Risk Management Elements on the A&P Oral: What the "R" Codes Ask

October 26, 2026 · Primary sources checked October 26, 2026

The “R” codes in the Aviation Mechanic General, Airframe, and Powerplant Airman Certification Standards (ACS) identify risk management elements for airframe and powerplant (A&P) applicants. For ACS risk management elements, A&P oral and practical (O&P) preparation should include explaining the hazard and its control; our advice does not mean each R code receives a separate standalone oral question.

K, R and S in the ACS framework

The Federal Aviation Administration (FAA) divides subjects into knowledge (K), risk management (R), and skill (S) elements. Each ACS subject introduces its lists with fixed wording: knowledge, “The applicant demonstrates understanding of:”; risk management, “The applicant demonstrates the ability to identify, assess, and mitigate risks associated with:”; skills, “The applicant demonstrates the ability to:”. Our reading: naming a hazard is a starting point. Explain how the situation could affect the work, then identify the applicable precaution and the reference you would use. A memorized code label alone does not describe your decision.

Where R elements fit in the O&P

The ACS explicitly states: “Knowledge and risk management elements are also evaluated during the knowledge testing phase”. For the standalone oral, Appendix 1 describes questions drawn from knowledge elements. For selected practical projects, the ACS says the Mechanic Test Generator (MTG) includes questions on knowledge and risk management elements. The ACS says those project-specific questions “should be asked, in context, during the practical demonstration portion of the test.”

R elements can also appear among oral questions: the FAA sample oral and practical test, marked for practice purposes only, includes an oral question coded AM.I.F.R7 in its General section. Our reading: the passages above do not set a separate oral question for every R element or an R-question quota. Treat explaining risk aloud as preparation for both the oral and the practical, rather than a prediction about your oral planning sheet.

Six exact R elements across General, Airframe and Powerplant

• AM.I.B.R1 — “Interpretation of plus or minus tolerances as depicted on aircraft drawings.”
• AM.I.B.R4 — “Identification of the current version and applicability of drawing being used.”
• AM.II.E.R3 — “High pressure fluids and gases.”
• AM.II.E.R6 — “Operation of retractable landing gear systems around personnel.”
• AM.III.A.R1 — “Maintenance that requires moving the propeller.”
• AM.III.I.R3 — “Handling of fuel metering system components that may contain fuel.”

Our study prompts: for a drawing, explain how you would establish applicability before using a tolerance; for a pressure system, name the hazard before discussing a task; for gear, propeller, or fuel work, identify the people and equipment that could be affected. Those prompts are not maintenance instructions. Obtain the actual precautions from applicable current maintenance information and instruction.

Build a risk answer around the assigned situation

Our suggested answer structure has three parts: identify the specific hazard, explain the consequence relevant to the task, and describe how the applicable procedure controls the risk. If you cannot establish the precaution, say which reference you need before proceeding. Avoid substituting a generic “be careful” for a task-specific explanation.

The ACS safety appendix says the evaluator ensures the applicant follows all safety recommendations and precautions while performing the assigned projects, including use of current maintenance and overhaul publications and procedures. The safety appendix includes observing precautions such as safety glasses, hearing protection, and any other required personal protective equipment (PPE); the listed items are examples. The ACS states that any disregard for safety is not tolerated and will result in a failure.

If a project requires an action that would jeopardize safety, the evaluator will ask the applicant to simulate that portion. Our advice for rehearsal: discuss the boundary with your instructor before working, rather than improvising a hazardous demonstration. A spoken account of a control is preparation; it does not authorize performing the maintenance.

Before the oral

For the separate oral count, the MTG FAQ specifies one question for each distinct missed ACS code plus at least four random questions per applicable section. Our practice suggestion: for any R code on your AKTR, describe the hazard and its control aloud, and take the actual precautions from the applicable current maintenance information.
