COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Fokker F100 (F28 Mk 100) Series Aeroplanes
AD/F100/14 Small Cargo Door Hinge Assembly 4/99
Applicability: F.28 Mk.0100, serial numbers 11244 through 11408, if equipped with small cargo door hinges Part Number (P/N) A28410-405 or A28410-407.
Requirement: 1. Inspect the fuselage mounted half of P/N A28410-405 or A28410-407 cargo door hinge assemblies in accordance with Section 2, Accomplishment Instructions of Fokker Service Bulletin (SB) F100-52-055 dated 20 July 1994.
2. Replace P/N A28410-405 and -407 with a new hinge assembly P/N D28410-409, in accordance with Fokker SB F100-52-043. Report all findings to the manufacturer.
Note: RLD BLA 93-036/2(A) refers.
Compliance: 1. Inspect in accordance with Requirement 1 at intervals not exceeding 6 starting from the date of issue of this Directive.
2. Replace before further flight, if cracks are found during any inspection, except as provided in section 2. Accomplishment Instructions, Part C, NOTE of Fokker SB F100-52-055.
This Airworthiness Directive becomes effective on 22 April 1999.
Background: Service experience of early F.28 series aircraft has shown that the cargo door hinges are sensitive to stress corrosion cracking. The first issue of the BLA required a one- time inspection of the affected cargo door hinges.
Overview
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, include a schedule of Airworthiness Directives (ADs) to ensure the safety and airworthiness of aircraft in Australian airspace. One such directive is AD/F100/14, which pertains to Fokker F100 (F28 Mk 100) Series Aeroplanes. Enacted in 1998 by the Australian Parliament, these regulations aim to address safety gaps and ensure compliance with civil aviation standards. The AD/F100/14 was introduced to tackle the issue of stress corrosion cracking in the small cargo door hinges of specific Fokker F100 series aircraft, ensuring that any identified faults are rectified to maintain airworthiness and passenger safety. Compliance with these directives is mandatory, with inspections and replacements to be carried out as specified to prevent potential safety hazards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates airworthiness directives that apply to specific aircraft models and their components, with the present focus being on Fokker F100 (F28 Mk 100) series aeroplanes. This legislation is applicable to Fokker F28 Mk.0100 aircraft, serial numbers ranging from 11244 to 11408, that are equipped with specific small cargo door hinges, namely Part Number (P/N) A28410-405 or A28410-407. The directive requires that these aircraft undergo inspection and potential replacement of the cargo door hinges to ensure continued compliance with airworthiness standards. The scope of this directive extends to the entire Commonwealth of Australia, ensuring uniform safety standards across the nation. Exemptions or exclusions from this directive are not explicitly stated in the text, implying that all specified aircraft must adhere to the requirements outlined. This legislation may be extended or restricted through subordinate instruments, though such details are not provided within the text itself.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, include a directive regarding the airworthiness of Fokker F100 (F28 Mk 100) Series aeroplanes, particularly the small cargo door hinge assemblies (AD/F100/14, 4/99). This directive applies to Fokker F28 Mk.0100 aircraft with serial numbers ranging from 11244 to 11408 that are equipped with small cargo door hinges identified by Part Numbers A28410-405 or A28410-407. The directive mandates two primary actions: first, an inspection of the fuselage-mounted half of these cargo door hinge assemblies in accordance with Section 2 of Fokker Service Bulletin (SB) F100-52-055 dated 20 July 1994. Second, these hinges must be replaced with a new hinge assembly identified by Part Number D28410-409, as detailed in Fokker SB F100-52-043, with all findings reported to the manufacturer.
The obligations imposed by this directive include the requirement for inspections to occur at intervals not exceeding six, beginning from the date of issue of this directive. If any cracks are discovered during these inspections, the affected hinges must be replaced before the aircraft can fly again, except in the specific circumstances outlined in Section 2, Part C, NOTE of Fokker SB F100-52-055. Failure to adhere to these requirements can result in the aircraft being deemed non-airworthy, potentially leading to grounding until compliance is achieved.
The directive also specifies the consequences for non-compliance, although it does not explicitly state the penalties. However, non-compliance with Civil Aviation Regulations can lead to serious civil or criminal penalties. The severity of these penalties depends on the nature and extent of the non-compliance, with potential outcomes including fines and, in some cases, imprisonment. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and violations can result in enforcement actions against the aircraft operator or other responsible parties.
In summary, the AD/F100/14 directive is crucial for ensuring the safety of Fokker F100 series aeroplanes by addressing specific issues with cargo door hinge assemblies. Compliance with this directive is mandatory, and failure to adhere to its requirements can have significant legal and safety implications.
