MANUFACTURER: Avions Marcell Dassault SUBJECT: Airworthiness Directive 2005-07-23 SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for all Dassault Model Falcon 10 series airplanes.
This AD requires revising the Limitations section of the airplane
flight manual (AFM) to include a statement prohibiting flight into
known or forecasted icing conditions, and installing a placard in
the flight deck.
In lieu of the AFM revision and placard installation, this AD
allows identifying the part number of each flexible hose in the
wing anti-icing system, performing repetitive detailed inspections
of each hose for delamination, and performing corrective actions if
This AD is prompted by a report of delamination of the internal
wall of a flexible hose in the wing anti-icing system. We are
issuing this AD to prevent collapse of the flexible hoses in the
wing anti-icing system, which could lead to insufficient anti-icing
capability and, if icing is encountered in this situation, could
result in reduced controllability of the airplane.
