## Probable cause

THE PILOT'S FAILURE TO MAINTAIN CLEARANCE FROM OTHER PARKED AIRCRAFT WHILE TAXIING.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- On ground/water collision with object, taxi - to takeoff
  - object - aircraft parked/standing (contributing factor)
  - visual lookout - not maintained, pilot in command (cause)
  - clearance - not maintained, pilot in command (cause)

## Analysis

WHILE TAXIING FOR TAKEOFF, A BEECH A-36 COLLIDED WITH A PARKED CESSNA 425. THE BEECH SUSTAINED SUBSTANTIAL STRUCTURAL DAMAGE TO THE LEFT WING ASSEMBLY. THE PARKED AIRCRAFT RECEIVED MINOR DAMAGE TO ITS RADOME. THE PILOT STATED THAT HE WAS ON THE YELLOW TAXI LINE AND THE CESSNA WAS ABOUT 14 FEET FORWARD OF THE NORMALLY PARKED POSITION. HOWEVER, A REVIEW OF PHOTOGRAPHS OF THE MISHAP, DISCLOSED THAT THE PILOT HAD AMPLE CLEARANCE ON THE RIGHT SIDE OF THE YELLOW LINE TO MANEUVER AROUND THE PARKED AIRPLANE AND AVOID THE COLLISION.

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.
