AD/BEECH 400/13 - Spoiler Control Push Rod

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive framework designed to ensure the safety and efficiency of civil aviation within the country. One particular legislative instrument, F2006B03915, addresses the specific issue of maintaining the airworthiness of Beechcraft 400 Series Aeroplanes, particularly focusing on the spoiler control push rods. This regulation was introduced to mitigate the risk of loss of control due to mechanical failures, as evidenced by a reported incident of a missing rivet leading to a loss of roll control shortly after take-off. The policy objective is to ensure that all applicable aircraft undergo a detailed inspection and necessary maintenance to prevent such incidents, thereby enhancing overall aviation safety. Compliance with these directives is mandatory and must be achieved within a specified timeframe following the regulation's enactment.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 applies specifically to Beechcraft 400 Series aeroplanes, more precisely, the Model 400A aircraft with serial numbers RK-1 through RK-96. This directive mandates that a detailed visual inspection be conducted to verify the installation of the securing rivet on the control push rods of the spoiler flight control system and to ensure the jam nut is secure on the opposite rod end, following the guidelines in Beechcraft Safety Communique 400A-113. This requirement is in response to a reported loss of roll control due to a missing rivet, as documented in FAA AD 95-25-05 Amdt 39-9450, and must be completed within 50 hours of time in service after 29 February 1996. The application of this directive is jurisdictional, as it falls under the Commonwealth of Australia's regulation of civil aviation safety, with no stated exclusions or exemptions noted in the provided text. The directive's scope is confined to the specified model and serial numbers of aircraft, indicating a targeted approach to addressing the identified safety issue.

Key Provisions

The key provision of the Civil Aviation Regulations 1998, specifically within Part 39 - 105 and the Schedule of Airworthiness Directives, requires a detailed visual inspection of the spoiler control push rods on Beechcraft 400A aircraft with serial numbers RK-1 through RK-96 (Section 39-105). This inspection must verify the installation of the securing rivet on the control push rods of the spoiler flight control system and ensure that the jam nut is secure on the opposite rod end (Section 39-105). This directive is aligned with Beechcraft Safety Communique 400A-113 and references FAA AD 95-25-05 Amdt 39-9450 (Section 39-105). The obligations imposed by this legislation include conducting the aforementioned inspections within 50 hours of time in service after 29 February 1996. This requirement is crucial to maintain the airworthiness of the aircraft by ensuring that the structural integrity of the spoiler control push rods is not compromised, thereby preventing potential loss of control during flight. The directive specifically mandates that operators of the affected Beechcraft 400A aircraft must adhere to the outlined inspection procedures to comply with civil aviation safety standards. Failure to comply with the inspection requirements set forth in this directive may lead to serious consequences. The Civil Aviation Safety Authority (CASA) enforces strict penalties for non-compliance with airworthiness directives. While the specific penalties are not detailed in the directive, general civil aviation regulations outline potential penalties for breaches, which may include substantial fines, suspension or revocation of aircraft operating certificates, and possible criminal charges in severe cases. The exact penalties are determined based on the severity of the non-compliance and the risk posed to flight safety. In summary, the Civil Aviation Regulations 1998 mandate a stringent inspection process for the spoiler control push rods on Beechcraft 400A aircraft. Operators must conduct these inspections within 50 hours of the aircraft's time in service post-29 February 1996 to ensure compliance with safety standards. Non-compliance may result in severe penalties, highlighting the critical importance of adhering to these airworthiness directives to maintain aviation safety.
