AD/PA-34/1 - Compass Installation - Inspection for Accuracy

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, address the critical aspect of ensuring the safety of civil aviation through the Civil Aviation Safety Authority's schedule of airworthiness directives. Enacted by the Australian Parliament, these regulations aim to safeguard the public by enforcing stringent safety standards across the aviation sector. The legislative instrument F2006B05880, pertaining to the Piper PA-34 (Seneca) Series Aeroplanes, was introduced to address the specific problem of ensuring accurate magnetic compass readings, particularly in critical flight conditions such as Instrument Flight Rules (IFR) operations. This directive mandates an inspection of the primary magnetic compass to ensure its deviation does not exceed 10 degrees under specified electrical load conditions, thereby maintaining the airworthiness of the aircraft and enhancing flight safety. The policy objective of this legislative instrument is to prevent navigational errors that could potentially lead to accidents, by enforcing regular and rigorous inspections of the compass system in Piper PA-34 (Seneca) Series Aeroplanes. By requiring compliance before the issuance of a Certificate of Airworthiness, the regulation ensures that aircraft meet the necessary safety standards, thereby protecting both the occupants and the general public from the risks associated with compromised navigational accuracy.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Piper PA-34 (Seneca) Series Aeroplanes, more precisely to model PA34-200. This regulation mandates that a primary magnetic compass must be inspected to ensure that its deviation does not exceed 10 degrees when electrical loads required for IFR flight are operated on battery power with both alternators inoperative. This inspection is a prerequisite for the issuance of a Certificate of Airworthiness. The regulation is a part of the Australian Commonwealth's legislative framework, thereby holding nationwide jurisdictional reach. The regulation is inclusive of all entities operating PA34-200 model aircraft within Australia and does not specify any exclusions or exemptions. The application of this regulation may be further defined or extended through subordinate instruments, ensuring that safety standards are consistently maintained across the industry.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, which pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, includes AD/PA-34/1 concerning the Piper PA-34 (Seneca) series aeroplanes. This directive mandates that the primary magnetic compass of the aircraft must be inspected to ensure that its deviation does not exceed 10 degrees when electrical loads necessary for Instrument Flight Rules (IFR) flight are operated on battery power, assuming both alternators are inoperative (AD/PA-34/1, 5/72). The requirement is to carry out this inspection before issuing a Certificate of Airworthiness (AD/PA-34/1, 5/72). The regulations impose specific obligations on the owners and operators of Piper PA-34 (Seneca) series aeroplanes. They must ensure that the primary magnetic compass is inspected and meets the stated accuracy requirement before the aircraft is considered airworthy and before a Certificate of Airworthiness is issued (AD/PA-34/1, 5/72). This involves conducting a thorough inspection to verify that the compass deviation does not exceed the specified limit under the conditions outlined in the directive. Failure to comply with AD/PA-34/1 may result in serious consequences. Non-compliance with this directive could lead to the aircraft not meeting the airworthiness standards required by CASA. Such failure could result in the Certificate of Airworthiness not being issued or being revoked, potentially rendering the aircraft ineligible for operation under IFR. The precise legal or civil penalties are not detailed in the directive itself but could include fines, operational restrictions, or other regulatory actions as determined by CASA.
