## Sequence of events

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

## Analysis

THE ACFT LOST POWER DURING TAKEOFF CLIMB AND CRASHED ON THE ARPT DURING A FORCED LANDING. EXAMINATION OF THE ACFT AFTER THE ACCIDENT REVEALED THAT THE RIGHT FUEL TANK VENT WAS CLOGGED ABOUT 4 INCHES INTO THE VENT BY A MUD DAUBER NEST RESTRICTING FUEL FLOW TO THE ENGINE.

## Other investigations on N20BS (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.
