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 CFM International CFM56-7B20 model are included.

## NTSB investigations

None matched to N737KA.

## NTSB investigations on N737KA 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 ANC93LA023](https://openairdocs.org/ntsb/ANC93LA023), Dec 24, 1992: De Havilland DHC2 (N737KA), Two Moon Bay, AK, substantial damage. Probable cause: AN INADVERTANT LANDING GEAR EXTENSION AND WHEELS DOWN WATER LANDING BY THE PILOT IN COMMAND. A FACTOR RELATING TO THE ACCIDENT WAS THE LACK OF CHECKLIST USE BY THE PILOT.

## FAA accident and incident reports

None matched to N737KA.

## Reports on N737KA not matched to an aircraft (1)

They name N737KA, but no registry record covers the date, the aircraft registered then was built later, or the report describes another aircraft.
