## Registered aircraft

None registered with this engine model now.

## NTSB investigations (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 LAX01IA073](https://openairdocs.org/ntsb/LAX01IA073), Jan 6, 2001: Boeing 747-200F (N470EV), Honolulu, HI, incident, no damage. Probable cause: the failure of the lighting dimmer switch or circuit components for undetermined reasons, which resulted in smoke in the cockpit.
- [NTSB LAX96IA199](https://openairdocs.org/ntsb/LAX96IA199), May 19, 1996: Boeing 747-273C (N470EV), Los Angeles, CA, incident, minor damage. Probable cause: the operator's failure to adopt a manufacturer's stipulated ultrasonic inspection procedure, which led to the in-flight separation of the wing panel.

## FAA accident and incident reports (3)

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.
