COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Fokker F50 (F27 Mk 50) Series Aeroplanes
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
AD/F50/81 TCAS Antenna Structural Provisions 2/2001
Applicability: Model F.27 Mk. 050 aircraft, serial numbers 20168, 20171, 20177, 20180, 20181,
20185 through 20188, 20193 through 20195, 20198, 20199, 20207 through 20209,
20215 through 20219, 20221, 20233, and 20271.
Requirement: Reinforce the affected structure in accordance with the Accomplishment Instructions of Fokker SB F50-53-054, dated May 1 2000.
Note: RLD AD 2000-152 refers.
Compliance: Within the next 12,000 flight cycles after installation of the TCAS antenna.
This Airworthiness Directive becomes effective on 22 February 2001.
Background: During a product review, Fokker Services discovered that the structural provisions for the installation of the Traffic Collision Avoidance System (TCAS) top antenna do not meet the pertinent requirements. This condition, if not corrected, could result in reduced service life of the affected structure. This Directive requires installation of an external doubler under the antenna.

The above AD is notified in the Commonwealth of Australia Gazette on 24 January 2001.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide the legal framework for ensuring the safety and efficiency of civil aviation in the country. One particular aspect of these regulations is the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA). The AD for Fokker F50 (F27 Mk 50) series aeroplanes, specifically AD/F50/81, was introduced to address an identified safety issue concerning the structural provisions for the installation of the Traffic Collision Avoidance System (TCAS) top antenna on certain Fokker F50 aircraft. This directive aims to ensure the safety of these aircraft by mandating the reinforcement of the affected structure, as detailed in Fokker Service Bulletin F50-53-054 dated May 1, 2000. The AD became effective on 22 February 2001, requiring compliance within the next 12,000 flight cycles following the installation of the TCAS antenna.
Scope and Application
The Civil Aviation Regulations 1998 (CAR 1998), specifically Part 39 - 105, addresses the requirements for maintaining the airworthiness of aircraft in Australia through Airworthiness Directives (ADs). This regulatory framework applies to particular Fokker F50 (F27 Mk 50) series aeroplanes, specifically those with the serial numbers listed in the directive. The AD mandates that the action outlined in the requirement section, which involves reinforcing the affected structure according to specified instructions, be carried out within a stipulated timeframe. This directive applies to the mentioned Fokker F50 aircraft and is issued by a delegate of the Civil Aviation Safety Authority (CASA) to address a specific safety issue identified during a product review. The AD becomes effective on the date specified, and compliance is mandatory for the safety of the aircraft.
Key Provisions
This Airworthiness Directive (AD) (AD/F50/81) issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) is applicable to specific Fokker F50 (F27 Mk 50) series aeroplanes with particular serial numbers (subsection 105.011(1)). The AD mandates that the affected aircraft have their Traffic Collision Avoidance System (TCAS) antenna structural provisions reinforced in accordance with Fokker Service Bulletin F50-53-054, dated May 1, 2000 (subsection 105.011(2)). This reinforcement must occur within 12,000 flight cycles following the installation of the TCAS antenna (subsection 105.011(3)). The directive was issued on 12 January 2001 and became effective on 22 February 2001 (subsections 105.011(4) and (5)).
The AD imposes several obligations on the entities it governs. Primarily, it requires the reinforcement of the TCAS antenna structural provisions on the specified Fokker F50 series aeroplanes. This reinforcement must be carried out in accordance with the instructions provided in Fokker Service Bulletin F50-53-054, dated May 1, 2000. Furthermore, the reinforcement must be completed within 12,000 flight cycles after the installation of the TCAS antenna. These obligations are designed to ensure that the affected aircraft maintain their airworthiness and comply with safety standards.
Breaches of the AD may result in significant consequences. While the specific civil or criminal penalties are not detailed in the text, it is understood that failure to comply with an AD can lead to penalties under the CAR 1998. Such penalties can include fines, suspension or revocation of aircraft certificates of airworthiness, and potential criminal charges for non-compliance. The exact penalties may vary depending on the severity and circumstances of the breach, but they are intended to enforce compliance with airworthiness standards and ensure the safety of aviation operations.
