AD/PA-22/31 - Fire Hazard Prevention - Inspection and Rework

Overview

The Civil Aviation Regulations 1998, amended by the Legislative Instrument F2006B05436, address the critical issue of fire hazards associated with Piper PA-22 series aeroplanes, specifically the Tri-Pacer and Colt models. This amendment, enacted by the Commonwealth of Australia, was introduced to mitigate risks identified from prior incidents, including in-flight fires. The policy objective is to enhance aviation safety by requiring regular inspections and rework to prevent fire hazards. The regulation mandates that compliance with these safety directives be achieved within a specific timeframe following an in-flight fire and at regular intervals thereafter, ensuring ongoing safety standards are met. Enacted by the Parliament of the Commonwealth of Australia, this legislation under Part 39 of the Civil Aviation Regulations 1998 aims to rectify the identified gap in safety protocols for Piper PA-22 aeroplanes. The specific directive, AD/PA-22/31, outlines the necessary steps for inspection and rework as per Piper SB 161A, referencing FAA AD 57-22-1. This requirement is crucial in preventing potential fire hazards that could compromise the safety of air travel, aligning with the overarching goal of maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, pertains to the Piper PA-22 (Tri-Pacer and Colt) Series Aeroplanes and mandates compliance with AD/PA-22/31, which addresses fire hazard prevention through inspection and rework. This directive applies universally to all models of the specified Piper aircraft, making it imperative for all operators and owners to adhere to its requirements. The legislation mandates compliance within 25 hours time-in-service after 31 March 1985, and subsequently at intervals not exceeding 100 hours, referencing Piper Service Bulletin 161A and Federal Aviation Administration AD 57-22-1. This regulatory framework is established to mitigate fire hazards, ensuring the continued airworthiness and safety of the aircraft in question.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes AD/PA-22/31. This airworthiness directive pertains to the Piper PA-22 series aeroplanes, including the Tri-Pacer and Colt models, and mandates fire hazard prevention measures. The directive requires compliance with Piper Service Bulletin 161A, which is cross-referenced with FAA AD 57-22-1. The directive stipulates that all models must adhere to these requirements, with inspections and rework needed within 25 hours time-in-service following 31 March 1985, and then at intervals not exceeding 100 hours. The obligations under AD/PA-22/31 primarily focus on ensuring the fire safety of the Piper PA-22 series aeroplanes. Operators and owners of these aircraft are required to perform inspections and necessary rework to prevent in-flight fires, as specified in Piper SB 161A. This includes actions such as inspecting wiring, fuel system components, and other potential sources of ignition to ensure they meet the safety standards outlined in the service bulletin. Compliance with this directive is essential for maintaining the airworthiness of the aircraft and ensuring the safety of passengers and crew. Failure to comply with AD/PA-22/31 can result in serious consequences. The regulations outline penalties for non-compliance, which may include fines and other enforcement actions. Additionally, operating an aircraft that does not meet the requirements of this directive can lead to the aircraft being grounded, preventing it from being used until the necessary inspections and rework are completed. This can have significant operational and financial implications for the aircraft operator, emphasising the importance of adhering to the directive. The potential civil and criminal consequences for breaching AD/PA-22/31 can be severe. The Civil Aviation Safety Authority has the authority to take enforcement action against operators who fail to comply with airworthiness directives. This can include imposing fines, issuing compliance orders, or even prosecuting individuals or companies for breaches of the regulations. In more serious cases, criminal charges may be laid, leading to potential imprisonment. The maximum penalties for such offences can vary depending on the nature and severity of the breach, but they serve as a deterrent against non-compliance with safety regulations.
