## Probable cause

FUEL STARVATION DUE THE FUEL VENT BEING BLOCKED BY A MUD DAUBER NEST AND THE PILOT'S FAILURE TO FIND THE OBSTRUCTION (INADEQUATE PREFLIGHT) BEFORE TAKING OFF.  TREES BEYOND THE DEPARTURE END OF THE RUNWAY WERE A RELATED FACTOR.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - fuel system,vent - blocked(total) (cause)
  - aircraft preflight - inadequate, pilot in command (cause)
  - fluid,fuel - starvation (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing
  - object - tree(s) (contributing factor)

## Analysis

THE PLT/OWNER OF THE NEW HOME BUILT ACFT MADE SVRL TAXI CHECKS BEFORE THE 1ST FLT.  CHECKS WERE MADE WITH THE NOSEWHEEL OFF THE RWY & A LIFT-OFF TO ABOUT 10 FT AGL.  DURING TAKEOFF, AT ABOUT 100 FT AGL, THE ENG LOST POWER. THE PLT ELECTED TO LAND ON THE OVERRUN AT THE DEP END OF THE RWY, BUT THE ENG BEGAN RUNNING AGAIN, SO HE ELECTED TO CONT THE TAKEOFF & RETURN TO THE RWY FOR LANDING.  HOWEVER, THE ENG LOST POWER AGAIN & THE PLT WAS FORCED TO LAND IN TREES BEYOND THE DEP END OF THE RWY.  A POST-ACDNT EXAM OF THE ACFT REVEALED THE FUEL VENT WAS BLOCKED BY A MUD DAUBER NEST.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19900114019969A](https://openairdocs.org/incident/19900114019969A), Jan 14, 1990: Amtr ONEDESIGN, Daytona Beach, FL, Substantial damage. Engine quit on climbout, descended into trees. Mud dauber had blocked fuel tank vent.

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.
