Attention:
- Research a case study
- Discuss how the initial conditions developed into an incident/accident/mishap
- Relate similar personal experience of the same type of incident/accident/mishap
Motivator:
- Practicing spins build awareness regarding the recognition of, entry into, and recovery from spins
- An aggravated stall resulting in auto-rotation about the spin axis wherein the aircraft follows a corkscrew path due to one wing being more stalled than another
- Characterized by high AoA, low airspeed, and high rate of descent where all aerodynamic and inertial forces are balanced
- It is this balance that must be upset to recover
- Spins can be entered from any flight attitude and from practically any airspeed
- A spin is initiated where the pilot includes or fails to include rudder, aileron, or power individually or in combination during a stall
- Auto-rotation occurs from an asymmetrical stall (think skid)
- There is an abrupt loss of control when leaving the stall and entering the spin
- Certification standards require the practice of spin procedures
- Ensure to follow appropriate regulations related to spins throughout the conduct of the maneuver

Spin Awareness Guided Scenario(s):
- While turning base to final, the pilot notices they're about to overshoot the runway.
- Should the pilot just overshoot final toward the other side of the airport?
- Should the pilot increase the angle of bank and get back on final to avoid potentially flying into other aircraft's flight paths?
- Are there any other actions the pilot should or should not perform?
- Related scenarios:
- None
- Aids: None

Spin Case Studies:
- NTSB Identification: ERA14FA345 The National Transportation Safety Board determines the probable cause(s) of this accident to be:
- The pilot's failure to maintain adequate airspeed for the airplane's configuration and flight profile, which resulted in an exceedance of the wing's critical angle-of-attack and a subsequent aerodynamic stall/spin
- NTSB Identification: ERA14FA345 The National Transportation Safety Board determines the probable cause(s) of this accident to be:
