AD/B747/318 Cargo Restraint Strap Assemblies 1/2005
DM
Applicability: Model 747 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.

AD/B747/318 (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.

Delegate of the Civil Aviation Safety Authority 24 November 2004
The above AD is notified in the Commonwealth of Australia Gazette on 1 December 2004.
Overview
The Civil Aviation Safety Authority (CASA) issued Airworthiness Directive AD/B747/318 on 24 November 2004 to address a safety issue related to the Boeing 747 series aircraft. This legislation was enacted to ensure the safe operation of aircraft by addressing potential hazards from improperly secured cargo, which could lead to unforeseen shifts in the aircraft's centre of gravity, structural damage, flight control issues, and risks to flight crew safety. The directive applies to Model 747 series aircraft equipped with cargo restraint strap assemblies part number 1519-MCIDS installed under Supplemental Type Certificate ST01004NY. The requirement outlined in the directive mandates the revision of the Aircraft Flight Manual and the cargo-loading procedures in the Weight and Balance Manual to include specific instructions for discontinuing the use of certain cargo restraint straps as the sole means of securing cargo. This measure aims to mitigate the risks associated with unsecured or improperly secured cargo, thereby enhancing overall aviation safety.
Scope and Application
The Airworthiness Directive AD/B747/318 issued by the Civil Aviation Safety Authority (CASA) applies to Model 747 series aircraft that have installed cargo restraint strap assemblies part number 1519-MCIDS under the Supplemental Type Certificate (STC) ST01004NY. The directive mandates that specific revisions be made to the Aircraft Flight Manual (AFM) and the Weight and Balance Manual (WBM) to address safety concerns related to cargo restraint. These revisions include discontinuing the use of the STC ST01004NY for installing certain cargo restraint straps as the sole means of securing cargo, though they can still be used as supplemental restraints within specified limits. The directive is applicable nationwide across Australia, reflecting CASA's regulatory authority under the Civil Aviation Safety Regulations 1998. The directive excludes any aircraft not fitting the specified criteria and must be complied with within 14 days from 1 December 2004. The AD extends its application through the incorporation of its provisions into the AFM and WBM, superseding any previous directives on the matter.
Key Provisions
The Airworthiness Directive (AD) B747/318 issued under the Civil Aviation Safety Regulations (CASR) 1998 pertains specifically to Boeing 747 series aircraft that have installed cargo restraint strap assemblies part number 1519-MCIDS via Supplemental Type Certificate (STC) ST01004NY (section 1). This AD mandates that certain changes be made to the Aircraft Flight Manual (AFM) and the Weight and Balance Manual (WBM) to ensure safer cargo restraint practices (section 1). The requirement section stipulates that the AFM and WBM must be updated to include a specific statement that discontinues the use of STC ST01004NY for installing these cargo restraint straps as the primary method for securing cargo to TSO C90c/NAS3610 pallets, while permitting their continued use as supplemental restraints under certain conditions (section 1).
The AD imposes specific obligations on the operators of Boeing 747 series aircraft that fall under its applicability. Operators must revise their AFM and WBM within 14 days after 1 December 2004, by including the directive's specified statement. This requirement may be fulfilled by incorporating the directive into the manuals or by inserting a copy of the directive itself into the manuals, with the possibility of removing the copy once the general revisions are incorporated (section 1). The AD also references FAA AD 2004-22-01 Amdt 39-13829, indicating alignment or correlation with the Federal Aviation Administration's similar directives (section 1).
Failure to comply with the requirements of this AD may result in unsafe conditions that could lead to various hazards, including unexpected changes in the aircraft's centre of gravity, damage to the aircraft's structure and flight control systems, hazards to the flight crew, and potential loss of controllability of the aircraft (section 1). While the AD does not explicitly state civil or criminal penalties for non-compliance, the overarching Civil Aviation Safety Regulations 1998 provide a framework within which non-compliance could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include fines, enforcement notices, and other regulatory measures aimed at ensuring compliance with aviation safety standards.
