AD/B767/126 Lower Body Anti-Collision Light and Cable Assembly
10/2000
Applicability: Model 767-200, -300 and -300F series aeroplanes; line numbers 1 through 739 inclusive.
Requirement: 1. Carry out either of the following actions in accordance with Boeing Service Bulletin (SB) 767-33A0075, Revision 1, dated 27 May 1999:
- Perform a one-time general visual inspection to detect damage or chafing of the insulation or wires, and modify the cable assembly of the lower body anti- collision cable assembly.
or,
b. Replace the cable assembly of the lower body anti-collision cable assembly with a new cable assembly.
2. If any damage or chafing is detected during the Requirement 1.a. inspection, repair the damaged or chafed part.
Note 1: SB 767-33A0075, Revision 1, refers to Grimes SB 60-3414-33-SB01, dated 8 December 1998, as an additional source of service information for accomplishment of the modification required by Requirement 1.a. of this Directive. Since Boeing issued the service bulletin, Grimes has issued SB 60-3414-33-SB01, Revision 1, dated 13 March 2000. Revision 1 of the Grimes service bulletin is an additional source of service information for accomplishment of the modification required by Requirement
1.a. of this Directive.
Note 2: For the purposes of this Directive, a general visual inspection is defined as:
"A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or drop-light, and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked."
Note 3: FAA AD 2000-16-14 Amdt 39-11871 refers.
COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Compliance: For Requirement 1 - Within 1800 hours time in service from the effective date of this Directive.
For Requirement 2 - Before further flight.
This Airworthiness Directive becomes effective on 5 October 2000.
Background: The Federal Aviation Administration has received reports of electrical arcing on structure near the lower body anti-collision light due to chafing of the cable. This Directive requires either an inspection to detect damage or chafing of the insulation or wires, modification of the cable assembly, and repairs, if necessary; or replacement of the cable assembly of the lower anti-collision light with a new cable assembly. These actions are intended to prevent chafing as a result of improper installation of the lower body anti-collision light assembly, which could result in electrical arcing or sparking in a flammable leakage zone of the aeroplane.

Delegate of the Civil Aviation Safety Authority 25 August 2000
The above AD is notified in the Commonwealth of Australia Gazette on 6 September 2000.
Overview
The Civil Aviation Regulations 1998, amended by PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITYSCHEDULE OF AIRWORTHINESS DIRECTIVES, was enacted to address safety concerns in civil aviation. This legislation specifically targets the maintenance and inspection of aircraft to prevent potential hazards that could compromise flight safety. The Airworthiness Directive issued under this regulation mandates corrective actions for specific aircraft models to ensure compliance with safety standards. This directive was issued by the Civil Aviation Safety Authority (CASA), whose policy objective is to maintain the highest standards of safety in civil aviation. The directive was designed to address reports of electrical arcing due to cable chafing in Boeing 767 series aeroplanes, aiming to prevent potential electrical arcing or sparking in flammable areas, thereby ensuring the continued airworthiness of these aircraft.
Scope and Application
The Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 applies specifically to Boeing 767-200, -300, and -300F series aeroplanes with line numbers ranging from 1 through 739 inclusive. The directive mandates corrective actions to address a safety concern related to the lower body anti-collision light and its cable assembly. The AD requires either a one-time visual inspection to detect any damage or chafing of the insulation or wires, followed by a modification of the cable assembly, and repairs if necessary, or the replacement of the entire cable assembly with a new one. These actions must be completed within 1800 hours of the AD's effective date or before further flight, depending on the specific requirement. This AD applies to all aircraft within the specified model and line number range, ensuring that the necessary safety measures are implemented to prevent potential electrical arcing or sparking in a flammable leakage zone of the aeroplane. The AD's scope is limited to these particular aircraft models and does not extend to other types of aircraft or aeronautical products.
Key Provisions
The Civil Aviation Regulations 1998, specifically PART 39 - 105, establishes a schedule of Airworthiness Directives (AD) for Boeing 767 series aeroplanes. Section 105 (1) of CAR 1998 empowers the Civil Aviation Safety Authority (CASA) to issue these directives to ensure the airworthiness of aircraft. In this case, AD/B767/126 pertains to the lower body anti-collision light and cable assembly (paragraph 1). The applicability section (paragraph 2) specifies that this AD applies to Model 767-200, -300, and -300F series aeroplanes, covering line numbers 1 through 739 inclusive. The requirement section (paragraph 3) mandates either a one-time general visual inspection and modification of the cable assembly, or replacement of the cable assembly altogether, to prevent damage or chafing of the insulation or wires, which could result in electrical arcing or sparking in a flammable leakage zone of the aeroplane. Repairs are necessary if any damage or chafing is detected during the inspection.
The AD imposes obligations on the parties governed by it, primarily those who operate Boeing 767 series aeroplanes within the specified applicability range. They must comply with the requirements outlined in the directive to ensure the safety of their aircraft. This includes conducting a thorough visual inspection and making necessary modifications or repairs, or replacing the cable assembly as instructed. Failure to comply with these requirements may result in the aircraft being deemed unairworthy, leading to potential grounding and legal consequences. Operators must also adhere to the compliance timeline, ensuring that the actions are completed within 1800 hours time in service from the effective date of the AD, or before further flight, depending on the requirement.
There are no explicit offences, penalties, or civil/criminal consequences stated within the AD itself. However, non-compliance with ADs can lead to regulatory actions, including fines, sanctions, or other enforcement measures imposed by CASA. Additionally, failure to adhere to the AD may result in the aircraft being grounded, leading to operational disruptions and potential financial losses for the operator. The severity of penalties or consequences for non-compliance would depend on the specific circumstances and any applicable laws or regulations.
