## Information bulletins (advisory)

None matched.

## NTSB investigations (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 CEN13LA366](https://openairdocs.org/ntsb/CEN13LA366), Jun 18, 2013: Israel Aircraft Industries 1124 (N112EM), Cincinnati, OH, substantial damage. Probable cause: Loss of control due to insufficient airspeed on takeoff and premature landing gear retraction, which resulted in the collapse of the left landing gear as the airplane impacted the runway.

## FAA accident and incident reports (1)

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

## 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) (110, first 50)

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.
