issuing this AD to prevent discrepancies between the elevator trim
tab control rod and the forward edge of the lower skin of the
elevator, which could result in reduced control of the elevator and
consequent reduced controllability of the airplane.
