South Africa’s 12-Year Engine Rule Finally Heads for the Gazette

By Garth Calitz

South Africa’s long-running general aviation battle over the so-called 12-year engine rule appears to be approaching a significant turning point. After years of consultation, debate, technical arguments, regulatory reviews, and enough paperwork to probably qualify as an aircraft component in its own right, the 36th Amendment to the Civil Aviation Regulations has finally been signed off by Transport Minister Barbara Creecy.

The Minister signed the amendment on 12 August 2026, according to information received by Flightline Weekly. The amendment is now expected to proceed to publication in the Government Gazette.

The next scheduled ordinary weekly Government Gazette is Friday, 21 August 2026, with the official publication timetable showing a submission deadline of 14 August for that issue. If Amendment 36 made that deadline, 21 August is therefore the expected publication date. The following Gazette is scheduled for 28 August.

For an industry that has spent years waiting for regulatory certainty, the significance is difficult to overstate. But, as anyone familiar with South African aviation regulation will know, a signature is not quite the same thing as a regulation taking effect.

There is still the small matter of the Gazette. Because apparently, even after the Minister has signed the paperwork, the paperwork itself still needs departure clearance.

A long-running problem

The dispute surrounding the 12-year engine requirement has been one of the most contentious issues in South African general aviation. The basic problem is relatively easy to understand.

An aircraft engine can accumulate comparatively few flying hours while reaching a calendar limitation. Under the existing regulatory framework, reaching that limitation can result in a significant maintenance requirement, potentially including an overhaul or other prescribed action. For owners of low-utilisation aircraft, the economic consequences can be substantial. An aircraft that may have flown only a few hundred hours since its last overhaul can nevertheless find itself on the wrong side of a calendar limitation.

The result has been aircraft being grounded or facing major expenditure even where owners believe there is a technically defensible case for continued operation based on the engine's actual condition.

This is where the argument becomes more complicated.

Nobody seriously argues that engines should be allowed to operate indefinitely simply because they have low hours.

• Age matters.

• Corrosion matters.

• Maintenance history matters.

• Operating conditions matter.

• Component condition matters.

The question is whether calendar age should automatically determine the outcome, regardless of all those other factors. That is the issue Amendment 36 is designed to address.

The 36th Amendment introduces changes involving Parts 43 and 91, together with the technical framework associated with Appendix 3 and the proposed Condition Monitoring Programme. The amendment is intended to address the long-running 12-year engine issue and provide a framework for condition monitoring of qualifying engines.

The significance of the change is that reaching the traditional calendar limitation would no longer necessarily mean that the only available option is an immediate overhaul. Instead, qualifying engines could potentially enter a Condition Monitoring Programme (CMP) under which their continued airworthiness is demonstrated through prescribed inspections, monitoring and maintenance.

In simple terms, the philosophy moves from:

“The engine has reached the calendar limit, therefore it must come out of service.”

towards:

“The engine has reached the calendar limit. Can its continued safe operation be demonstrated through an approved condition-monitoring system?

1. That is a substantial philosophical change.

2. It does not remove the importance of engine age.

3. It introduces another way of assessing risk.

4. It is not an automatic exemption

There is already considerable interest among aircraft owners who have watched perfectly serviceable aircraft become expensive lawn ornaments while the paperwork travelled through the regulatory machinery.

However, Amendment 36 should not be interpreted as an automatic exemption for every engine older than 12 years. That would be both inaccurate and potentially dangerous. The new system is expected to impose specific requirements relating to inspection, maintenance, records and ongoing monitoring.

An engine will still need to demonstrate that it is suitable for continued operation. The Condition Monitoring Programme should therefore be viewed as a regulated pathway, not a loophole. An engine with a poor maintenance history, corrosion, defects or other unacceptable conditions will not suddenly become airworthy because the Gazette has been published, and that is exactly how it should be.

The objective should be to remove an unnecessarily rigid requirement while maintaining — and preferably strengthening — the focus on actual aircraft and engine condition.

The regulator's role

This is where the story becomes slightly more interesting. The aviation industry has spent years arguing that the regulatory system needed to become more risk-based and technically focused. The regulator, meanwhile, has had to balance those arguments against its fundamental responsibility for aviation safety.

Nobody should expect the regulator simply to accept an owner's assertion that an old engine is “still good”. The condition-monitoring concept requires evidence. That means qualified maintenance personnel, appropriate inspections, accurate records and continuing compliance.

In fact, a properly implemented condition-based system could arguably place more responsibility on owners and maintenance organisations, rather than less. And that is where some of the industry's frustration with the process has been understandable.

After years of discussion, it has sometimes appeared that the regulatory machinery could move an aircraft engine from one committee to another with considerably less effort than the engine itself would need to move from Johannesburg to Pretoria. The irony is that aviation is supposed to be an industry built around movement.

The difference between approval and law

The Minister's signature on 12 August represents a major milestone, but aircraft owners should understand the distinction between ministerial approval and promulgation.

The process broadly consists of:

• Regulatory development: The proposed changes are developed, reviewed and subjected to the required consultation and regulatory processes.

• Ministerial approval: The Minister considers and signs the amendment.

• Gazette publication: The amendment is formally published in the Government Gazette.

• Commencement: The amendment then becomes effective in accordance with the commencement provisions contained in the published regulation.

SACAA's own legal notices demonstrate that ministerial approval and Gazette publication are separate stages. For example, SACAA records that the Minister approved and signed the 34th Amendment on 26 January 2026, after which the regulations were published for promulgation, with that amendment taking effect from 1 April 2026.

Consequently, owners should not unground their aircraft based solely on the expectation that Amendment 36 will appear on 21 August — nor should they return an aircraft to service until the final legal and technical requirements have been confirmed.

Why 21 August matters

The Government Gazette's schedule for 2026 shows that there's a regular weekly issue coming out on Friday, August 21, with submissions closing on August 14. The following issue is set for August 28. So, if Amendment 36 was submitted on time, August 21 is the likely publication date. However, it's best to call it an expected date rather than a guaranteed one until the Gazette is actually published.

Once published, the industry will finally have the definitive wording, and that wording matters. Very often, the devil is not merely in the detail.

In aviation regulation, the devil has a tendency to be hiding somewhere around paragraph 43.02.3(b), preferably behind three cross-references and an appendix.

What aircraft owners should do now...

Owners affected by the 12-year issue should use this period to prepare rather than simply wait. Aircraft and engine records should be brought up to date.

Owners should establish:

• the engine's total time;

• time since overhaul or other major maintenance;

• maintenance history;

• operating history;

• applicable manufacturer requirements;

• previous inspections;

• known defects or outstanding maintenance;

• component replacement history;

• The documentation required to demonstrate continued airworthiness.

It would also be sensible to discuss the proposed system with an appropriately authorised Approved Maintenance Organisation (AMO).

However, owners should avoid spending large amounts of money based on assumptions about what the final system will require. The sensible approach is to wait for the promulgated regulation and associated technical standards, then determine the exact compliance pathway for the particular engine.

What happens to grounded aircraft?

This is likely to be the most important practical question. Aircraft already affected by the 12-year limitation, publication of Amendment 36 may open a route towards continued operation — but it will not necessarily put those aircraft straight back into the sky. Each aircraft and engine will need to be considered individually.

The likely process will involve determining whether the engine qualifies for the Condition Monitoring Programme, carrying out the required inspections, confirming the engine's history and compliance, and establishing the ongoing monitoring regime. The AMO and appropriately authorised maintenance personnel will therefore play a central role.

The precise process will only become clear once the final regulatory wording and technical standards are available; that is why the Gazette publication is so important. Until then, there remains an element of aviation's favourite activity: waiting for paperwork.

A potential win for South African general aviation

If implemented properly, Amendment 36 could have consequences well beyond the individual engine. South Africa has a large and diverse general aviation sector supporting flying schools, private owners, charter operators, agricultural aviation, maintenance organisations, flying clubs and numerous aviation businesses. Keeping serviceable aircraft economically viable is important to the entire ecosystem, as we have noticed over the last 18 months. An unnecessarily rigid maintenance requirement can make older aircraft uneconomic to operate.

A properly controlled condition-based system could potentially extend the useful life of qualifying engines while still maintaining an appropriate level of safety assurance. That could mean fewer aircraft sitting idle, less unnecessary expenditure and greater utilisation of the existing fleet.

It could also help maintenance organisations focus resources where they are most needed — on identifying actual defects and managing real risks rather than simply responding to a calendar date.

Safety remains non-negotiable; there should be no misunderstanding about the objective. Amendment 36 should not become a battle between safety and cost. It should be about achieving both where the evidence allows it. If an engine is unsafe, it should not fly. If an engine has reached a point where an overhaul is genuinely required, it should be overhauled.

But if an engine has relatively low utilisation, an excellent maintenance history and can demonstrate continued airworthiness through an appropriately rigorous inspection and monitoring programme, there is a reasonable argument that calendar age alone should not automatically make it unairworthy. That is the fundamental principle behind the change.

For general aviation, the Minister's signature on 12 August 2026 is therefore a significant milestone. After years of debate and regulatory uncertainty, Amendment 36 has finally reached the point where its implementation appears to be within sight. The next scheduled Government Gazette publication is 21 August 2026, making that date one to watch closely, but the industry has learned not to celebrate too early.

The amendment may have received ministerial clearance, but until it appears in the Gazette and its commencement provisions are understood, there is still a final regulatory hurdle to clear. Perhaps appropriately, after all the discussion about aircraft engines being limited by the calendar, the industry now finds itself waiting on one more date.

If Amendment 36 appears as expected, the focus will immediately shift from when will it happen? to the much more useful question: “Exactly how do we make it work?” That will be the real test.

For aircraft owners who have watched their machines become expensive ornaments because a calendar reached a particular number, however, the Minister's signature is at least a reason for cautious optimism. And after years of regulatory holding patterns, that is probably progress.

The Minister has signed. The runway is clear. Now, hopefully, the paperwork gets airborne.
