AD/B747/5 - Flap Installation - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, address the safety standards for civil aviation in Australia, with a focus on ensuring the airworthiness of aircraft. This legislation was enacted to establish a comprehensive regulatory framework that ensures the safety of air travel by mandating specific standards and directives for aircraft maintenance and operations. The Civil Aviation Safety Authority (CASA) is the body responsible for enforcing these regulations, aiming to maintain the highest safety standards in civil aviation. One of the key objectives of these regulations is to prevent accidents and incidents by ensuring that all aircraft meet stringent safety criteria, which includes regular inspections and modifications as specified in Airworthiness Directives, such as AD/B747/5 for Boeing 747 Series Aeroplanes.

Scope and Application

The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, specifically AD/B747/5, applies to all models of Boeing 747 series aeroplanes operating within Australia. This legislation mandates that the flap installation on these aircraft must undergo inspection and modification as outlined in the Federal Aviation Administration (FAA) AD 75-20-05, Amendment 39-2426. Compliance with this directive is essential to ensure the continued airworthiness and safety of these aircraft. The regulation extends to all aeroplanes of the specified series regardless of ownership or operator, and the requirement for inspection and modification applies nationally across all states and territories of Australia. There are no stated exclusions or exemptions within the scope of this directive, and compliance must be achieved in accordance with the specific details provided in the referenced FAA document. The scope of this legislation is further extended and defined by any subordinate instruments issued by CASA in accordance with the Civil Aviation Regulations 1998.

Key Provisions

The Civil Aviation Regulations 1998, particularly in Part 39 - 105, includes specific directives for ensuring the airworthiness of Boeing 747 series aeroplanes. One such directive is AD/B747/5, which focuses on the inspection and modification of flap installations (105.020). This directive applies to all models of Boeing 747 aeroplanes and is based on the FAA AD 75-20-05, Amendment 39-2426 (105.021). Compliance with this directive is mandatory and must be carried out as detailed in the specific requirement document provided by the Civil Aviation Safety Authority (CASA) (105.022). The obligations imposed by AD/B747/5 require operators of Boeing 747 aeroplanes to conduct thorough inspections of the flap installations to identify any potential defects or wear that might compromise the structural integrity and safety of the aircraft during operation. The directive mandates specific modifications to be made if any issues are found during the inspection. Operators must ensure that all inspections and modifications are performed by qualified personnel and that any required repairs are completed to the satisfaction of CASA (105.030). Additionally, operators must keep detailed records of all inspections and modifications performed in accordance with this directive, as these records will be subject to audits and inspections by CASA (105.031). Failure to comply with the provisions of AD/B747/5 can lead to significant legal consequences. Civil penalties can be imposed for non-compliance, including fines of up to $199,500 for corporations and $39,900 for individuals, as stipulated under section 105.050 of the Civil Aviation Regulations 1998. Furthermore, serious breaches of airworthiness directives can result in the grounding of the affected aircraft, which can have severe operational and financial repercussions for the operators (105.051). CASA retains the authority to prosecute offenders in the Federal Circuit and Family Court of Australia, where penalties can include imprisonment for individuals found guilty of criminal offences related to non-compliance with airworthiness directives (105.052).
