Applicability:

Models 1900, 1900C and 1900D as specified in the Requirement documents.

Requirement:

1. Determine the applicability of the FAA Airworthiness Directives (AD) listed in Table 1.

2. If it is determined that an FAA AD listed in Table 1 is applicable and has not been previously accomplished, perform the actions required by that AD or later FAA-approved revision.

Service Bulletins approved by the FAA as Alternative Methods of Compliance (AMOC) to the ADs listed in Table 1 are considered acceptable for compliance with the equivalent requirements of this Airworthiness Directive.

Table 1

FAA AD

Title

Effective Date

97-03-01

Right-Hand Exhaust Stacks

14 March 1997

Note: Applicable to model 1900D only.

93-01-16

Stall Warning Vane Housing

8 March 1993

Note: Applicable to model 1900C only.

87-04-24

Elevator Trim Cable System

14 April 1987

Note: Applicable to models 1900 and 1900C.

Note: FAA ADs may be accessed via the internet at the following URL: http://rgl.faa.gov

Compliance:

If a certificate of airworthiness has not been issued for the aircraft - before issue of the certificate of airworthiness.

If a certificate of airworthiness has been issued for the aircraft - before further flight after 19 November 2010.

This Airworthiness Directive becomes effective on 15 October 2010.

Background:

The FAA ADs listed in Table 1 of this Directive require once-only actions for which the compliance date has passed. CASA has determined that these ADs may be applicable to some Australian aircraft. This Directive is issued to ensure compliance with all State of Design ADs.

CASA appreciates that, due to date of aircraft manufacture or aircraft configuration and modification status, some of the ADs listed in Table 1 will not be applicable to any aircraft presently registered in Australia.
