Civil Aviation Regulations 1988

Directions  determining maximum weight (CGG Aviation)

 

Legislation

Section 98 of the Civil Aviation Act 1988 (the Act) provides that the Governor-General may make regulations for the Act and the safety of air navigation.

 

An aircraft’s certificate of airworthiness (CofA) or flight manual sets out its maximum takeoff weight (MTOW) or maximum landing weight (MLW). Under subregulation 235 (1) of the Civil Aviation Regulations 1988 (CAR 1988), CASA may give directions for estimating the gross weight of an aircraft, including passengers, cargo and fuel. For the safety of air navigation, CASA may give directions setting out the manner of determining, for an aircraft flight, the maximum weight, less than the MTOW or MLW, that the gross weight is not to exceed. Under subregulations 235 (4) and (6) of CAR 1988, it is an offence for the pilot in command to allow an aircraft to take off or land if its gross weight exceeds its MTOW or MLW.

 

For specified aeroplanes above 5 700 kg, CASA has given detailed directions in Civil Aviation Order 20.7.1B (CAO 20.7.1B). For certain aircraft not above 5 700 kg, CASA has given directions in Civil Aviation Order 20.7.4 (CAO 20.7.4).

 

Instrument

CGG Aviation (Australia) Pty Ltd (the operator), formerly Fugro Airborne Surveys Pty Ltd, operates a SC-7 Skyvan VH-WGT and a CASA 212 VH-TEM (the aircraft). When equipped for aerial survey work, each aircraft is above 5 700 kg. In that configuration, each aircraft is unable to comply with the weight limitations determined under CAO 20.7.1B.

 

Amendments to CAO 20.7.1B, in effect on and from 11 June 2005, removed the aircraft from the scope of CAO 20.7.1B which no longer applied to an aircraft with a CofA in the special or restricted category. Since the aircraft are both above 5 700 kg, CAO 20.7.4 also does not apply. However, CASA considers that it is necessary, in the interests of safety, to regulate the operations of these aircraft and has issued the operator with this instrument regarding the 2 aircraft.

 

CASA considers that it is safe for each aircraft to operate in compliance with CAO 20.7.4 in certain circumstances, but not, generally, in other adverse circumstances. The adverse circumstances are at night and below 1 000 feet in certain situations.

 

The instrument, therefore, directs that if a flight, landing or take-off (an operation) includes, or is likely to include, an adverse circumstance, the operation must, in effect, comply with CAO 20.7.1B. If an operation does not include, or is not likely to include, an adverse circumstance, the operation must, in effect, comply with CAO 20.7.4.

 

Specifically, there are 3 adverse circumstances: flight outside daylight; a take-off whose flight path involves flight below 1 000 feet AGL for more than 3 km over a city, town, populous or industrial area, or industrial plant (a restricted area); and a landing (except an emergency one) whose flight path involves flight below 1 000 feet AGL for more than 3 km over a restricted area.

 

There may be some circumstances where CASA considers that safety is not compromised by low-level flight for greater than 3 km over a restricted area. In such a case, CASA may approve the operation.

 

The instrument repeals CASA 152/14 which was issued to Fugro Airborne Surveys Pty Ltd, and reissues the direction to the operator with identical directions.

 

Legislative Instruments Act

Under subparagraph 6 (d) (i) of the Legislative Instruments Act 2003 (the LIA), an instrument is a legislative instrument for section 5 of the LIA if it is declared to be a disallowable instrument under legislation in force before the commencement of the LIA.

 

Under regulation 5A of CAR 1988, if CASA has issued a Civil Aviation Order (CAO), and CASA later issues a direction that affects the operation of that CAO, the later document is declared to be a disallowable instrument. This instrument affects the operation of both CAO 20.7.1B and CAO 20.7.4 in that the operator’s aircraft would not normally be required to either comply with CAO 20.7.1B or CAO 20.7.4, but under the direction would be required to comply with either CAO depending on the existence of an adverse circumstance. Therefore, the instrument is a legislative instrument subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LIA.

 

Consultation

At the request of the operator, this instrument repeals a previous instrument, CASA 152/14, and is reissued under the new business name of the operator for the same purpose. Given that the instrument applies to a particular operator and particular aircraft, it is CASA’s view that it is not necessary or appropriate to undertake any further consultation under section 17 of the LIA.

 

Statement of Compatibility with Human Rights

A Statement of Compatibility with Human Rights is at Attachment 1.

 

Office of Best Practice Regulation (OBPR)

A Regulation Impact Statement (RIS) is not required because the instrument is covered by a standing agreement between CASA and OBPR under which a RIS is not required (OBPR id: 14507).

 

Making and commencement

The direction has been made by a delegate of CASA relying on the power of delegation in subregulation 11.260 (1) of the Civil Aviation Safety Regulations 1998.

 

The direction commences on the day of registration and expires at the end of July 2016, as if it had been repealed by another instrument.

Civil Aviation Safety Authority

 

Overview

The Civil Aviation (Determining Maximum Weight) (CGG Aviation) Instrument 2014 was introduced to address the need for specific safety regulations for certain aircraft operated by CGG Aviation (Australia) Pty Ltd, formerly known as Fugro Airborne Surveys Pty Ltd. This legislative instrument was enacted under the authority of the Civil Aviation Act 1988 and the Civil Aviation Regulations 1988, with the Civil Aviation Safety Authority (CASA) as the enacting body. The primary policy objective of this instrument is to ensure the safety of air navigation by regulating the operations of specified aircraft, ensuring they comply with appropriate maximum weight limitations, particularly in adverse circumstances such as night flights or low-altitude operations over populated areas. By issuing this instrument, CASA aims to mitigate safety risks associated with the operation of these aircraft while providing flexibility where safety is not compromised. The instrument also considers human rights compatibility, affirming that it does not engage any applicable rights or freedoms.

Scope and Application

The Civil Aviation Regulations 1988, as amended by CASA Direction determining maximum weight (CGG Aviation), applies to CGG Aviation (Australia) Pty Ltd, specifically regarding the operation of two aircraft, VH-WGT and VH-TEM. These aircraft, when configured for aerial survey work, exceed a maximum take-off weight of 5,700 kg, placing them outside the scope of Civil Aviation Orders 20.7.1B and 20.7.4, which otherwise govern weight limitations. The regulation ensures that the safety of air navigation is maintained by stipulating specific conditions under which the aircraft can operate. In particular, the regulation mandates compliance with CAO 20.7.1B if the flight, landing, or take-off is likely to involve adverse conditions, such as flying outside daylight hours or below 1,000 feet above ground level over populated or industrial areas. Conversely, if such adverse conditions are not expected, the operation must comply with CAO 20.7.4. This instrument affects the operation of CAO 20.7.1B and CAO 20.7.4, making it a legislative instrument subject to disallowance under the Legislative Instruments Act 2003. The instrument is compatible with human rights, as it does not engage any of the applicable rights or freedoms.

Key Provisions

The primary sections of the Civil Aviation Regulations 1988 relevant to this legislation are section 98, which grants the authority to make regulations for the Act, and subregulations 235(1), 235(4), and 235(6). These sections empower the Civil Aviation Safety Authority (CASA) to issue directions regarding the estimation of an aircraft's gross weight and set maximum weight limitations for safety reasons. Specifically, subregulation 235(1) allows CASA to provide directions for estimating an aircraft's gross weight, while subregulations 235(4) and (6) criminalise the act of allowing an aircraft to take off or land if its gross weight exceeds the maximum take-off weight (MTOW) or maximum landing weight (MLW). The obligations imposed by this legislation on CGG Aviation (Australia) Pty Ltd are to ensure that their specified aircraft operate in accordance with the directions issued by CASA. The directions mandate that the aircraft must comply with either Civil Aviation Order 20.7.1B or Civil Aviation Order 20.7.4, depending on the operational circumstances. For instance, if a flight operation includes or is likely to include adverse conditions such as night flights or low-level flights over restricted areas, the aircraft must comply with CAO 20.7.1B. Conversely, if an operation does not include such adverse conditions, compliance with CAO 20.7.4 is required. CASA retains the discretion to approve operations in specific circumstances where safety is not compromised despite deviations from standard weight limitations. Breaches of the regulations outlined in this legislation can result in significant consequences. Under subregulations 235(4) and (6) of the Civil Aviation Regulations 1988, it is an offence for the pilot in command to allow an aircraft to take off or land if its gross weight exceeds its MTOW or MLW. The penalties for these offences can include substantial fines and potential imprisonment, underscoring the importance of adhering to the specified weight limitations for the safety of air navigation. Given the serious nature of these potential consequences, compliance with CASA's directions is crucial for the operator. This legislation also addresses the procedural aspects of its implementation and oversight. It is declared as a disallowable instrument under the Legislative Instruments Act 2003, which means it is subject to tabling and disallowance in the Parliament. The instrument's issuance follows consultation with the operator, who requested the repeal of a previous direction and its reissue under the new business name. Additionally, a Statement of Compatibility with Human Rights has been provided, affirming that the legislative instrument does not engage any of the applicable rights or freedoms under the Human Rights (Parliamentary Scrutiny) Act 2011.
