Fokker F100 (F28 Mk 100) Series Aeroplanes
AD/F100/62 Cargo Restraint Strap Assemblies 1/2005
DM
Applicability: Model F28 Mk. 0100 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 F100 (F28 Mk 100) Series Aeroplanes
AD/F100/62 (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 Airworthiness Directive F28/100/62 in 2004 to address an identified safety issue with the Fokker F100 (F28 Mk 100) series aeroplanes, specifically those equipped with cargo restraint strap assemblies part number 1519-MCIDS installed under Supplemental Type Certificate (STC) ST01004NY. The directive was issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998 and is intended to mitigate the risk of cargo shifting or becoming unrestrained during flight, which could lead to significant safety hazards including damage to the aircraft structure, compromised flight control systems, and potential loss of control. The directive mandates the revision of the Aircraft Flight Manual and the cargo-loading procedures of the Weight and Balance Manual to explicitly prohibit the sole use of the specified cargo restraint straps for securing cargo to TSO C90c/NAS3610 pallets, while still allowing their use as supplemental restraints within the specified load limits. This change is to be implemented within 14 days of the directive's effective date of 1 December 2004, aiming to enhance the overall safety and airworthiness of the affected aircraft.
Scope and Application
The Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) applies specifically to Fokker F100 (F28 Mk 100) series aeroplanes that have cargo restraint strap assemblies part number 1519-MCIDS installed according to the Supplemental Type Certificate (STC) ST01004NY. This directive mandates that operators revise their Aircraft Flight Manual (AFM) and Weight and Balance Manual (WBM) to incorporate specific information regarding the use of these cargo restraint straps, ensuring they are only used as supplemental restraints within the stipulated load limits. This requirement aims to prevent unsafe conditions such as cargo shifting or becoming unrestrained, which could lead to significant operational hazards. The directive applies across the Commonwealth of Australia and is effective from 1 December 2004, with compliance required within 14 days of this date. The AD does not extend to other aircraft models or configurations not specifically mentioned and is limited to the conditions and requirements detailed within the directive itself.
Key Provisions
The main operative sections of the Airworthiness Directive (AD/F100/62) focus on specific requirements for the Fokker F100 (F28 Mk 100) series aircraft that have had the cargo restraint strap assemblies installed per Supplemental Type Certificate (STC) ST01004NY. The requirement section stipulates that the Limitations Section of the Aircraft Flight Manual (AFM) and the cargo-loading procedures of the Weight and Balance Manual (WBM) must be revised. This revision involves inserting specific information to discontinue the exclusive use of STC ST01004NY for installing Airline Container Manufacturing Company Inc. cargo restraint straps, part number 1519-MCIDS, as the sole means of securing cargo to Technical Standard Order (TSO) C90c/NAS3610 pallets. However, these straps can still be used as supplemental restraints, provided they are within their rated load of 5,000 lbs, in accordance with the aircraft manufacturer’s weight and balance manuals. This directive becomes effective on 1 December 2004, and the compliance must be achieved within 14 days of this date.
The AD imposes several obligations and requirements on the parties involved. Operators and owners of Fokker F100 (F28 Mk 100) series aircraft with the specified cargo restraint strap assemblies must revise their AFM and WBM as per the directive’s instructions. This includes inserting the specified text into the manuals and ensuring that the cargo-loading procedures are updated accordingly. The directive is clear that the cargo restraint straps can still be used under certain conditions but must be managed according to the outlined specifications. The directive also references the FAA AD 2004-22-01 Amdt 39-13829, indicating a coordinated effort with international aviation authorities to address the safety issue.
Failure to comply with the AD may result in serious safety risks, including shifting or unrestrained cargo that could lead to an unexpected change in the aircraft’s centre of gravity, potential damage to the aircraft structure and flight control system, and hazards to the flight crew. Such non-compliance could also result in the possible loss of controllability of the aircraft. Although the specific penalties for breach are not detailed in the AD, non-compliance with airworthiness directives is generally considered a serious matter and can result in enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include fines, operational restrictions, or even grounding of the aircraft until compliance is achieved.
