Lesson 9.4 – Common Accident Scenarios & Lessons Learned

(Updated with NTSB study findings)

Many general aviation accidents follow recognizable patterns. NTSB studies and accident data consistently show that a relatively small number of scenarios account for a large percentage of fatal accidents. Studying these patterns helps you recognize the same warning signs in your own flying.

Leading Accident Categories (NTSB Data)

1. Loss of Control in Flight (LOC-I)

One of the leading causes of fatal general aviation accidents. Often related to stalls, spins, spatial disorientation, or improper recovery from unusual attitudes.

Lesson: Maintain proficiency in slow flight and stall recovery, avoid conditions that lead to disorientation, and trust instruments when visual references are lost.

2. Continued VFR Flight into IMC

NTSB data shows this scenario has a very high fatality rate (historically around 70% or higher of these accidents are fatal). It frequently leads to spatial disorientation and loss of control, or to controlled flight into terrain.

Lesson: Set firm personal weather minimums and divert or turn back early. “Get-there-itis” and the invulnerability attitude are common factors.

3. Fuel Exhaustion and Fuel Starvation

A persistent cause of accidents. Most are the result of inadequate preflight planning, incorrect fuel calculations, or failure to monitor fuel in flight—not mechanical failure of the fuel system.

Lesson: Always calculate fuel required versus fuel on board (including required reserve) and monitor fuel status during the flight.

4. Controlled Flight Into Terrain (CFIT)

Occurs when a fully controlled aircraft is flown into terrain, water, or obstacles. Most common in poor visibility or at night. NTSB studies show CFIT accounts for a disproportionate share of fatalities relative to the number of accidents.

Lesson: Maintain situational awareness, use terrain awareness tools when available, and avoid scud-running.

5. Takeoff and Landing Performance Accidents

Often linked to high density altitude, overweight aircraft, short or contaminated runways, or tailwinds.

Lesson: Use the POH performance charts, calculate density altitude, and respect personal minimums for runway length and density altitude.

Common Human Factors Across These Accidents

NTSB investigations repeatedly identify:

Hazardous attitudes (especially invulnerability and macho)
External pressures (“get-there-itis”)
Failure to use personal minimums
Loss of situational awareness
Poor preflight planning or in-flight monitoring

Practical Takeaway from NTSB Studies

The majority of these accidents were preventable. The same tools you have already studied—PAVE, IMSAFE, personal minimums, structured decision making, and early action—directly address the factors that keep appearing in NTSB reports.
