A pilot departed late afternoon without a weather briefing or flight plan, entering IMC under a ragged ceiling and striking trees on a ridge.

What happened

During an early morning predeparture weather briefing, the pilot was advised that deteriorating weather conditions were expected later in the day. Despite this warning, the pilot proceeded with a cross-country flight to conduct business. The pilot departed late in the afternoon without obtaining a current weather briefing or filing a flight plan.

Both the departure area and the destination airport reported Instrument Meteorological Conditions (IMC) at the time of departure. While attempting to remain under Visual Flight Rules (VFR) beneath a ragged ceiling of approximately 600 feet, the pilot inadvertently entered clouds. The aircraft subsequently struck trees on a ridge.

The investigation

The investigation focused on the sequence of events leading up to the impact and the environmental conditions present during the flight. Investigators examined the weather reports available at the time of departure and the pilot's decision-making process regarding the lack of a flight plan and updated briefing.

Findings

Contributing factors included the pilot's failure to obtain a current weather briefing prior to departure and the decision to operate in deteriorating conditions. The aircraft was operated below the minimum safe altitude for the terrain, resulting in controlled flight into terrain (CFIT).

The pilot entered clouds while attempting to remain VFR under a ragged 600 ft ceiling.

Safety message

Pilots are reminded that weather conditions can change rapidly. It is critical to obtain a current weather briefing immediately prior to departure and to file a flight plan. Operating in IMC without proper instrumentation or training poses a significant risk of controlled flight into terrain.

Probable cause

The pilot's failure to maintain visual reference while flying in deteriorating weather conditions, which resulted in the aircraft striking trees on a ridge.
