## Probable cause

The nose landing gear collapse and postimpact fire due to undetermined reasons.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Not determined](https://openairdocs.org/ntsb-findings/05000000): Not determined › Not determined · Unknown/Not determined (probable cause); cases with it: [Beech C23, 5 cases](https://openairdocs.org/ntsb-findings/05000000/cases.md?model=1151242), [All aircraft, 2,247 cases](https://openairdocs.org/ntsb-findings/05000000/cases.md)

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing-flare/touchdown: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Beech C23, 6 cases](https://openairdocs.org/ntsb-events/094/sequence.md?model=1151242), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md)
- [Post-impact: Fire/smoke (post-impact)](https://openairdocs.org/ntsb-events/170); cases with it: [Beech C23, 4 cases](https://openairdocs.org/ntsb-events/170/sequence.md?model=1151242), [All aircraft, 354 cases](https://openairdocs.org/ntsb-events/170/sequence.md)

## Analysis

The pilot reported that she conducted a normal, full flap landing to the runway. After touchdown, the airplane’s nose landing gear collapsed, and a postimpact fire ensued after the airplane skidded to a stop. The airplane was destroyed by the postimpact fire which precluded a postaccident examination of the nose landing gear system. An airport surveillance video appeared to show the airplane bounce and porpoise several times before the airplane came to rest. Due to the poor quality of the surveillance video and lack of available evidence, the reason for the nose landing gear collapse and postimpact fire during landing sequence could not be determined.

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.
