On September 27, 1995, a Piper PA-44-180 (registration N2160E) operated by Matthias Dahlheim was involved in an aviation accident near Columbia, SC. Investigators recorded the probable cause as: the pilot's improper IFR procedure by allowing the airplane to descend below the ILS glideslope and by continued descent below the decision height. Factors relating to the accident were: darkness, low ceiling, and fog. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A multiengine airplane collided with pine trees while executing an ILS approach to runway 11 in fog and low ceiling conditions. The investigation found no preimpact failure.
Background
The flight was conducted under an instrument flight plan. The pilot and safety pilot each held instrument and multiengine ratings. Prior to departure, the pilot obtained a weather briefing and reported that they had received the local ATIS at the destination airport.
Sequence of Events
The aircraft was flying an ILS approach to runway 11. The reported weather included an overcast ceiling of 300 feet, visibility of 3 miles, and fog. While on the approach, the airplane struck a 100-foot-tall pine tree and a 150-foot-tall pine tree. After hitting the trees, the airplane crashed to the ground. The impact point was approximately half a mile from the approach end of runway 11.
Investigation Results
A post-accident examination of the wreckage was conducted. No preimpact failure of the engines, flight controls, or instruments was discovered. The investigation did not identify any mechanical or structural issues that preceded the collision.
