AD/BEECH 35/11
Amdt 2
Spar Truss 8/81
Applicability: Models 35 and 35R with S/Nos. D1 to D1500.
Requirement: 1. Provide five access doors in the fuselage skin below the mainplane forward truss assembly in accordance with Beech SB Model 35 (35R) No. 24, revised 5 November 1963.
2. Inspect the mainplane centre section front and rear spar truss assemblies in accordance with Beech SB Model 35 (35R) No. 24, revised 5 November 1963. For aircraft modified in accordance with FAA STC SA222CE (Mainplane Centre Section Reinforcement), inspect in accordance with STC SA222CE installation instructions Sheet 3.
Note: FAA AD 63-25-1 also refers.
Compliance: For Para 1. Prior to the first inspection in accordance with this Directive.
For Para 2. Prior to issue or renewal of Certificate of Airworthiness and thereafter:
(a) For aircraft modified in accordance with STC SA222CE -at intervals not exceeding 1000 hours time in service, or three years, whichever occurs sooner.
(b) For all other aircraft - as specified in Beech SB Model 34 (35R) No. 24 revised 5 November 1963, or at intervals not exceeding three years, whichever occurs sooner.
Background: This Directive has been revised to allow extended inspection intervals for aircraft fitted with wing centre section reinforcement modification to FAA STC SA222CE.
Overview
The Civil Aviation Regulations 1998, as part of the broader legislative framework overseen by the Civil Aviation Safety Authority (CASA), introduce detailed directives to ensure the safety and airworthiness of aircraft operating in Australian airspace. Specifically, AD/BEECH 35/11 Amendment 2 addresses the structural integrity of Beechcraft 35 (Bonanza) Series Aeroplanes, particularly focusing on the spar truss assemblies. This amendment was enacted to address the need for enhanced inspection protocols and structural modifications to ensure safety, particularly for aircraft with certain serial numbers and modifications. The policy objective is to maintain a high standard of aircraft safety by requiring specific modifications and inspections, thereby mitigating the risk of structural failure in these aircraft.
The legislative instrument aims to streamline and standardise the compliance requirements for these aircraft, ensuring that they meet necessary safety standards through defined inspection intervals and structural modifications. The CASA’s role is pivotal in enforcing these regulations to protect public safety and uphold the integrity of civil aviation within Australia.
Scope and Application
The Civil Aviation Safety Authority's regulation AD/BEECH 35/11 Amendment 2 pertains specifically to Beechcraft 35 (Bonanza) Series aeroplanes, namely models 35 and 35R with serial numbers D1 to D1500. This directive establishes requirements for structural modifications and inspections of these aircraft to ensure compliance with airworthiness standards. The regulation mandates the installation of five access doors in the fuselage skin below the mainplane forward truss assembly and stipulates inspections of the mainplane centre section front and rear spar truss assemblies, referencing specific service bulletins and technical standards. Compliance with these directives is necessary before the first inspection and before the issue or renewal of a Certificate of Airworthiness, with specified intervals for subsequent inspections depending on whether the aircraft has undergone a particular modification. The regulation allows extended inspection intervals for aircraft that have been modified according to FAA STC SA222CE. This regulation applies nationally under the Commonwealth of Australia's jurisdiction and is enforced by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate that Beechcraft 35 (Bonanza) Series Aeroplanes with serial numbers D1 to D1500 must comply with Airworthiness Directive AD/BEECH 35/11 Amendment 2 concerning the spar truss (section 1). The directive requires the installation of five access doors in the fuselage skin below the mainplane forward truss assembly, in accordance with Beech SB Model 35 (35R) No. 24, revised on 5 November 1963. Additionally, it requires inspections of the mainplane centre section front and rear spar truss assemblies, again following the guidance in the same service bulletin, or if the aircraft has been modified under FAA STC SA222CE, the inspection should be carried out according to the STC SA222CE installation instructions Sheet 3. The Federal Aviation Administration's AD 63-25-1 is also referenced.
The obligations imposed by this legislation are clear and require adherence to specific procedures to maintain airworthiness. Operators must ensure the installation of the specified access doors before conducting the first inspection as per the directive (section 2). For the inspection requirements, operators must inspect the spar truss assemblies before issuing or renewing the Certificate of Airworthiness and subsequently follow the stipulated intervals. For aircraft modified under FAA STC SA222CE, inspections must be performed at intervals not exceeding 1000 hours of time in service or three years, whichever comes first. For all other aircraft, inspections must be conducted as specified in Beech SB Model 34 (35R) No. 24 revised on 5 November 1963, or at intervals not exceeding three years, whichever is sooner.
Failure to comply with the provisions of AD/BEECH 35/11 Amendment 2 can result in serious legal and operational consequences. The Civil Aviation Safety Authority may take enforcement action against non-compliance, which can include fines, suspension or revocation of the Certificate of Airworthiness, and other penalties as prescribed by the Civil Aviation Act 1988. The exact penalties and enforcement measures are not detailed within the directive itself but are governed by the broader regulatory framework under which the Civil Aviation Safety Authority operates.
