Chino, CA, US

On November 10, 2002, a Beech A36 (registration N69DG) was involved in an aviation accident near Chino, CA. Investigators recorded the probable cause as: the pilot's failure to understand his IFR clearance, which resulted in a diversion of his attention during the initial climb, and his failure to maintain control of the aircraft. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot, having missed the departure frequency in the clearance, was distracted while tuning radios and struck a power line with the left wing. Post-impact fire consumed the airplane.

Accident Sequence

The airplane collided with a power line during the initial climb of an instrument departure. Prior to departure, the pilot received weather briefings that reported localized ground fog engulfing the airport of intended departure.

While holding short of the runway, the ground controller read the departure clearance to the pilot. The pilot copied and read back part of the clearance, but excluded the departure frequency. After takeoff, the pilot started a climbing left turn, and the controller directed him to contact departure. Not knowing the frequency, the pilot requested that the tower advise him of the correct frequency. The tower replied with the appropriate frequency.

The pilot glanced at his radios and noted that the active and standby frequencies were not tuned to the frequency the tower had prescribed. He reached over and input the frequency corresponding to the tower's assignment. After tuning the correct frequency, he looked back at the instrument panel and then outside the cockpit. He noticed that wires were directly in his flight path, with a building close behind them. The left wing impacted a power line, and the airplane came to rest in a pasture. A post-impact fire consumed the airplane.

Weather Conditions

The airport's weather observation facility reported that 5 minutes after the accident, the runway visual range was less than 1/4 statute miles visibility, and vertical visibility was 100 feet.
