AD/BEECH 90/34 Amdt 1 - Strobe Light Bonding Straps - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form a critical part of the legislative framework governing aviation safety across the nation. Specifically, Part 39 - 105 of these regulations, which pertains to the Schedule of Airworthiness Directives, addresses the identification and rectification of safety deficiencies in aircraft through Airworthiness Directives (ADs). These ADs are imperative for ensuring that aircraft maintain an acceptable level of safety throughout their operational life. The enactment of this legislation aims to fill critical gaps in aviation safety by providing mandatory safety instructions and compliance deadlines for aircraft operators and maintenance personnel. One such Airworthiness Directive is AD/BEECH 90/34 Amendment 1, which applies to all Beechcraft 90 and 65-90 (King Air) series aeroplanes, specifically those with serial numbers and strobe light assembly specifications as detailed. This directive mandates the modification of strobe light bonding straps to mitigate identified safety risks, with compliance required within 100 hours of time in service after 31 January 1975. The policy objective underpinning these regulations is to enhance aviation safety by ensuring that aircraft remain airworthy through timely and effective implementation of safety measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority's schedule of airworthiness directives, governs the modifications required for the Beechcraft 90 and 65-90 (King Air) series aeroplanes. This legislation applies to all models C90 with serial numbers ranging from LJ-502 to LJ-643 and E90 with serial numbers from LW-1 to LW-117, provided they are fitted with Grimes part numbers 30-0467-1 or 30-0467-3 strobe light assemblies. Compliance with this directive must be achieved within 100 hours of time in service after 31 January 1975, ensuring that the specified modifications are implemented to maintain airworthiness standards. The directive is referenced in Beechcraft Service Instruction No. 0655-362, Rev. 1, which serves as the authoritative document for the required modifications.

Key Provisions

The Civil Aviation Regulations 1998 (Cth) under PART 39 - 105, specifically in the context of the Civil Aviation Safety Authority Schedule of Airworthiness Directives for the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, mandates certain modifications and compliance criteria in Section AD/BEECH 90/34 Amendment 1. This section applies to all models of the Beechcraft C90 and E90, with specific serial numbers (LJ-502 to LJ-643 for C90 and LW-1 to LW-117 for E90) that are equipped with Grimes P.N 30-0467-1 or Grimes P/N 30-0467-3 Strobe Light Assemblies. The compliance requirement stipulates that these modifications must be undertaken within 100 hours of the aircraft's time in service after 31 January 1975. The modifications are detailed in Beechcraft Service Instruction No. 0655-362, Revision 1. Under this regulation, the parties involved, primarily the aircraft operators and maintenance providers, are obligated to ensure that the specified modifications to the strobe light bonding straps are completed within the prescribed timeframe. This includes conducting a thorough inspection to ascertain the aircraft's eligibility for the modification and executing the required alterations as per the manufacturer's guidelines outlined in the referenced service instruction. The compliance with these directives is critical to maintaining the aircraft's airworthiness and ensuring adherence to safety standards set by the Civil Aviation Safety Authority. Failure to comply with the provisions outlined in AD/BEECH 90/34 Amendment 1 could result in serious legal and safety ramifications. The Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance within the provided text, but generally, breaches of airworthiness directives can lead to severe consequences. These may include fines, operational restrictions, or even the grounding of the aircraft. The severity of the penalties can vary, but they are intended to enforce strict adherence to safety standards to protect public safety and ensure the integrity of the aviation system.
