Failure modes

Accident topics

Every fatal accident in our dataset is classified into one primary failure mode. Study a category to see the pattern repeat — and how to break it.

753

Loss of Control in Flight

In-flight loss of aircraft control from a variety of causes — the single largest category of fatal GA accidents.

498

VFR into IMC

Visual-rules flights that pressed on into instrument conditions — the deadliest decision in general aviation, and one that experience does not reliably prevent.

378

Undetermined

Accidents where the cause could not be established — often because the aircraft or occupants were never recovered.

333

Mechanical & Engine Failure

Powerplant failures, part separations, and system malfunctions — and the choices pilots make in the seconds that follow.

326

Low-Altitude Maneuvering

Buzzing, canyon flying, and aggressive low passes that leave no margin when something goes wrong.

295

Fuel Exhaustion & Starvation

Running tanks dry, or failing to feed usable fuel to a running engine — almost entirely preventable with planning and fuel discipline.

269

Takeoff & Initial Climb

Accidents in the high-workload moments just after liftoff, when altitude and options are scarce.

204

Stall / Spin

Exceeding the wing's critical angle of attack at low altitude — most lethal in the turn from base to final, where there is no room to recover.

150

Controlled Flight Into Terrain

A working airplane flown into terrain or obstacles, often in reduced visibility, darkness, or rising ground the pilot never saw.

Weather (Other)

Wind, turbulence, icing, and other weather factors beyond VFR-into-IMC.

Landing / Ground Loss of Control

Runway excursions, hard landings, and ground loops — usually survivable, occasionally not.

Midair Collision

Two aircraft occupying the same airspace — see-and-avoid's hardest failures.
