## Probable cause

A LOSS OF ENGINE POWER AND SUBSEQUENT FORCED LANDING WHICH RESULTED FROM BINDING OF THE CARBUERATOR THROTTLE SHAFT. THE BINDING RESULTED FROM AN IMPROPER OVERHAUL OF THE CARBUERTOR APPROXIMATELY 10 FLIGHT HOURS PRIOR TO THE ACCIDENT.

## Sequence of events

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

- Airframe/component/system failure/malfunction, approach - vfr pattern - base leg/base to final
  - fuel system,carburetor - jammed (cause)
  - fuel system - restricted
  - maintenance,overhaul - improper, other maintenance personnel (cause)
- Forced landing, approach - vfr pattern - base leg/base to final
- In flight collision with terrain/water, landing - flare/touchdown
  - object - vehicle

## Analysis

THE PILOT OF THE PIPER PA-28, WAS ON A 2 MILE RIGHT BASE LEG TO RUNWAY 24 AT HYANNIS AIRPORT, MA, AND HAD JUST REDUCED POWER WHEN THE THROTTLE GOT STUCK IN THE CLOSED POSITION. THE PILOT FELT THAT HE COULD NOT MAKE IT TO THE AIRPORT, SO HE ATTEMPTED A LANDING ON A HIGHWAY. AS THE AIRCRAFT WAS ABOUT TO TOUCH DOWN ON THE HIGHWAY THE LANDING GEAR HIT A CAR, KILLING A PASSENGER RIDING IN THE CAR. EXAM OF THE ENGINE REVEALED THAT THE THROTTLE SHAFT HAD SEIZED WITH THE THROTTLE PLATE IN THE CLOSED POSITION. EXAM OF SHAFT SCRATCHING AND GALLING AT THE BUSHING. TESTING OF THE BUSHING AND SHAFT REVEALED BOTH WERE MANUFACTURED OF THE SAME MATERIAL AND WERE BELOW THE HARDNESS SPECIFICATION OF THE CARBURETOR MANUFACTURER. THE CARBURETOR HAD BEEN MANUFACTURED APPROXIMATELY 10 FLIGHT HOURS PRIOR TO THE ACCIDENT.
