COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Aerospatiale (Socata) TB 200 Series Aeroplanes
AD/TB 200/3 Vertical Stabiliser Forward Junction Doubler 10/99
Applicability: All Model TB200 aircraft.
Requirement: 1. Perform a visual inspection to verify that there is no gap between the vertical stabiliser leading edge and the fuselage.
If the inspection reveals:
- there is no gap between the vertical stabiliser leading edge and the fuselage, the aircraft is considered airworthy.
b. there is a gap between the vertical stabiliser leading edge and the fuselage, before further flight, contact the manufacturer.
2. Check through the air cooling oval hole, located on the leading edge of the vertical stabiliser, the presence of the vertical stabiliser forward junction doubler.
If the inspection reveals:
- the vertical stabiliser small spar junction doubler is installed, return the aircraft to service.
b. the absence of the vertical stabiliser forward junction doubler, before further flight, contact the manufacturer.
Note 1: Model TB200 aircraft were subject to the requirements of Direct Mail AD/TB 20/34, and are now subject to the requirements of this Directive which is specific to the Model TB200.
Note 2: DGAC AD T1999-319(A) refers.
Compliance: 1. At each pre-flight inspection after 7 October 1999; until Requirement 2 is accomplished.
2. Within 50 hours time in service after 7 October 1999, or at the next periodic inspection after 7 October 1999, whichever occurs first; unless already accomplished.
Note: This Directive shall be entered on the Maintenance release as maintenance required. The visual inspection required by Requirement 1 may be performed by the Pilot in Command, in which case certification is to be made by entering AD/TB200/3 against the daily inspection certification of the Maintenance Release. A copy of this Airworthiness Directive is to be kept in the aircraft.
This Airworthiness Directive becomes effective on 7 October 1999.
Background: The DGAC received a report that indicated the vertical stabiliser forward junction doubler was missing on a Model TB10 aircraft.
COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Overview
The Civil Aviation Regulations 1998, under Part 39 - 105, address the safety and airworthiness of aircraft within Australia through the issuance of airworthiness directives. The 1998 Regulations were enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, ensuring that all civil aircraft meet the highest safety standards. One specific airworthiness directive, AD/TB 200/3, was introduced to address issues identified with the vertical stabiliser forward junction doubler on Aerospatiale (Socata) TB 200 Series Aeroplanes. This directive was implemented following a report from the Direction Générale de l'Aviation Civile (DGAC) indicating that the vertical stabiliser forward junction doubler was missing on a Model TB10 aircraft. The policy objective of this directive is to ensure the continued airworthiness of the affected aircraft by mandating specific inspections and actions by operators and manufacturers.
The Civil Aviation Safety Authority, as the enforcing body under the Civil Aviation Act 1988, issued this directive to mandate the required inspections and actions to rectify identified safety issues. The directive requires operators of all Model TB200 aircraft to perform visual inspections to verify the integrity of the vertical stabiliser and to check for the presence of the vertical stabiliser forward junction doubler. If any deficiencies are found, operators are required to contact the manufacturer before further flight. The directive aims to ensure that any gaps or missing components are addressed promptly to maintain the safety and airworthiness of the aircraft.
Scope and Application
The Civil Aviation Regulations 1998, under the Civil Aviation Safety Authority, apply to all Model TB200 aircraft, mandating specific airworthiness directives concerning the vertical stabiliser and its junction with the fuselage. These regulations require a visual inspection to verify that there is no gap between the vertical stabiliser leading edge and the fuselage, and also mandate the presence of the vertical stabiliser forward junction doubler as viewed through the air cooling oval hole on the leading edge of the vertical stabiliser. If either inspection reveals issues, the aircraft operator must contact the manufacturer before further flight. The directive requires compliance at each pre-flight inspection and within 50 hours of service or at the next periodic inspection after the effective date of 7 October 1999. The pilot in command can perform the visual inspection, with certification noted on the Maintenance Release. This directive applies nationally and is specific to the Model TB200, superseding previous directives such as AD/TB 20/34, and references DGAC AD T1999-319(A) for further information.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39 - 105, contain specific Airworthiness Directives (AD) for the Aerospatiale (Socata) TB 200 Series Aeroplanes, with AD/TB 200/3 addressing the Vertical Stabiliser Forward Junction Doubler. This directive applies to all Model TB200 aircraft (s 1). The main requirements outlined in the directive are to perform a visual inspection to ensure there is no gap between the vertical stabiliser leading edge and the fuselage (s 1a) and to check through the air cooling oval hole on the leading edge of the vertical stabiliser for the presence of the vertical stabiliser forward junction doubler (s 1b). If the inspection reveals no gap or if the doubler is present, the aircraft is considered airworthy. However, if there is a gap or if the doubler is absent, the directive mandates contacting the manufacturer before further flight.
The obligations imposed by this directive are clear. Operators must ensure that the visual inspection of the vertical stabiliser and fuselage junction is conducted at each pre-flight inspection (s 2a). Additionally, within 50 hours of time in service after 7 October 1999, or at the next periodic inspection, whichever comes first, unless already accomplished, the checks must be performed (s 2b). The results of the visual inspection must be documented on the Maintenance Release, and a copy of the Airworthiness Directive must be kept in the aircraft (s 2c). The directive explicitly states that this requirement becomes effective from 7 October 1999.
Failure to comply with the requirements of this Airworthiness Directive can lead to significant consequences. The directive outlines that any non-compliance could potentially result in serious safety issues, as evidenced by the report received by the DGAC indicating the vertical stabiliser forward junction doubler was missing on a Model TB10 aircraft. While specific penalties are not detailed in the text, non-compliance with Civil Aviation Regulations can generally result in enforcement actions, fines, and potential grounding of the aircraft. Such actions are aimed at ensuring the highest safety standards in aviation are met and enforced.
