## Information bulletins (advisory)

None matched.

## NTSB investigations

None matched to N12GX.

## NTSB investigations on N12GX not matched to an aircraft (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 CEN22LA061](https://openairdocs.org/ntsb/CEN22LA061), Dec 1, 2021: Experimental Nieuport-12 (N12GX), Midland, TX, substantial damage. Probable cause: The pilot’s loss of directional control during a high-speed taxi operation and subsequent collision with terrain during the inadvertent flight.

## FAA accident and incident reports

None matched to N12GX.

## Reports on N12GX not matched to an aircraft (1)

They name N12GX, but no registry record covers the date, the aircraft registered then was built later, or the report describes another aircraft.

On December 1, 2021, at approximately 1540 CDT, a Lee g r robertson 7/8TH nieuport-12 aircraft bearing registration number N12GX crashed. The aircraft was…

## Service difficulty reports

None filed for this aircraft. Matched to this aircraft by N-number and event date, checked against the reported serial number, make and model.

## STCs that may be installed (OpenAirDocs) (2)

Approved for this aircraft's airframe or engine model, in force first, then newest. The registry doesn't record which STCs an aircraft has; its records do.

### Approved for the engine (Honeywell TFE731-3)

- [STC SE00648CH](https://openairdocs.org/stc/SE00648CH): Convert AlliedSignal TFE731-3-1E/F/K engines to TFE731-3-2AP engines. International turbine Industries

## Earlier aircraft with N12GX

The FAA can reassign an N-number once a registration is cancelled. These aircraft carried N12GX before.

- [Cancelled 2018-03-09](https://openairdocs.org/deregistered/N12GX-2018-03-09): Lee G R/Robertson R A 7/8 NIEUPORT-12, S/N 001, built 1987. Registration expired, pending cancellation.
