Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105 and the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, address the safety concerns surrounding the Robinson R22 Series Helicopters. This legislation was introduced to address the problem of mast-bumping, a potentially dangerous condition that may arise during low-gravity cyclic pushover manoeuvres. The regulations were enacted to ensure the continued airworthiness and safety of these helicopters, thus protecting the lives of pilots and passengers. The policy objective is to mandate the installation of a placard prohibiting low-G pushovers in clear view of the pilots, alongside a necessary revision to the Flight Manual. This directive was issued by the Civil Aviation Safety Authority to ensure compliance with safety standards and to mitigate the risks associated with such manoeuvres. The Civil Aviation Regulations 1998, as amended through the legislative instrument F2006B06445, were enacted by the Commonwealth of Australia's Parliament. The regulations require Robinson R22 Series Helicopter operators to install a placard that explicitly states "LOW-G PUSHOVERS PROHIBITED" in a location where it is easily visible to the pilots. Additionally, a corresponding update to the Flight Manual must be made to reinforce this prohibition. This measure was introduced following a Federal Aviation Administration analysis that highlighted the risk of mast-bumping during low-gravity cyclic pushovers. The regulation aims to ensure the safety and airworthiness of the Robinson R22 Series Helicopters by strictly prohibiting these manoeuvres, thereby reducing the risk of accidents and enhancing overall flight safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Robinson R22 series helicopters within the Commonwealth of Australia. This regulation mandates that operators of these helicopters must install a specific placard in clear view of the pilots, stating "LOW-G PUSHOVERS PROHIBITED". The requirement ensures that the placard is large enough and placed in a location where it is easily readable by the pilots. Additionally, the Flight Manual of these helicopters must be revised to include the prohibition of low-G cyclic pushovers, with a reference to the FAA Priority Letter AD 95-11-09. Compliance with these directives is mandatory prior to any further flight after 7 June 1995, following an analysis by the FAA that identified the risk of mast-bumping during low-G cyclic pushover manoeuvres on the Robinson R22 helicopters. The regulation does not explicitly mention exclusions or thresholds, but compliance is necessary for all affected helicopters operating within the Australian jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, contain the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives, detailing requirements for maintaining the airworthiness of aircraft. In this context, AD/R22/40 pertains to the Robinson R22 series helicopters and mandates placards to prohibit pushovers (section 8/95DM). The requirement under this directive is to install a placard in the helicopter that states "LOW-G PUSHOVERS PROHIBITED" in a location and size that ensures it is clearly readable by the pilots (section 1). The specified placard in Robinson R22 SB 79 is deemed acceptable, while a Dymo tape style placard is not (section 1). Additionally, a revision to the Flight Manual is required, stating that "Low-G cyclic pushovers are prohibited," with a note referencing FAA Priority Letter AD 95-11-09 (section 2). The obligations imposed by this legislation on the parties or entities it governs are primarily centered around ensuring compliance with the specified placard installation and Flight Manual revisions. Operators and owners of Robinson R22 helicopters must ensure that the mandated placard is installed in a manner compliant with the regulations, with the correct wording and visibility as specified. Additionally, they are required to update their Flight Manuals to reflect the prohibition on low-G cyclic pushovers, providing clear guidance to pilots and maintaining operational safety standards. These requirements aim to mitigate risks associated with mast-bumping, a potential hazard identified in the aircraft's performance under low-gravity conditions. In terms of consequences for non-compliance, while the specific Civil Aviation Regulations 1998 do not explicitly state penalties for breaches of airworthiness directives such as AD/R22/40, non-compliance with CASA directives can lead to serious repercussions under the Civil Aviation Act 1988. Such breaches may result in enforcement actions, including fines, suspension or revocation of airworthiness certificates, and potential criminal charges in cases of gross negligence or willful disregard of safety regulations. The severity of penalties can vary, but they are intended to enforce adherence to safety standards and protect public safety in aviation operations.
