From the FAA registry file of October 24, 2026. ADs below are matched by the registry's airframe and engine model codes. They may apply; each AD's applicability can narrow it by serial number, part number or installed equipment. This is not a compliance determination. The registry lists only the engine series, so ADs for every Rotax 912S model are included.

## ADs that may apply (OpenAirDocs): 15 in force

## NTSB investigations

None matched to N1935C.

## NTSB investigations on N1935C not matched to an aircraft (2)

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 WPR09CA291](https://openairdocs.org/ntsb/WPR09CA291), Jun 14, 2009: Clarke Colin A Glastar (N1935C), Wenatchee, WA, substantial damage. Probable cause: The pilot’s failure to maintain adequate airspeed, resulting in an aerodynamic stall and loss of control.
- [NTSB LAX08CA176](https://openairdocs.org/ntsb/LAX08CA176), Jun 10, 2008: Clarke Colin Glastar (N1935C), Wenatchee, WA, substantial damage. Probable cause: The pilot's failure to initiate a timely go-around after the first bounce.

## FAA accident and incident reports

None matched to N1935C.

## Reports on N1935C not matched to an aircraft (2)

They name N1935C, but no registry record covers the date, the aircraft registered then was built later, or the report describes another aircraft.

## 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) (1)

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 (Rotax 912S series)

- [STC SE01966WI](https://openairdocs.org/stc/SE01966WI): Use of GAMI G100UL High Octane Unleaded Avgas in spark ignition piston aircraft engines. General Aviation Modifications Inc. Lists 912 S2

## Earlier aircraft with N1935C

The FAA can reassign an N-number once a registration is cancelled. These aircraft carried N1935C before.
