Boeing 767 Series Aeroplanes
AD/B767/202 Cargo Restraint Strap Assemblies 1/2005
DM
Applicability: Model 767 series aircraft, on which cargo restraint strap assemblies part number 1519-MCIDS have been installed per Supplemental Type Certificate (STC) ST01004NY.
Requirement: Revise the Limitations Section of the Aircraft Flight Manual (AFM), and the cargo- loading procedures of the Weight and Balance Manual (WBM), to include the following information (this may be accomplished by inserting a copy of this Directive into the AFM and the WBM):
“Discontinue the use of STC ST01004NY to install Airline Container Manufacturing Company Inc., cargo restraint straps, part number 1519-MCIDS, as the only means of securing cargo to Technical Standard Order (TSO) C90c/NAS3610 pallets. Such cargo restraint straps may continue to be used a supplemental restraints to secure cargo to TSO C90c/NAS3610 pallets, or to the cargo restraint fittings in the aircraft floor, per the aircraft manufacturer’s weight and balance manuals, and within the strap rated load (5,000 lbs).”
Note 1: If the above statement has been incorporated into the general revisions of the AFM and the WBM, the general revisions may be incorporated into the AFM and WBM, and the copy of this Directive may then be removed from the AFM and WBM.
Note 2: FAA AD 2004-22-01 Amdt 39-13829 refers.
Compliance: Within 14 days after 1 December 2004.
This Airworthiness Directive becomes effective on 1 December 2004.
Boeing 767 Series Aeroplanes
AD/B767/202 (continued)
Background: The actions specified by this Directive are intended to prevent shifting or unrestrained cargo in the cargo compartment, which could cause an unexpected change in the aircraft’s centre of gravity, damage to the aircraft structure and/or flight control system, a hazard to the flightcrew, and/or possible loss of controllability of the aircraft.

The above AD is notified in the Commonwealth of Australia Gazette on 1 December 2004.
Overview
The Airworthiness Directive (AD) B767/202 issued under the Civil Aviation Safety Regulations 1998 (CASR 1998) addresses safety concerns related to the installation and use of certain cargo restraint strap assemblies in Boeing 767 series aeroplanes. Enacted in 2004, this directive was introduced to ensure the safe operation of these aircraft by preventing issues such as shifting or unrestrained cargo that could compromise the aircraft’s stability and control. The directive was issued by the Civil Aviation Safety Authority (CASA) to mandate specific changes to the Aircraft Flight Manual (AFM) and the Weight and Balance Manual (WBM) to prevent unsafe conditions that could arise from the improper use of the cargo restraint straps. The policy objective is to maintain the highest safety standards in the operation of Boeing 767 series aeroplanes by ensuring that cargo is securely restrained in a manner that prevents any adverse impact on the aircraft's performance and safety.
Scope and Application
The Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Safety Regulations (CASR) 1998 pertains specifically to Boeing 767 series aeroplanes equipped with cargo restraint strap assemblies part number 1519-MCIDS installed per Supplemental Type Certificate (STC) ST01004NY. This directive applies to aircraft within the Commonwealth of Australia, ensuring compliance with safety standards to prevent issues such as cargo shifting, which could adversely affect the aircraft's stability and control. The requirement mandates that operators revise the Aircraft Flight Manual (AFM) and the Weight and Balance Manual (WBM) to prohibit the use of STC ST01004NY for installing certain cargo restraint straps as the sole means of securing cargo. Instead, these straps can only be used as supplementary restraints within specified load limits. The compliance period for these revisions is set within 14 days from 1 December 2004, and the directive became effective on the same date it was issued.
Key Provisions
This Airworthiness Directive (AD) applies to Boeing 767 series aircraft that have installed cargo restraint strap assemblies part number 1519-MCIDS, in accordance with the Supplemental Type Certificate (STC) ST01004NY (AD/B767/202, Applicability). The directive requires the revision of the Aircraft Flight Manual (AFM) and the cargo-loading procedures of the Weight and Balance Manual (WBM) to include specific information about the use of these cargo restraint straps (AD/B767/202, Requirement). This information specifies that STC ST01004NY should no longer be used to install the cargo restraint straps as the sole means of securing cargo to TSO C90c/NAS3610 pallets. Instead, these straps can only be used as supplemental restraints, in accordance with the aircraft manufacturer’s weight and balance manuals and within the straps’ rated load of 5,000 lbs (AD/B767/202, Requirement).
The AD imposes specific obligations on the operators of the affected Boeing 767 series aircraft. Operators must ensure that the AFM and WBM are updated to include the revised cargo-loading procedures and limitations, as specified in the AD. This involves either inserting a copy of the AD into the AFM and WBM, or incorporating the AD's instructions into the general revisions of these manuals. If the latter option is chosen, the copy of the AD can be removed from the AFM and WBM once the general revisions are incorporated (AD/B767/202, Requirement, Note 1). Moreover, operators must ensure that these revisions are completed within 14 days of 1 December 2004 (AD/B767/202, Compliance).
Failure to comply with the AD can result in severe consequences. The AD is intended to mitigate the risk of shifting or unrestrained cargo in the cargo compartment, which could lead to an unexpected change in the aircraft’s centre of gravity, damage to the aircraft structure and/or flight control system, a hazard to the flight crew, and/or loss of controllability of the aircraft (AD/B767/202, Background). Although the specific penalties for non-compliance are not stated in the AD, non-compliance with airworthiness directives is generally taken seriously by regulatory authorities and could result in enforcement actions, fines, or other legal consequences. Ensuring adherence to the AD is therefore crucial for maintaining the safety and airworthiness of the affected aircraft.
