Plain English Summary

3/10 complexity

This instrument temporarily exempts certain aircraft from mandatory fuel gauge calibration requirements.

What it does: Normally, Civil Aviation Order 100.5 requires aircraft fuel quantity gauges to be calibrated. This determination says that Class A aircraft (generally larger commercial aircraft) are exempt from this requirement if they use a manufacturer-approved maintenance program based on modern international standards called MSG-2 or MSG-3.

Who it affects:

Operators of Class A aircraft
Aircraft using manufacturer maintenance programs approved by the national aviation authority that originally certified the aircraft type
These MSG programs are sophisticated, data-driven maintenance systems developed by manufacturers like Boeing or Airbus

Why it matters: This recognizes that modern aircraft using these advanced maintenance programs already maintain high safety standards through continuous monitoring and analysis, making separate fuel gauge calibration requirements redundant for these specific aircraft.

Determination – Civil Aviation Order 100.5 – non-application of fuel quantity gauge calibration requirements

1 Duration

This instrument:

(a) commences on the day after registration; and

(b) is repealed at the end of 31 October 2020.

2 Determination

(1)I determine that clause 6 of Appendix 1 to Civil Aviation Order 100.5 (General requirements in respect of maintenance of Australian aircraft) 2011 does not apply to a class A aircraft the approved system of maintenance for which incorporates a manufacturer’s MSG maintenance program.

(2) In subsection (1), manufacturer’s MSG maintenance program, for an aircraft, means the aircraft manufacturer’s program for the management of continuing airworthiness of the aircraft that:

(a) requires the carrying out of maintenance that was developed using the specification, known as “ATA MSG-2” or “ATA MSG-3”’, as the specification existed at the time the maintenance program was approved; and

(b) is approved by a national aviation authority that issued a type certificate for the aircraft.

Note 1 ATA MSG-2 and ATA MSG-3 are specifications presently published by the organisation known as Airlines for America, formerly known as the Air Transport Association of America (ATA).

Note 2 The term national aviation authority is defined in CASR by reference to a foreign country.
