Requirement: 1. Check the maintenance records, and determine whether a horizontal stabiliser attachment reinforcement bracket (bracket) part number (P/N) 1232624-1 is installed that was shipped by Cessna from 27 February 1998 through 17 March 2000. If the installed brackets were not shipped by Cessna between 27 February 1998 and 17 March 2000, no further action is required by this Directive.
2. If the above check reveals that affected P/N 1232624-1 brackets are installed, visually inspect the left and right brackets for existence of seam welds along both the lower inboard and outboard wall/flange.
3. If no seam weld is found on the left or right bracket during the Requirement 2 inspection, before further flight, replace with a new or serviceable P/N 1232624- 1 bracket. If the left and right brackets have seam welds along both the lower inboard and outboard wall/flange, no further action is required.
Note: FAA AD 2002-07-01 Amdt 39-12695 refers.

AD/CESSNA 206/55 (Continued)
Compliance: Within 50 hours time in service after 11 July 2002, unless already accomplished.
This Airworthiness Directive becomes effective on 11 July 2002.
Background: The FAA received a report that certain horizontal stabiliser attachment reinforcement brackets were manufactured without seam welds. This Directive specifies actions to detect and replace structurally deficient attachment brackets. Continued use of such brackets could result in structural failure of the horizontal stabiliser.

The above AD is notified in the Commonwealth of Australia Gazette on 19 June 2002.
Overview
The Airworthiness Directive AD/CESSNA 206/55, issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) by the Civil Aviation Safety Authority (CASA) on 28 May 2002, addresses a safety concern related to the installation of horizontal stabiliser attachment brackets on specific models of Cessna 206 series aeroplanes. This directive was introduced in response to a report from the Federal Aviation Administration (FAA) indicating that certain brackets were manufactured without necessary seam welds, which could lead to structural failure of the horizontal stabiliser if left unaddressed. The primary policy objective of this directive is to ensure the continued airworthiness of affected aircraft by requiring the inspection and replacement of deficient brackets, thereby preventing potential safety hazards and maintaining compliance with aviation safety standards.
Scope and Application
This Airworthiness Directive (AD) applies to specific models and serial numbers of Cessna 206 Series Aeroplanes, including P206C, TP206C, P206D, TP206D, P206E, TP206E, U206C, TU206C, U206D, TU206D, U206E, TU206E, U206F, TU206F, U206G, and TU206G within particular serial number ranges, as detailed in the applicability section of the AD. This AD, issued by the delegate of the Civil Aviation Safety Authority (CASA), is applicable across the Commonwealth of Australia, aligning with the overarching regulatory framework of the Civil Aviation Regulations 1998. The directive mandates the inspection and, if necessary, replacement of horizontal stabiliser attachment reinforcement brackets that were manufactured without seam welds, which could pose a risk of structural failure. The directive specifies that affected aircraft must have their maintenance records checked for the installation of certain brackets and, if required, these brackets must be inspected and replaced within 50 hours of time in service after 11 July 2002. The AD does not explicitly mention any exclusions or exemptions, implying that all specified aircraft within the given serial numbers must comply with the directive's requirements. The AD may also be extended or restricted through subordinate instruments issued by CASA, ensuring continuous oversight and safety compliance.
Key Provisions
This Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, pertains specifically to certain models of Cessna 206 series aeroplanes, as outlined in the applicability section (1). The directive mandates corrective actions for an identified unsafe condition concerning the horizontal stabiliser attachment brackets. The directive applies to P206C and TP206C, P206D and TP206D, P206E and TP206E, U206C and TU206C, U206D and TU206D, U206E and TU206E, U206F and TU206F, U206G and TU206G models within specified serial numbers (2).
The directive requires that maintenance records be checked to determine if the aircraft has horizontal stabiliser attachment reinforcement brackets (brackets) with part number (P/N) 1232624-1 installed, which were shipped by Cessna between 27 February 1998 and 17 March 2000 (3). If such brackets are found to be installed and lack the necessary seam welds, they must be replaced before further flight. The specific requirement is to visually inspect the left and right brackets for the existence of seam welds along both the lower inboard and outboard wall/flange (4). If no seam weld is found, the brackets must be replaced with a new or serviceable P/N 1232624-1 bracket. If the brackets already have the required seam welds, no further action is necessary. This action must be completed within 50 hours of time in service after the directive's effective date of 11 July 2002, unless it has already been accomplished (5).
Compliance with this AD is mandatory for the specified aircraft models and serial numbers. Owners and operators must ensure that the maintenance records are checked and the required inspections and replacements are carried out as specified. Failure to comply with this directive could result in the aircraft being considered unairworthy, which could lead to grounding of the aircraft until the required actions are taken. The directive references FAA AD 2002-07-01 Amdt 39-12695, indicating that this is a coordinated action with the Federal Aviation Administration (6).
Breach of the requirements set out in this AD could result in serious safety implications, including the risk of structural failure of the horizontal stabiliser. While the specific penalties for non-compliance are not detailed in the AD itself, non-compliance with CASA directives can generally lead to enforcement actions which may include fines, orders for corrective action, or other administrative penalties as deemed appropriate by CASA. Continued operation of an aircraft in a non-compliant state poses significant safety risks and could also result in criminal charges if it is found to have contributed to an aviation accident or incident.
