## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with inflight powerplant failure and restart procedures, if applicable, in a multiengine airplane.

## Knowledge elements

- **AA.VII.D.K1** — Flight characteristics and controllability associated with maneuvering the airplane with powerplant(s) inoperative, including the importance of drag reduction.
- **AA.VII.D.K2** — Powerplant restart procedures and conditions where a restart attempt is appropriate.

## Risk management elements

- **AA.VII.D.R1** — Powerplant(s) failure.
- **AA.VII.D.R2** — Methods for handling a powerplant failure or a powerplant restart.
- **AA.VII.D.R3** — Diagnosis of the cause of the powerplant failure.
- **AA.VII.D.R4** — Collision hazards.
- **AA.VII.D.R5** — Configuring the airplane.
- **AA.VII.D.R6** — Factors and situations that could lead to an inadvertent stall, spin, and loss of control with an inflight powerplant failure.
- **AA.VII.D.R7** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **AA.VII.D.S1** — Recognize and correctly identify powerplant(s) failure, complete memory items (if applicable), and maintain positive airplane control.
- **AA.VII.D.S2** — Coordinate with crew, if applicable, and complete the appropriate emergency procedures and checklist(s) for propeller feathering or powerplant shutdown.
- **AA.VII.D.S3** — Use flight controls in the proper combination as recommended by the manufacturer, or as required to maintain best performance, and trim as required.
- **AA.VII.D.S4** — Determine the cause for the powerplant(s) failure and if a restart is a viable option.
- **AA.VII.D.S5** — Maintain the operating powerplant(s) within acceptable operating limits.
- **AA.VII.D.S6** — Maintain airspeed ±10 knots, altitude ±100 feet, headings ±10°, as specified by the evaluator and within the airplane’s capability.
- **AA.VII.D.S7** — Consider a powerplant restart and, if appropriate, demonstrate the powerplant restart procedures in accordance with the manufacturer or operator specified procedures and checklists.
- **AA.VII.D.S8** — Select the nearest suitable airport or landing area.
- **AA.VII.D.S9** — Communicate with air traffic control (ATC) and the evaluator, as appropriate for the situation.

## Difficulty methodology

Difficulty calibration is ongoing for this Task. Observed difficulty is a privacy-thresholded check-ride.ai mock-oral practice proxy, not an FAA practical-test pass or fail rate. Underlying sample sizes and the private reporting threshold are not published.

## Official Task notes

- See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.

## Use in practice

A mock examiner can ask a pilot to explain the published elements, apply them to the configured aircraft and airport context, identify risks, and defend a decision. Practice prompts are not represented as actual FAA examiner scripts or predictions of the questions a candidate will receive.
