Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B02392, play a critical role in ensuring the safety and airworthiness of aircraft within Australian airspace. This specific Airworthiness Directive (AD), issued under the authority of the Civil Aviation Safety Authority (CASA) and effective from 16 May 2002, addresses a safety concern identified in Mystère Falcon 50 and Falcon 50 EX aeroplanes. The AD mandates that certain actions be taken to rectify potential wiring issues related to the optional cockpit lighting, as identified in Dassault Aviation Service Bulletin (SB) F50-318. The directive was introduced to mitigate the risk of unsafe wiring configurations that could potentially compromise the aircraft's electrical system and overall safety. CASA's policy objective is to enforce stringent safety standards and ensure that all aircraft meet the necessary regulatory requirements to operate safely.

Scope and Application

The Airworthiness Directive (AD) specified under the Civil Aviation Regulations 1998 applies to all Mystère Falcon 50 and Falcon 50 EX aeroplanes with serial numbers 2 through 270 inclusive, provided that Dassault Aviation Service Bulletin (SB) F50-318 dated 6 February 2002 has not been incorporated. This regulation is issued by the Civil Aviation Safety Authority (CASA) and is aimed at ensuring the safety of these specific aircraft types by addressing potential unsafe conditions identified in their cockpit lighting wiring configurations. The AD mandates the inspection and, if necessary, the modification of the aeroplanes' optional lighting wiring as per SB F50-318, to mitigate risks associated with incorrect wiring that could directly feed from the battery without a circuit breaker. The AD became effective on 16 May 2002, and compliance with the specified requirements must be achieved within 13 months from this date. This directive underscores CASA's commitment to maintaining high safety standards in civil aviation, with a specific focus on rectifying identified safety concerns in targeted aircraft models.

Key Provisions

The Civil Aviation Regulations 1998 (CAR 1998) under Part 39, Section 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. The Airworthiness Directive (AD) issued under this regulation, AD/AMD 50/25, pertains to the cockpit lighting of Mystère Falcon 50 and Falcon 50 EX aeroplanes (section 1). Specifically, it applies to all aircraft of these models with serial numbers 2 through 270, excluding those that have incorporated Dassault Aviation Service Bulletin (SB) F50-318 dated 6 February 2002 (section 2). The AD mandates that operators of these aircraft check and, if necessary, correct the wiring configuration of the optional lighting in accordance with SB F50-318 (section 3). If the wiring is found to be incorrect, it must be modified as per SB F50-318 Part 2. The directive is in response to a potential safety issue identified by Dassault, where certain optional lighting wiring may be incorrectly wired, potentially bypassing the circuit breaker and being directly connected to the battery. This poses a risk to the aircraft's electrical system integrity and safety. Operators of the affected aircraft must comply with the AD within 13 months from its effective date, 16 May 2002 (section 4). The compliance entails conducting a thorough inspection of the aircraft's optional lighting wiring to ensure it adheres to the specifications outlined in SB F50-318. If discrepancies are found, the wiring must be corrected to meet the required configuration. This requirement ensures that the aircraft maintain the necessary safety standards, reducing the risk of electrical failures or fires due to improper wiring. The AD is designed to address a known issue that could potentially compromise the safety of the aircraft during operation. Failure to comply with the AD may result in the aircraft being considered unairworthy, which could lead to enforcement actions by CASA. Under CAR 1998, non-compliance with ADs can result in civil or criminal penalties. Specifically, the Civil Aviation Act 1988 outlines the potential consequences for breaches of airworthiness directives, which may include fines and imprisonment. The exact penalties depend on the severity of the breach and are determined by the courts. CASA may also take additional enforcement actions, such as grounding the aircraft until the required modifications are made, to ensure compliance and maintain the highest safety standards in civil aviation. Operators are therefore obligated to adhere strictly to the AD to avoid any legal repercussions and ensure the continued airworthiness of their aircraft.
