Overview

The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide a comprehensive regulatory framework for civil aviation in Australia, ensuring the safety and efficiency of aviation operations. One of the key components of this framework is the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are intended to address specific safety issues identified with certain aircraft or aeronautical products, as illustrated by AD/PA-46/30 concerning the Piper PA-46 (Malibu) Series Aeroplanes. This particular AD was introduced in response to reports of failures in the flap drive bellcrank assemblies, which could potentially lead to a loss of control of the aircraft. The policy objective of the AD is to mandate inspections and repairs to ensure the safe operation of the affected aircraft models. Compliance with these directives is mandatory, and failure to adhere to the specified requirements can result in severe penalties.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, details an Airworthiness Directive (AD) issued by a delegate of the Civil Aviation Safety Authority (CASA) to address identified safety issues in certain Piper PA-46 (Malibu) series aeroplanes. The directive applies to specific models and serial numbers of the aircraft, mandating inspections and repairs to the left and right inboard flap drive bellcrank assemblies, which must be carried out according to Piper Service Bulletin No. 1062 dated 11 May 2001. Any assemblies found to have incomplete or inadequate welding must be replaced before further flight, in accordance with the applicable maintenance manual. This AD is in response to reported failures of the flap drive bellcrank assemblies, which could potentially lead to a loss of control of the aircraft. The directive requires compliance within 10 hours of time in service after 29 June 2001, unless the required action has already been completed. The AD became effective on 29 June 2001 and was published in the Commonwealth of Australia Gazette on the same date.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, Section 105, mandate the issue of Airworthiness Directives (AD) by a delegate of the Civil Aviation Safety Authority (CASA) to address identified safety issues. Section 39.1(1) provides the authority for CASA to issue these directives, which are binding legal requirements for maintaining the airworthiness of aircraft. Specifically, AD/PA-46/30 pertains to Piper PA-46 (Malibu) series aeroplanes and mandates the inspection and replacement of specific flap drive bellcrank assemblies. The applicability of this directive (Section 105) covers certain serial numbers of the PA-46-310P, PA-46-350P, and PA-46-500TP models. The requirement section specifies that the left and right inboard flap drive bellcrank assemblies, identified by Piper part numbers 82905-2 and 82905-3, must be inspected in accordance with Piper Service Bulletin No. 1062 dated 11 May 2001. Any assembly found to have incomplete or inadequate welding must be replaced before further flight, following the applicable maintenance manual. The AD imposes specific obligations on aircraft operators and maintenance personnel. Operators of the affected Piper PA-46 series aeroplanes must ensure that the specified inspections and replacements are conducted within the stipulated timeframe. This includes conducting the inspections as per Piper Service Bulletin No. 1062 and ensuring that any defective parts are replaced in accordance with the maintenance manual. Maintenance personnel must perform these inspections and repairs competently, adhering to the detailed instructions provided in the service bulletin and maintenance manual. The directive also requires that these actions are completed within 10 hours of time in service after 29 June 2001, unless already accomplished. Failure to comply with the requirements of this AD can result in severe consequences. The primary concern is the potential for unsafe conditions that could lead to the failure of the flap control system, resulting in a loss of control of the aircraft. Under the Civil Aviation Act 1988, non-compliance with an Airworthiness Directive can be considered an offence. The maximum penalty for such an offence can include substantial fines and imprisonment, reflecting the seriousness of neglecting safety directives. Additionally, non-compliance can result in the grounding of the affected aircraft until the required actions are completed, potentially disrupting operations and leading to further financial and logistical consequences for the operator.
