3. Downloaded from www.avhf.com Common Scenario Accident occurred during a flight review Conditions were day, VFR with winds nearby reported at about 5 knots No anomalies were found with flight or power controls, or with the engine Last moments reconstructed using radar data and data recovered from the aircraft’s PFD and MFD

6. Downloaded from www.avhf.com Yaw and stall must both be present in order for an aircraft to spin. —What are the various sources of yaw? Discussion

11. Downloaded from www.avhf.com Unless the manufacturer states otherwise, how should spin recovery inputs be applied? Discussion

12. Downloaded from www.avhf.com Discussion Step 1—REDUCE THE POWER (THROTTLE) TO IDLE. Power aggravates the spin characteristics. Step 2—POSITION THE AILERONS TO NEUTRAL. Ailerons may have an adverse effect on spin recovery. Step 3—APPLY FULL OPPOSITE RUDDER AGAINST THE ROTATION. Make sure that full (against the stop) opposite rudder has been applied. Step 4—APPLY A POSITIVE AND BRISK, STRAIGHT FORWARD MOVEMENT OF THE ELEVATOR CONTROL FORWARD OF THE NEUTRAL TO BREAK THE STALL. This should be done immediately after full rudder application. Step 5—AFTER SPIN ROTATION STOPS, NEUTRALIZE THE RUDDER. Source: Airplane Flying Handbook, Pg. 4-15
