14 Dec 2009: EADS SOCATA TBM 700 (N850MT) — TAHOE INVESTMENTS INC — Truckee, CA

Truckee, CA, United States

On 14 Dec 2009, an EADS SOCATA TBM 700 (registration N850MT) operated by TAHOE INVESTMENTS INC was involved in an aviation accident near Truckee, CA. No fatalities were reported. Investigators recorded the probable cause as: The pilot’s failure to maintain an adequate airspeed and clearance from terrain during an attempted go-around. Contributing to the accident was the pilot's decision to land on a partially obscured runway.

On December 13, 2009, a TBM-700 (N850MT) was substantially damaged after impacting terrain following an aborted landing near Truckee-Tahoe Airport. The pilot and passenger sustained minor injuries.

Location and Circumstances

On December 13, 2009, about 1738 Pacific standard time, an EADS Socata TBM-700 airplane, registered N850MT, was substantially damaged when it impacted terrain after an aborted landing near the Truckee-Tahoe Airport (TRK) in Truckee, California. The airplane was registered to Tahoe Investments, Los Altos Hills, California, and operated by the pilot under 14 CFR Part 91. The instrument-rated private pilot and his passenger received minor injuries. Instrument meteorological conditions prevailed, and an instrument flight rules (IFR) flight plan was filed for the personal cross-country flight, which originated from San Carlos Airport (SQL), San Carlos, California, at 1630 with an intended destination of TRK.

Pilot's Actions Prior to the Approach

In a written statement, the pilot reported that prior to the flight he obtained a weather briefing for the intended route and destination. He also continuously checked the TRK weather before departure. He recalled that before departure the TRK weather indicated visibility greater than 7 miles, overcast clouds at 2,000 feet, wind calm, and that runway 19 was closed. During the flight, he monitored the weather conditions at TRK and decided to conduct the Global Positioning System (GPS) Runway 19 instrument approach with the intention of circling to a different runway. The pilot reported that the passenger saw the airport as they passed over it, but he could not see it and continued IFR flight.

Approach and Go-Around

As the pilot initiated the instrument approach, he continued to monitor the weather and noted that visibility had decreased to 7 miles. He stated that during the approach he activated all of the airplane’s deicing equipment because the airplane had “picked up some light rime ice.” The pilot was unsure at what altitude the airplane broke out of the clouds because the ground was visible throughout the approach. As the airplane approached the published missed approach point (MAP), the pilot established visual contact with the runway lighting for runway 28 and subsequently canceled his IFR clearance.

Entering a left downwind for runway 28, he noticed “the first part of [runway] 28 was covered in fog.” He checked the Automated Surface Observing System (ASOS) at TRK and noted visibility was three-quarters of a mile with light snow. The pilot reported that there was at least 5,000 feet of clear runway and he decided to make a mid-field landing, just beyond the fog. Prior to touchdown, the pilot decided that there was not enough runway to land because the airplane was “too high and fast.” He initiated a go-around by applying power, pitching up, and retracting the landing gear.

Loss of Control and Impact

During the go-around, the pilot reported that he “was totally focused outside the plane because of the clouds and mountains, but had no horizon reference in the dark.” He stated that he heard an audible warning horn, which he thought was activated because he had failed to raise the landing flaps before retracting the gear. As the warning continued, the pilot observed that the airplane was not climbing; he then realized the sound was the stall warning horn. When he pitched the nose down, he immediately saw only snow and trees ahead. Unable to climb over the trees, the airplane subsequently impacted trees and terrain about 0.5 miles northwest from the departure end of runway 28.

Post-Accident Examination

Examination of the airplane by a Federal Aviation Administration (FAA) inspector revealed that the airplane came to rest upright within a wooded snow-covered field. The left and right wings were structurally damaged. The propeller assembly was separated from the engine and located adjacent to the main wreckage. A strong odor of jet fuel was also present at the accident site. The pilot reported that there were no pre-existing mechanical problems with the engine or airframe.
