AD/CESSNA 340/19 - Upper Inner Cabin Door Handle and Locking Mechanism - Inspection

Overview

The Civil Aviation Regulations 1998, specifically under PART 39, encompass a comprehensive framework to ensure the safety and airworthiness of aircraft in Australia. One such regulation is AD/CESSNA 340/19, which targets the upper inner cabin door handle and locking mechanism for Cessna 340 Series aeroplanes. This directive was enacted to address the specific safety concerns associated with the aforementioned aircraft models, particularly those with serial numbers ranging from 340A0401 to 340A0499. The Civil Aviation Safety Authority, operating under the authority of the Australian Government, established this directive to mandate regular inspections and maintenance of the specified components, aiming to mitigate risks that could potentially compromise the safety of passengers and crew. The overarching policy objective is to uphold stringent safety standards in civil aviation, ensuring the reliability and security of air travel within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the maintenance and inspection requirements for aircraft within Australia. This particular legislation, AD/CESSNA 340/19, pertains to the inspection of the upper inner cabin door handle and locking mechanism for Cessna 340 series aeroplanes, more precisely model 340A with serial numbers ranging from 340A0401 to 340A0499. The directive requires compliance within 100 hours of time in service after 30 September 1978, as detailed in the document Cessna Service Letter No. ME78-21. This regulation applies exclusively to the specified model and serial number range of the Cessna 340A aircraft, ensuring the safety and airworthiness of these specific aircraft within Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, mandates specific safety directives for aircrafts, particularly the Cessna 340 Series Aeroplanes. Section (AD/CESSNA 340/19) addresses the inspection requirements for the upper inner cabin door handle and locking mechanism. This directive applies to all model 340A with serial numbers ranging from 340A0401 to 340A0499. Compliance must be achieved within 100 hours of time in service following 30 September 1978, as detailed in the Cessna Service Letter No. ME78-21. This legislative instrument imposes several obligations on the relevant parties. Owners or operators of the affected Cessna 340A aircraft must ensure that the upper inner cabin door handle and locking mechanism are inspected and maintained according to the specified schedule. This requirement is critical for ensuring the continued airworthiness and safety of the aircraft. The inspection must be performed by a certified mechanic or technician who is authorised to conduct such maintenance on these specific aircraft models. Failure to comply with the airworthiness directive set forth in this regulation can lead to severe consequences. Non-compliance may result in the aircraft being deemed unairworthy, which could prevent it from being operated legally. In more severe cases, enforcement actions by the Civil Aviation Safety Authority (CASA) could include the imposition of fines or other penalties. The exact penalties are not explicitly detailed in the provided text, but they can include substantial financial penalties or other administrative actions as deemed appropriate by CASA. It is important for all parties involved to adhere strictly to these regulations to avoid any legal repercussions or safety hazards.
