Fokker F28 Series Aeroplanes
AD/F28/88 Cargo Restraint Strap Assemblies 1/2005
DM
Applicability: Model F28 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.
Fokker F28 Series Aeroplanes
AD/F28/88 (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) introduced the Airworthiness Directive (AD) F28/88 on 1 December 2004, specifically addressing safety concerns related to the installation and use of cargo restraint strap assemblies on Fokker F28 series aircraft. This AD was enacted to mitigate the risk of shifting or unrestrained cargo, which could lead to an unexpected change in the aircraft’s centre of gravity, potential damage to the aircraft structure or flight control system, and hazards to the flight crew, possibly resulting in a loss of control. The AD requires modifications to the Aircraft Flight Manual and the Weight and Balance Manual to include specific instructions on the use of certain cargo restraint straps, ensuring compliance with the directive within 14 days of its effective date. The policy objective of this AD is to enhance the safety of air travel by ensuring that cargo is adequately secured, thus preventing potential in-flight hazards and ensuring the structural integrity of the aircraft.
Scope and Application
The Airworthiness Directive (AD) issued under the Civil Aviation Safety Regulations 1998 applies specifically to Fokker F28 series aircraft that have had cargo restraint strap assemblies part number 1519-MCIDS installed in accordance with Supplemental Type Certificate (STC) ST01004NY. The directive is issued by the delegate of the Civil Aviation Safety Authority (CASA) and is intended to address safety concerns related to cargo shifting or being unrestrained, which could lead to hazardous conditions such as unexpected changes in the aircraft’s centre of gravity, structural damage, compromised flight control, and potential loss of control. The directive mandates that the applicable aircraft's Aircraft Flight Manual (AFM) and Weight and Balance Manual (WBM) must be revised to incorporate specific instructions regarding the use of the aforementioned cargo restraint straps, effectively discontinuing the use of STC ST01004NY for installing these straps as the sole means of securing cargo. The compliance timeframe requires these changes to be made within 14 days of 1 December 2004, the date from which the directive becomes effective. This AD is a Commonwealth regulation, binding within Australia’s national jurisdiction.
Key Provisions
The Airworthiness Directive (AD) issued under subregulation 39.1(1) of the Civil Aviation Safety Regulations 1998 (CASR 1998) applies to Fokker F28 Series Aeroplanes that have cargo restraint strap assemblies part number 1519-MCIDS installed via Supplemental Type Certificate (STC) ST01004NY (Section 1). The primary requirement outlined in this AD is to revise the Limitations Section of the Aircraft Flight Manual (AFM) and the cargo-loading procedures in the Weight and Balance Manual (WBM) to include specific information regarding the use of these cargo restraint straps. Specifically, the AFM and WBM must reflect the directive's instruction to discontinue using STC ST01004NY for installing these straps as the sole means of securing cargo to Technical Standard Order (TSO) C90c/NAS3610 pallets (Section 1).
This AD imposes clear obligations on the operators of Fokker F28 Series Aeroplanes. They must ensure that the AFM and WBM are updated to incorporate the specified changes within 14 days of 1 December 2004 (Section 3). The AD mandates that the revised manuals explicitly state that the cargo restraint straps in question can only be used as supplemental restraints for securing cargo to TSO C90c/NAS3610 pallets or to the cargo restraint fittings in the aircraft floor, as long as this is within the strap's rated load of 5,000 lbs (Section 1). If the updates are incorporated into general revisions of the AFM and WBM, the AD may be removed from these manuals (Note 1, Section 1).
Failure to comply with this Airworthiness Directive could result in severe consequences, as the directive aims to prevent potential hazards such as shifting or unrestrained cargo. Such hazards could lead to an unexpected change in the aircraft’s centre of gravity, resulting in damage to the aircraft structure and/or flight control system, posing a hazard to the flight crew, and potentially causing loss of controllability of the aircraft (Section 1). The AD becomes effective on 1 December 2004, and non-compliance could be subject to penalties under the Civil Aviation Act 1988 and associated regulations, although specific penalties are not detailed in this AD. The overarching goal of the directive is to maintain the airworthiness and safety standards of Fokker F28 Series Aeroplanes in accordance with Australian aviation safety regulations.
