## Probable cause

THE FAILURE OF THE LEFT ENGINE TURBOCHARGERS BEARINGS, WHICH RESULTED IN A LOSS OF POWER AND SUBSEQUENT DEGRADATION OF CLIMB PERFORMANCE.

## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, takeoff - roll/run
  - 1 engine
  - exhaust system,turbocharger - worn (cause)
  - exhaust system,turbocharger - overtemperature (cause)
  - exhaust system,turbocharger - failure,partial (cause)
- In flight collision with object, takeoff - initial climb
  - object - wire,transmission
  - object - vehicle

## Analysis

DURING THE TAKEOFF GROUND RUN, WITNESSES OBSERVED THE AIRPLANE AT A SLOW SPEED, USING THE FULL LENGTH OF THE 4,102-FT RUNWAY BEFORE IT BECAME AIRBORNE BRIEFLY. THE LEFT WING DIPPED, STRUCK SOME POWER LINES, AND THE AIRPLANE CRASHED ON A HIGHWAY STRIKING A CAR. METALLURGICAL TEARDOWN EXAMINATIONS OF THE TWO LEFT ENGINE TURBOCHARGERS DISCLOSED EVIDENCE OF EXTREME WEAR IN THE BEARINGS FROM THE TURBINE WHEEL SHAFTS WHICH RESULTED IN OBSTRUCTED OIL PORTS.

## 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 19920625021769A](https://openairdocs.org/incident/19920625021769A), Jun 25, 1992: Piper PA60602P, Lancaster, PA, Destroyed. Lost power left engine on takeoff roll. Failed to abort. Catapaulted off end runway. Both turbochargers had failed.

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.
