## Probable cause

The pilot’s failure to maintain an adequate visual lookout during taxi, which resulted in a collision with a parked airplane. Contributing was the marshaller’s improper marshalling techniques.

## Findings

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

## Sequence of events

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

- [Taxi-from runway: Ground collision](https://openairdocs.org/ntsb-events/200) (defining event); cases with it: [Cessna 180, 2 cases](https://openairdocs.org/ntsb-events/200/sequence.md?model=2072602), [All aircraft, 618 cases](https://openairdocs.org/ntsb-events/200/sequence.md)

## Analysis

Shortly after landing, while taxing to get fuel, the pilot was being guided by a marshaller who was not using correct hand signaling techniques and appeared to wave at the pilot in a “follow me” fashion. As the pilot continued to taxi straight ahead, the marshaller stopped giving hand signals and watched the pilot continuing to taxi straight ahead before executing a sharp right turn directly into a parked airplane. During the turn, the taxiing airplane’s left wing impacted the parked airplane’s left propeller resulting in substantial damage to the taxiing airplane and minor damage to the parked airplane. The taxiing pilot reported she did not see the other airplane because her attention was focused on the marshaller.
