AD/J4100/1 State of Design ADs 3/2008 DM

Applicability:	Jetstream 4100 model aircraft, as identified in the individual Airworthiness Directive (AD) listed in Table 1 and 2.
Requirement:	1.    Determine the applicability of the AD issued by the Civil Aviation Authority of the United Kingdom - CAA(UK) listed in Table 1 or the AD issued by the European Aviation Safety Agency - EASA, listed in Table 2.
2.    If it is determined that an AD listed in Table 1 or 2 is applicable and has not been previously accomplished, perform the actions required by that AD.

Note 1:  CAA(UK) and EASA ADs may be accessed via the internet at the following URL:
Note 2:  Australian ADs previously issued in the CAO 105 AD/J41 series, which were based on rescinded CAA(UK) ADs, are no longer effective.  However these ADs will be reviewed and, if necessary, will be reissued in this series.
Compliance:	For Requirements 1 and 2 - Within 30 days after the effective date of this Directive or prior to the issue of a Certificate of Airworthiness, whichever occurs first.
This Airworthiness Directive becomes effective on 31 January 2008.

Background:

The ADs listed in Table 1 and 2 of this Directive require either one time actions for which the compliance date and/or period has passed or multiple inspection/actions until a terminating action has been applied and the compliance date and/or period for the terminating action has passed.  CASA has determined that these ADs may be applicable to recently registered or imported Australian aircraft.  This Directive is issued to ensure all previous State of Design ADs are complied with.

CASA appreciates that, due to date of aircraft manufacture or aircraft configuration and modification status, not all the ADs listed in Table 1 and 2 will be applicable to all Jetstream 4100 model aeroplanes.
