Dassault Falcon

FAA Airworthiness Directive Logo
 
A new amendment supersedes an existing Airworthiness Directive (AD), applicable to all Dassault Model Falcon 2000 series airplanes, and certain Dassault Model Falcon 900EX and Mystere Falcon 900 series airplanes. That AD currently requires repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action if necessary. This amendment removes Model 900EX and Mystere Falcon 900 series airplanes from the applicability of the existing AD. For Model Falcon 2000 series airplanes, this amendment also adds certain repetitive measurements, deletes certain repetitive measurements, and extends the interval for repetitive replacement of certain jackscrews. The FAA says this action is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent jamming of the flap jackscrews during the approach to landing, which could result in inability to move the flaps or an asymmetric flap condition, and consequent reduced controllability of the airplane.

This amendment becomes effective Jan. 6, 2003.

Raytheon Hawker Jets

A new FAA document proposes the adoption of a new AD that is applicable to certain Raytheon Model Hawker 800XP and 800 (including variant U-125A) airplanes. This proposal would require a one-time inspection to identify the bolts installed at certain locations in the wing or fuselage, and corrective actions if necessary. The FAA claims this action is necessary to prevent failure of certain attachment bolts due to manufacturing discrepancies, which could result in reduced structural integrity of the airplane, and loss of system function for flaps, controls, and landing gear. Comments on this proposal must be received by Jan. 16, 2003.

Eurocopter

An amendment adopts a new AD for the specified Eurocopter France (ECF) model helicopters that requires inspecting the 9-degree frame (frame) for the correct edge distance of the two attachment holes for the reinforced latch support and for a crack, and repairing the frame if necessary. This amendment is prompted by the detection of a fatigue crack on the left-hand side of the frame during maintenance. The FAA claims the actions specified by this AD are intended to prevent failure of the frame due to a crack at the latch support, loss of a passenger door, damage to the rotor system, and subsequent loss of control of the helicopter. This action becomes effective Jan. 3, 2003.
