CHAPTER 22 EQUIPMENT
22.01 Application
(1) Unless it provides otherwise, this Chapter applies to the following operators:
22.02 Purpose
This Chapter prescribes requirements for the purposes of subregulation 138.465 (2).
22.03 Approval of equipment
(1) Before a registered aircraft begins a flight, any equipment that is required to be fitted to, or carried on, the aircraft for the operation under a Part of the CASR or under this Chapter, must be compliant with the requirements of, or approved under, Part 21 of CASR.
(2) Subsection (1) does not apply to survival equipment, including signalling equipment, carried under section 22.08.
(3) Before a foreign-registered aircraft begins a flight in Australian airspace, the equipment required by this Chapter to be fitted to, or carried on, the aircraft must have been approved by the NAA of the aircraft’s State of registry.
(4) If equipment is fitted to, or carried on, an aircraft although not required by this Chapter to be so fitted or carried, then:
(a) the equipment need not have been compliant with the requirements of, or approved under, Part 21 of CASR; and
(b) for a foreign-registered aircraft — the equipment need not have been approved by the NAA of the aircraft’s State of registry; and
(c) no information provided by the equipment may be used by the flight crew to comply with any requirement of this Chapter in relation to equipment that is required to be fitted or carried for communications or navigation; and
(d) the equipment, whether functional or otherwise, must not at any time affect the safety of the operation or the airworthiness of the aircraft.
22.04 Visibility and accessibility of equipment
(1) This section applies in relation to equipment that is required for the operation under a Part of the CASR or under this Chapter, to be fitted to, or carried on, an aircraft.
(2) Equipment that is required for a pilot’s manual or visual use in, or from, the cockpit must be visible to, and usable by, the pilot from the pilot’s seat in the aircraft.
(3) Emergency equipment that is required to be fitted to, or carried on, an aircraft for a flight must be easily accessible for immediate use in the event of an emergency.
(4) Unless the contrary intention appears in a particular provision:
(a) a reference to a pilot seeing or viewing anything from a pilot’s seat is taken to mean that the thing is seen or viewed from the pilot’s normal sitting position in the seat; and
(b) any mention of feet (or ft) in the context of an altitude is taken to mean feet above mean sea level (AMSL), unless otherwise stated.
22.05 Serviceability of equipment
Any equipment required by this MOS to be fitted to, or carried on, an aircraft for a flight must be operative unless:
(a) another provision of the civil aviation legislation provides otherwise; or
> Note 1 A minimum equipment list (a MEL), approved under regulation 91.935, can only permit equipment required to be fitted to, or carried on, an aircraft by this MOS, to be unserviceable within the limits of the requirements contained in this MOS. An example from the Part 91 MOS is that section 26.26 of that MOS contains an allowable time period of 72 hours related to flights with inoperative altitude alerting equipment. An MEL would not be approved if it contained a maximum time period for altitude alerting equipment to be inoperative that was greater than the time period specified by either a master minimum equipment list (MMEL) or the applicable civil aviation legislation.
> Note 2 For civil aviation legislation, see section 3 of the Civil Aviation Act 1988.
(b) the equipment:
(i) is inoperative because of a defect that has been approved as a permissible unserviceability for the aircraft for the flight in accordance with regulation 21.007 of CASR; and
(ii) is fitted or carried in accordance with the permissible unserviceability.
22.06 Usage monitoring system requirements
(1) This section applies to a rotorcraft conducting an aerial work operation if it is required by the civil aviation legislation to be fitted with a usage monitoring system.
(2) The rotorcraft must be fitted with a usage monitoring system which:
(a) is continuously operating when the rotorcraft is operational; and
(b) records and stores data related to the rotorcraft’s time-in-service, engines, transmission and rotor systems.
(3) The usage monitoring system must reliably, accurately and comprehensively record data which when downloaded will show the following:
(a) time-in-service;
(b) operational parameters for the critical engine, and the transmission and rotor systems;
(c) all exceedances of the operational parameters mentioned in paragraph (b).
(4) The usage monitoring system must have a capability to retain all of the recorded data mentioned in subsection (3), whether for a single flight or a series of flights, until the data can be downloaded and safely stored by the operator for use, as necessary, in managing the aircraft’s continuing airworthiness requirements.
22.07 Searchlights and intercommunication system for aerial work operations at night
(1) The pilot in command of a rotorcraft conducting an aerial work operation that is an SAR operation at night that involves winching and rappelling must not conduct the operation unless the rotorcraft is equipped in accordance with the requirements of this section.
(2) For a winch and rappelling operation at night, the rotorcraft must be equipped with the following:
(a) at least 1 searchlight (the main searchlight) that may be operated, and trained in azimuth and elevation, by the pilot in command whose hands remain on the flying controls;
(b) at least 1 additional searchlight that may be safely operated, and would provide adequate hover reference, if the main searchlight becomes unserviceable;
(c) an intercommunication system, compliant with the requirements of, or approved under, Part 21 of CASR, that permits continuous communication between all flight crew members, air crew members, and task specialists on board the rotorcraft during the operation.
(2A) Despite paragraph 22.07 (2) (c), the intercommunication system is not required to permit continuous communication between all flight crew members, air crew members, and a task specialist (a relevant task specialist) who is:
(a) in the rotorcraft, or outside the aircraft, and about to be, or in the process of being, winched; or
(b) about to rappel, or in the process of rappelling; or
(c) in the aircraft, but for whom the safe performance of their function does not require such continuous communication;
provided that the operator’s operations manual has procedures to be followed for effective communication between the flight crew members, the air crew members and the relevant task specialist.
(3) At least one of the searchlights mentioned in subsection (2) must be a visible‑spectrum searchlight.
(4) If infrared technology is fitted as one of the searchlights mentioned in subsection (2) — the rotorcraft landing light must be positioned to provide hover cues in the event that the visible-spectrum searchlight becomes unserviceable.

22.08 Carriage of survival equipment etc.
(1) Before an aircraft begins an aerial work operation, the aerial work operator must ensure that the aircraft complies with subsection (2).
(2) The aircraft must carry such serviceable survival and signalling equipment as is reasonably appropriate for each person onboard the aircraft, in the event of a forced landing, to survive the surface conditions of any area over which the operation will be conducted.
(3) Subsection (1) does not apply if:
(a) throughout the operation, the pilot in command is able to maintain continuous radio contact with:
(i) ATS; or
(ii) the aircraft operator, or the operator’s representative; or
(b) the aircraft’s position is continuously monitored on the ground through an automatic continuous tracking system fitted to the aircraft.
22.09 Minimum equipment for NVIS incendiary dropping, NVIS fire mapping and NVIS firebombing
(1) For NVIS incendiary dropping, an aircraft must be equipped with the following:
(a) an NVIS incendiary dropping device (including its associated systems), approved in writing by CASA, which meets at least the specifications set out in an NVIS incendiary dropping device airworthiness bulletin published by CASA for this provision, and as in force from time to time;
(b) fittings and mountings for the NVIS incendiary dropping device, and its directly associated systems, that have design approval under Subpart 21.M of CASR;
(c) 1 standby attitude indicator installation that complies with the requirements set out in column 2 of item 6 of Table 26.12 (7) in the Part 91 MOS.
(2) For NVIS fire mapping, an aircraft must be equipped with the following:
