COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 737 Series Aeroplanes
AD/B737/114
Amdt 1
Aileron 6/98
Applicability: All Model 737-100, -200, -300, -400, and -500 series aircraft.
Requirement: a. Perform a one-time visual inspection to determine if an aileron built by Tramco Inc. (trading as BFGoodrich Aerospace, Repair Station HN6R593N), having any of the following serial numbers and correlating part numbers is installed on the aircraft:
Serial Number | Part Number |
BN23 | 65-46454-22 |
BN49 | 65-46454-23 |
BN56 | 65-46454-24 |
BN59 | 65-46454-24A |
BN167 | 65-46454-24 |
BN180 | 65-46454-23 |
BN206 | 65-46454-2 |
BN236 | 65-46454-24 |
162 | 65-46454-24 |
237 | 65-46454-24 |
b. If any aileron is found with an affected serial number and correlating part number identified in Requirement paragraph (a), remove the defective aileron, and replace it with a new or serviceable aileron.
Note: FAA AD 98-03-09 Amdt 39-10301 refers.
Compliance: Unless already accomplished, before 21 July 1998.
This amendment becomes effective on 21 May 1998.
Background: The FAA received two reports of failure of the aileron on Boeing Model 737 series aircraft. In one incident, a two-foot section of an aileron separated from the aircraft during descent, which resulted in vibration of the flight controls. In the second incident, 30 percent of an aileron separated from the aircraft during climb.
Investigation revealed that the cause of these failures has been attributed to an inappropriate repair procedure.
Amendment 1 is issued in response to a new FAA AD which gives additional information that specifies the identification of certain part numbers.
The original issue of this Airworthiness Directive became effective on 26 February 1998.
Overview
The Civil Aviation Regulations 1998, as amended by the Boeing 737 Series Aeroplanes AD/B737/114 Amendment 1, was enacted to address safety concerns related to aileron failures in Boeing 737 series aircraft. This legislation was introduced by the Civil Aviation Safety Authority in response to reports of aileron failures on Boeing 737 aircraft, which were attributed to inappropriate repair procedures. The policy objective of this amendment is to ensure the continued airworthiness of affected aircraft by requiring a visual inspection of specific ailerons and their replacement if necessary, to prevent further incidents of aileron failure. This legislative instrument aims to enhance aviation safety by mandating the removal and replacement of defective ailerons on specified Boeing 737 models.
Scope and Application
The Civil Aviation Regulations 1998, as amended, apply to all Model 737-100, -200, -300, -400, and -500 series aircraft within the Commonwealth of Australia. These regulations mandate specific actions to ensure airworthiness and safety of the aircraft, particularly regarding components such as the aileron. This particular directive, AD/B737/114, requires operators of affected Boeing 737 series aeroplanes to perform a one-time visual inspection to identify if a specific aileron manufactured by Tramco Inc. (trading as BFGoodrich Aerospace) with certain serial and part numbers is installed on their aircraft. If any defective aileron is found, it must be removed and replaced with a new or serviceable one. Compliance with this directive is mandatory and must be achieved before 21 July 1998. This amendment is part of the broader regulatory framework aimed at maintaining high safety standards in the aviation industry and is closely aligned with the Federal Aviation Administration's (FAA) directives.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the requirements and compliance measures for Boeing 737 series aeroplanes. Under this regulation, Airworthiness Directive AD/B737/114 Amendment 1 pertains to the inspection and replacement of ailerons built by Tramco Inc. (trading as BFGoodrich Aerospace). According to section (a) of the directive, operators must perform a one-time visual inspection to determine if any aileron with certain serial numbers and correlating part numbers is installed on their aircraft. If an affected aileron is found, it must be removed and replaced with a new or serviceable aileron as stated in section (b). This inspection must be completed by 21 July 1998, as stipulated in the compliance section of the directive.
The obligations imposed by this Act require all operators of the specified Boeing 737 models to conduct the specified inspection and replacement procedures to ensure the airworthiness of their aircraft. Operators must ensure that the inspection is carried out thoroughly and that any defective ailerons are replaced without delay. This requirement is critical to maintain the safety standards mandated by the Civil Aviation Safety Authority (CASA).
Failure to comply with the Airworthiness Directive may result in significant legal and safety consequences. Section (b) of the directive clearly states that non-compliance could lead to the continued operation of aircraft with potentially unsafe components, which could result in serious flight control issues. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil penalties, including fines and possible grounding of the aircraft. Additionally, criminal penalties may apply in cases where non-compliance results in serious safety breaches, with maximum penalties including substantial fines and imprisonment. It is essential that operators adhere strictly to these directives to avoid these severe consequences.
