Background:

The Civil Avia5on Safety Authority, through the Civil Avia5on Orders (CAO), enables RA-Aus to authorise its members to carry out maintenance on certain aircraJ.

As a candidate for the RAAus L1 Maintenance Authority, you should be familiar with the following Civil Avia5on Orders:

• CAO 95.10

• CAO 95.32

• CAO 95.55

These Civil Avia5on Orders outline exemp5ons applicable to RAAus members and aircraJ in rela5on the requirements described by a number of regula5ons, par5cularly CAR 4A, 4B, 4C and 4D which are concerned with maintaining VH registered aircraJ.

This study guide covers a range of subjects as well as ques5ons which may require you to refer to external manuals and documents to locate an answer.

At the end of this study guide, you will find a list of answers to these ques5ons.

Reference: RAAus Technical Manual, Version 4, Sec5on 11.1, 4.1

ANSWER:

DefectRepor?ngandAirworthinessNo?ces(ANs)

From 5me to 5me defects in aircraJ will be found. These defects may be the results of unexpected excessive wear, a design fault or some other factor. It is important that all defects be reported as soon as they are detected, the Technical Team can then review these reports and decide what ac5on should be taken. A Defect No5ce may also be submi]ed if an aircraJ manual or process is considered to be ineffec5ve or dangerous in its content.

If a serious defect is found, or an issue has been reported a number of 5mes, the Technical Manager may issue an Airworthiness No5ce (AN) to all aircraJ owners and maintainers. Through sharing informa5on, by submi_ng a defect no5ce, the chances of an accident or incident occurring to another aircraJ may be greatly reduced.

A similar system operates in General Avia5on (GA), the results of those defects may result in the manufacturer issuing a similar document known as an Airworthiness Direc5ve (AD) or a manufacturer’s Service Bulle5n.

Ques%on 21: If you find a defect, as defined in the Technical Manual, Sec%on 13.1, 3.2 how should you report it?

Reference: RAAus Technical Manual, Version 4, Sec5on 13.1, 3.2

Ques%on 22: Where will an aircra> owner or maintainer find informa%on rela%ng to the %ming of ac%ons raised in an AN?

Reference: RAAus Technical Manual, Version 4, Sec5on 13.1, 5.7

ANSWER:

ANSWER:

MaintenanceSchedules

AircraJ must be maintained by following an acceptable preventa5ve maintenance program, which is generally referred to as a maintenance schedule. The schedule will specify certain maintenance tasks, which must be completed to keep the aircraJ in a safe and airworthy state. Items included in the schedule may call for the overhaul or replacement of components or parts at specified intervals, these may be based on flight 5me or calendar 5me. Other items included in the schedule will call for the inspec5on of airframe and engine components, which may require cleaning, lubrica5on or replacement due to excessive wear, corrosion or general deteriora5on.

Maintenance schedules are normally incorporated in maintenance manuals produced by aircraJ and kit manufacturers and must be followed. Some older, factory built, and most amateur built aircraJ may not have maintenance manuals or schedules, these aircraJ are to be maintained in accordance with the RAAus Technical Manual schedule.

Maintenance manuals produced by manufacturers will normally provide detailed direc5ons on how to perform the various tasks contained in their schedules. In the absence of detailed direc5ons, and for aircraJ maintained in accordance with the RAAus maintenance schedules, more informa5on can be found by referring to the Federal Avia5on Administra5on (FAA) produced 43 series Advisory Circulars (ACs) for acceptable prac5ces. These ACs are generally adopted worldwide as being acceptable maintenance prac5ces for light aircraJ. The ACs are numbered 43-13A and 43-13B and are available for download from the FAA website or may be purchased from various pilot supply shops.

Below are examples of both manufacturer maintenance prac5ces and those of FAA AC 43-13:
