## Sequence of events

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

- Airframe/component/system failure/malfunction, landing - roll
  - landing gear,normal brake system - inoperative (contributing factor)
- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)

## Analysis

DURING THE TAKE-OFF ROLL FOR AN AERIAL APPLICATION OPERATION, THE PILOT SAID HE LOST HIS LEFT WHEEL BRAKING CAPABILITY. HE CONTINUED THE TAKE-OFF, FLEW TO THE FARM FIELD TO BE TREATED, APPLIED THE LOAD, THEN RETURNED TO A NEAR BY ALTERNATE LANDING STRIP BECAUSE OF A LONGER RUNWAY AND FACILITIES. DURING THE LANDING ROLL, DIRECTIONAL CONTROL WAS LOST. THE ACFT VEERED TO THE RIGHT, RAN OFF THE RUNWAY AND STRUCK A DITCH.

## 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 19880723027699A](https://openairdocs.org/incident/19880723027699A), Jul 23, 1988: Ayres S2RRESTD, Brinkley, AR, Substantial damage. Tried to land without the left brake that failed on takeoff. Veered off runway into a ditch.

## Other investigations on N4080X (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 FTW94LA164](https://openairdocs.org/ntsb/FTW94LA164), May 17, 1994: Aero Commander S2R (N4080X), Monticello, AR, substantial damage. Probable cause: THE LOSS OF ENGINE POWER DUE TO THE NUMBER 2 CYLINDER CRACKING. A FACTOR WAS THE LACK OF SUITABLE TERRAIN FOR THE FORCED 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.
