Safety Recommendation: 2022-005
2022-005: It is recommended that the UK Civil Aviation Authority require ab initio pilots to undergo training in the management of partial power loss situations in single-engine fixed-wing aeroplanes.
The CAA has been addressing this safety recommendation within the context of the General Aviation Pilot Licensing & Training Simplification project, for which the most significant amendments came into force on the 1st October 2025. This followed several rounds of consultation and engagement with general aviation stakeholders related to both the UK Aircrew Regulations and UK Sailplane Regulations.
The amendments that came into force have now introduced managing partial power loss scenarios into the various respective syllabi for ab-initio pilots. Details of which can be found below.
Partial power loss can be found in Exercise 12/13 and Exercise 16 within the Part-FCL PPL(A) Training course in AMC1 FCL.210 PPL(A) Training course with additional guidance that has been provided in GM1 FCL 210 PPL(A) Training course. The Skill Test may now also include a simulated partial loss of power which is noted within GM1 FCL.235 Skill Test.
Additionally, within AMC1 FCL.210.A PPL(A) – Experience requirements and crediting, there is now focus to ensure that applicants for the PPL(A) with previous aeroplane, TMG or microlight experience receive partial power loss training as specified in the syllabus prior to the completion of the training course.
For the NPPL(A) training course. Partial Power Loss is covered in CAP3181 within Exercise 12/13 and 16 of the NPPL(A) SEP and TMG Syllabus and exercise 16a of the NPPL(A) Microlight Class Rating syllabus. For all class ratings that can be endorsed on the NPPL(A), simulated partial power loss may be included in the skill test. It should be noted that CAP3181 will be replaced during 2026 with a more comprehensive document for the NPPL(A) qualification.
For the SPL training course. Partial Power Loss has been introduced to ab-initio training for Self-Launching Sailplanes and Touring Motor Gliders.
For Self-Launching Sailplanes this is detailed in Exercise 11c Self-Launch AMC2 SFCL.130 SPL – Training course and experience requirements.
For TMGs this is detailed in Exercise 9/10e Emergencies within AMC1 SFCL.150(b) SPL – Sailplane and TMG privileges and GM1 SFCL.145 SPL - Practical skill test for the Skill Test.
Additional Guidance for Powered Sailplane Instructors is provided in GM1 SFCL.330 (b) FI(S) and BI(S) Training course.

This is an update on the actions being taken by the CAA to address the three safety recommendations listed above.
The CAA will consider these safety recommendations within the General Aviation Pilot Licensing & Training Simplification project, which will involve subject matter experts from licencing, instructors, examiners, as well as external GA stakeholders.
Phase 1 of the project recently concluded and established the overall strategic direction of the endeavour. Phase 2 is scheduled to begin this month and will explore amending the relevant pilot training syllabi to include managing partial power loss events. This has the potential to affect multiple ICAO and sub-ICAO initial pilot training courses including the National Private Pilot Licence (NPPL), Light Aircraft Pilot Licence (LAPL)/Private Pilot Licence (PPL) as well as the Commercial Pilot Licence (CPL), Multi-Pilot Licence (MPL) and Airline Transport Pilot Licence (ATPL) integrated courses.
For the revalidation of single-engine fixed-wing aeroplane class ratings there is a requirement to complete at least one hour of dual flight training. The purpose of the flight is to refresh the pilot’s understanding of threat and error management with special emphasis on decision-making as well as basic handling skills for normal and abnormal operations. CAA TrainingCom Autumn 2019 contained a suggested profile for refresher flights and included partial power loss exercises. The CAA will consider incorporating this in a new AMC applicable to the revalidation requirements.
Upon determining the appropriate changes to the relevant ab pilot training courses and rating revalidation training, the CAA will devise and promulgate guidance and safety promotion material for managing partial power loss situations.
The CAA will provide a further update by the end of Q4 2023.

The CAA is considering these safety recommendations within the context of the General Aviation Pilot Licensing & Training Simplification project. Phase 2 of the project is underway and is focussed on amending pilot licences, ratings, and certificates across multiple aircraft categories.
Several working group meetings took place earlier this year involving a range of subject matter experts who developed a series of detailed proposals, including amendments to the relevant pilot training syllabi to incorporate managing partial power loss events. The CAA considers that these proposals will address Safety Recommendation 2022-005 and they will be publicly consulted on in February 2024.
The GA Pilot Licensing & Training Simplification project will also address Safety Recommendation 2022-006. The aforementioned public consultation will propose some amendments to the revalidation and renewal requirements for aeroplane licence holders in order to include partial power loss exercises.
To address Safety Recommendation 2022-007, the CAA will develop and promulgate the necessary safety promotion material for managing partial power loss situations once the changes to the ab pilot training courses and rating revalidation training have been determined.
The CAA will provide a further update by the end of August 2024.AAIB Classification

The CAA is addressing these safety recommendations within the context of the ongoing General Aviation Pilot Licensing & Training Simplification project. In Spring 2024, we published a suite of five consultation papers with proposed changes to licenses and ratings across the different GA aircraft categories. The proposals were based on the output of a working group comprising key GA stakeholders, including associations, flying instructors and Private Pilot Licence (PPL) students.
The aeroplane category consultation (CAP 2335) included:
- a proposal to introduce training in the management of partial power loss events for ab-initio pilots, via the PPL(A) syllabus; and

There was clear support for introducing training in the management of partial power loss events for ab-initio pilots of single engine aeroplanes, and for this topic to be covered during the applicable biennial refresher training.
Phase 3 of the Pilot Licensing & Training Simplification project has now commenced and will focus on recommending legislative changes to the Department for Transport. The flight exercises applicable to ab-initio and refresher training in single engine aeroplanes are contained in AMC material. The CAA will be further developing and consulting on AMC material later in 2024 or early 2025 – finalising the material for partial power scenarios will form part of this work.
The CAA will also be developing and promulgating safety promotion material for managing partial power loss situations.
