AD/SM-205/28 - Flap Control Lever - Inspection

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B07050, introduce specific airworthiness directives to address safety concerns related to the operation of certain aircraft. Enacted by the Commonwealth of Australia's Civil Aviation Safety Authority (CASA), this legislation focuses on the periodic inspection of flap control levers in SIAI Marchetti S205 and S208 series aeroplanes. This was introduced to ensure that the mechanical integrity and functionality of these critical components are maintained to prevent potential failures during flight. The policy objective is to enhance aviation safety by requiring regular maintenance checks, thus minimising the risk of in-flight incidents due to mechanical failures.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, apply to the Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA), specifically concerning SIAI Marchetti S205 and S208 series aeroplanes. This legislation mandates that all SIAI Marchetti models S-205/18F; S-205/18R, S205/20F, S-205/20R, S205/22R, which are equipped with manual flap control, must adhere to the AD/SM-205/28 directive concerning flap control lever inspections. The legislation applies to these specific aircraft models, requiring compliance with the inspection intervals stipulated within the SIAI Marchetti SB No. 205B47 document. This requirement applies within 25 hours of time in service after 10 November 1977, and subsequently, at intervals not exceeding 500 hours time in service. This regulation applies nationally across the Commonwealth of Australia and is enforced by CASA to ensure the continued airworthiness of these aircraft.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates certain safety directives for the SIAI Marchetti S205 and S208 series aeroplanes. Section 39.105(1) outlines an Airworthiness Directive (AD) for these aircraft models, detailing the requirement for regular inspections of the flap control lever. This AD is applicable to all SIAI Marchetti models S-205/18F, S-205/18R, S205/20F, S-205/20R, and S205/22R equipped with manual flap control, as documented in SIAI Marchetti SB No. 205B47. The directive specifies that the initial inspection must be conducted within 25 hours of the aeroplane's time in service after 10 November 1977, with subsequent inspections occurring at intervals not exceeding 500 hours of time in service. The obligations imposed by this Act include ensuring that the flap control lever is thoroughly inspected according to the specified schedule. Operators of these aircraft must maintain records of these inspections and ensure that any identified issues are addressed promptly and in accordance with the manufacturer's guidelines. Compliance with this directive is crucial to maintaining the airworthiness of the aircraft, as it directly affects the safe operation of the aeroplane's flap system. Failure to comply with the AD/SM-205/28 requirements may result in serious safety implications. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives. Section 39.105(3) stipulates that non-compliance may lead to enforcement actions, including the grounding of the aeroplane until the necessary inspections and repairs are completed. In more severe cases, the Civil Aviation Safety Authority (CASA) may impose administrative penalties, which can include fines and potential legal actions against the operators. The exact penalties are not specified in the document but are governed by the broader provisions of the Civil Aviation Act 1988 and related regulations.
