Night Flight Collides with Terrain During 180-Degree Turn in IMC (N97462)

Livermore, CA, US

On April 1, 1993, a Cessna 172P (registration N97462) operated by Business Aircraft Center, Inc was involved in an aviation accident near Livermore, CA. Investigators recorded the probable cause as: THE PILOT'S DECISION TO ATTEMPT VFR FLIGHT INTO INSTRUMENT METEOROLOGICAL CONDITIONS. FACTORS THAT CONTRIBUTED TO THIS ACCIDENT WERE: THE PILOT'S LACK OF RECENT INSTRUMENT EXPERIENCE, THE RAIN AND HIGH WIND CONDITIONS IN THE AREA. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During a night flight in instrument meteorological conditions, an airplane collided with hilly terrain in a near wings-level attitude. The pilot, instrument-rated but not current, had communicated with the tower before performing a 180-degree turn, after which no further transmissions were received. No mechanical malfunctions were found.

Accident Overview

A night flight ended when the airplane collided with hilly terrain in a near wings-level attitude. At the time of the accident, weather in the area was characterized as instrument meteorological conditions (IMC). An on-site inspection of the engine revealed no mechanical malfunctions.

Pilot Information

The pilot held an instrument rating, but a review of logbook entries indicated that he was not instrument current at the time of the accident.

Communication and Flight Path

Prior to the accident, the pilot contacted the control tower and requested a transition through their area. He subsequently advised the tower that he was going to perform a 180-degree turn. Following that transmission, no further communications were received from the pilot by the tower.

Investigation Findings

Investigators determined that the airplane struck terrain in a near wings-level attitude. The lack of mechanical issues with the engine suggests the flight was under power until impact. The pilot's lack of instrument currency may have been relevant given the IMC conditions, though the report does not explicitly state a causal relationship.
