Overview
The Civil Aviation Regulations 1998 (Cth), specifically PART 39 - 105, includes a legislative instrument (F2006B08219) that was enacted to address safety concerns related to the Cessna 336 Series Aeroplanes. The problem this legislation aimed to resolve was the risk of structural failure in the wing front carry-thru spar of certain Cessna 336 aircraft models. This was achieved through the issuance of Airworthiness Directive AD/CESSNA 336/10, which mandates specific inspections and modifications to ensure the continued airworthiness of these aircraft. The directive applies to all Cessna 336 models with serial numbers between 336-0001 and 336-0195, unless they have already been modified according to Service Kit SK 336-19A. The objective of this directive, as outlined in the Civil Aviation Regulations, is to ensure that the aircraft meet safety standards, thereby enhancing overall aviation safety. This legislative instrument was enacted by the Parliament of Australia, reflecting the commitment to maintaining stringent safety regulations in the aviation industry.
Scope and Application
The Civil Aviation Safety Authority (CASA) regulations, specifically the AD/CESSNA 336/10 Airworthiness Directive pertaining to the Cessna 336 Series Aeroplanes, outline critical requirements for the inspection and modification of the wing front carry-thru spar. This directive applies to all Cessna 336 models with serial numbers ranging from 336-0001 to 336-0195 that have not undergone modifications in accordance with Service Kit SK 336-19A. The directive is issued under the Civil Aviation Regulations 1998, enforcing stringent safety standards to ensure the airworthiness of these aircraft. The regulations are binding nationwide, impacting both commercial and private aviation sectors operating within Australia. The directive mandates specific inspection and modification intervals, with aircraft accumulating more than 2975 hours of total time in service by 14 May 1974 needing inspection within 25 hours after that date and subsequently at intervals not exceeding 100 hours. For other aircraft, inspections must occur before reaching 3000 hours of total time in service, with subsequent inspections not exceeding 100 hours of service. The scope of these regulations is comprehensive, covering all relevant entities and operations within the Australian jurisdiction, with no exclusions explicitly stated in the provided text.
Key Provisions
The Civil Aviation Regulations 1998, specifically within Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, address the maintenance and safety requirements for the Cessna 336 Series Aeroplanes. The directive AD/CESSNA 336/10 pertains to the inspection and modification of the wing front carry-thru spar (section 5/74). This directive applies to all Cessna 336 models with serial numbers ranging from 336-0001 to 336-0195 that have not been modified in accordance with Service Kit SK 336-19A. The document referenced for compliance is Cessna SL ME74-4.
For aircraft that have accrued more than 2975 hours of total time in service as of 14 May 1974, the inspection and modification must occur within 25 hours of time in service following 14 May 1974. Subsequent inspections and modifications are mandated at intervals not exceeding 100 hours of time in service. For all other affected aircraft, the initial inspection and modification must take place before the aircraft exceeds 3000 hours of total time in service, with follow-up inspections and modifications required at intervals not exceeding 100 hours of time in service.
The Act imposes specific obligations on the owners and operators of the Cessna 336 Series Aeroplanes to ensure compliance with these airworthiness directives. Owners and operators must ensure that the wing front carry-thru spar is inspected and modified according to the specified timelines and intervals. This involves meticulous record-keeping of the aircraft's total time in service and scheduling inspections and modifications at the prescribed intervals. Failure to adhere to these requirements can result in non-compliance with the Civil Aviation Regulations 1998, potentially leading to the aircraft being deemed unairworthy.
Breach of these airworthiness directives can lead to significant legal consequences. The Act provides for both civil and criminal penalties for non-compliance. Civil penalties may include fines, while criminal penalties can result in imprisonment, reflecting the seriousness of ensuring the safety and airworthiness of aircraft. The specific maximum penalties are not detailed within the directive itself but are governed by broader provisions within the Civil Aviation Regulations 1998, which may include substantial fines and terms of imprisonment depending on the severity and intent of the breach.
