AD/CESSNA 188/16 Amdt 1 - Fuselage Lower Longerons

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain a schedule of airworthiness directives intended to ensure the safe operation of civil aircraft. One such directive, AD/CESSNA 188/16 Amendment 1, pertains to the Cessna 188 (Agwagon) series aeroplanes and was enacted to address specific safety concerns identified with the fuselage lower longerons. This regulation was introduced to mitigate the risk of structural failure in these aircraft by requiring regular inspections for cracks in the vicinity of the main landing gear supports, particularly for models A188 excluding certain configurations. The policy objective is to maintain and enhance the safety of civil aviation operations by ensuring that aircraft are maintained to the highest safety standards. This amendment was made under the authority of the Civil Aviation Regulations 1998 by the Civil Aviation Safety Authority, reflecting a commitment to the ongoing safety and airworthiness of civil aircraft in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives and applies to all Cessna 188 (Agwagon) Series Aeroplanes with particular attention to their airworthiness. This legislative instrument mandates inspections of the fuselage lower longerons for cracks in the vicinity of the main landing gear supports, and it applies to all models of the A188 series except those with an aircraft serial number ending in a “T” suffix, as well as those that have undergone modifications approved by the Secretary. The geographical scope of this regulation is national, as it is issued under the authority of the Commonwealth of Australia and applies to all aircraft operating within Australian jurisdiction. Compliance with these airworthiness directives is mandatory and must be adhered to within specified time frames, starting within 100 hours of time in service for aeroplanes with more than 1500 hours of total time in service and subsequently at intervals not exceeding 500 hours of time in service following 1 September 1971. These regulations do not apply to aircraft that have already been modified in accordance with an approved scheme, thus providing an exemption for those specific cases. The application of these regulations may be further detailed or extended through subordinate instruments, ensuring that the safety standards are effectively implemented and maintained across the industry.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, includes AD/CESSNA 188/16 Amendment 1 which pertains to the Cessna 188 (Agwagon) Series Aeroplanes. This legislation is focused on the inspection requirements of the fuselage lower longerons to ensure safety and airworthiness. Section 1 of this directive states the applicability of the inspection mandate, which applies to all models of the A188 series, excluding those with an aircraft serial number ending in "T" and those that have undergone modifications approved by the Secretary (section 1). The requirement for inspection is outlined in section 11/86, which mandates that the fuselage lower longerons must be inspected for cracks, particularly in the vicinity of the main landing gear supports. This airworthiness directive imposes specific obligations on the owners or operators of the Cessna 188 (Agwagon) aeroplanes. According to the directive, inspections must be conducted within 100 hours of time in service for all aeroplanes that have accumulated more than 1500 hours of total time in service, and this inspection must occur after 1 September 1971. Further, the inspections must be repeated at intervals not exceeding 500 hours of time in service (section 11/86). Compliance with these inspection intervals is critical to maintaining the airworthiness of the aircraft and ensuring passenger and crew safety. Failure to comply with the inspection requirements outlined in the Civil Aviation Regulations 1998 can result in serious consequences. Although the specific civil or criminal penalties are not detailed within the excerpted text, it is reasonable to infer that non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority. Such actions could include fines, suspension or revocation of airworthiness certificates, and potentially, criminal charges if the non-compliance results in safety incidents or accidents. The penalties for these breaches are likely to be severe, given the importance of adhering to airworthiness standards in aviation.
