Accident G-BBSA

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 is addressing these safety recommendations within the context of the ongoing General Aviation Pilot Licensing & Training Simplification project. In Spring 2025, we published three consultation papers for the Acceptable Means of Compliance (AMC) and Guidance Material (GM) related to proposed changes to the Aircrew, Sailplane and Balloon Regulations respectively. The AMC/GM proposals followed the Phase 2 implementing rule consultation in Spring 2024 and working groups comprising key GA stakeholders, including associations, flying instructors and student pilots, where there was clear support for introducing training in the management of partial power loss events for ab-initio pilots of single engine aeroplanes/powered sailplanes, and for this topic to be covered during the applicable biennial refresher training. Further details including the Phase 2 Consultation Response Documents can be found on the dedicated project webpage Licensing & training simplification | UK Civil Aviation Authority.

The aeroplane category AMC/GM consultation (CAP 3094) included:

• The proposed PPL(A) training syllabus in FCL.210, including the management of partial power loss events for ab-initio pilots. This included Partial Power loss being featured for Engine Failure after Take-off in Exercise 12/13- Emergencies as well as Exercise 16 where partial power loss could be encountered in an enroute phase of flight.
• Additionally, within the proposed FCL.210- Experience requirements and crediting, there is 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.
• A revised Acceptable Means of Compliance (AMC) applicable to FCL.740 the biennial “refresher training” for the SEP, TMG and microlight class ratings that would include partial power loss as a recommended exercise.

The sailplane category AMC/GMC consultation (CAP3093) included:

• The proposed SPL training syllabus in AMC for SFCL.130 and SFCL.150 (b) introduces training on partial power loss related to Self Launching Sailplanes and Touring Motor Gliders respectively. Guidance material was also proposed for partial power loss involving self-sustaining sailplanes.
• The proposed skill test schedule in AMC SFCL.145 includes simulated partial power loss for Self-Launching Sailplanes and Touring Motor Gliders.

The aeroplane consultation ran for a period of 6 weeks earlier this year and received 95 responses in the aeroplane category. There was clear support for introducing the training in the management of partial power loss events for ab-initio pilots of single engine aeroplanes, for this topic to be covered during the applicable biennial refresher training and for further training to be considered when crediting previous experience towards the issue of a licence.

The sailplane consultation ran for a period of 6 weeks earlier this year and received 479 responses. There was clear support for introducing the training in the management of partial power loss events for ab-initio pilots of sailplanes and for this topic to be covered in the skill test for self-launching sailplanes and touring motor gliders.

The AMC and GM which will be supplementary to the main implementing rule changes to the regulation, are all planned to come into force during Q4 2025.

Since the end of the AMC/GM consultation, the CAA has also been looking at the development and promulgation of safety promotion material for managing partial power loss situations as well as ensuring there is further guidance for pilots, instructors and examiners. This material is planned to be promulgated during Q4 2025.
