## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(partial) - mech failure/malf, approach - vfr pattern - final approach
  - ignition system,magneto - incorrect (cause)
  - throttle/power control - delayed, pilot in command (contributing factor)
  - maintenance,adjustment - improper, other maintenance personnel (cause)
- Undershoot, landing - flare/touchdown
  - planned approach - poor, pilot in command (cause)

## Analysis

THE ACFT WAS LANDED 200 FT SHORT OF THE RWY IN BUSHES AFTER THE ENGINE HESITATED DURING THE PLTS APPLICATION OF THROTTLE IN AN ATTEMPT TO REACH THE RWY. AN FAA INSPECTOR FOUND THE MAGNETO TIMING SET TO 23 PLUS DEGREES RATHER THAN THE PRESCRIBED 20 DEGREES.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19840513016899A](https://openairdocs.org/incident/19840513016899A), May 13, 1984: Tcrafk F21, Payson, AZ, Substantial damage. Engine failed to respond on low final for landing at a dirt strip. Struck trees. Magneto timing caused power delay.

## Other investigations on N2005U (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB LAX03LA071](https://openairdocs.org/ntsb/LAX03LA071), Jan 18, 2003: Taylorcraft F21 (N2005U), Payson, AZ, substantial damage. Probable cause: failure of the pilot to maintain directional control of the airplane during landing.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
