From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Operating in IMC VFR struck mountainside climbing to cruise. (.4) while flight following, the pilot was advised by the controller that he was cleared for 'unrestricted descent' and was given the current altimeter setting. After the transmission, the pilot acknowledged that there were clouds in his vicinity but began a descent toward the destination airport with the gear extended. The aircraft collided with utility lines located on a ridge that crossed the pilot's route of flight. After the aircraft descended below the base of radar coverage, the controller advised that radar contact was lost; however, the pilot did not respond. Further attempts to contact the pilot were unsuccessful. The aircraft was equipped with navigational radios that were compatible with the published approach at the destination, and reported weather was above published minimums; however, the instrument rated pilot did not request a clearance nor were instrument charts found at the accident site. Visibility at the accident site was reported about 100 to 200 feet in mist with heavy precipitation and clouds at tree top level.

As the FAA filed it

OPERATING IN IMC VFR STRUCK MOUNTAINSIDE CLIMBING TO CRUISE. (.4) WHILE FLIGHT FOLLOWING, THE PILOT WAS ADVISED BY THE CONTROLLER THAT HE WAS CLEARED FOR 'UNRESTRICTED DESCENT' AND WAS GIVEN THE CURRENT ALTIMETER SETTING. AFTER THE TRANSMISSION, THE PILOT ACKNOWLEDGED THAT THERE WERE CLOUDS IN HIS VICINITY BUT BEGAN A DESCENT TOWARD THE DESTINATION AIRPORT WITH THE GEAR EXTENDED. THE AIRCRAFT COLLIDED WITH UTILITY LINES LOCATED ON A RIDGE THAT CROSSED THE PILOT'S ROUTE OF FLIGHT. AFTER THE AIRCRAFT DESCENDED BELOW THE BASE OF RADAR COVERAGE, THE CONTROLLER ADVISED THAT RADAR CONTACT WAS LOST; HOWEVER, THE PILOT DID NOT RESPOND. FURTHER ATTEMPTS TO CONTACT THE PILOT WERE UNSUCCESSFUL. THE AIRCRAFT WAS EQUIPPED WITH NAVIGATIONAL RADIOS THAT WERE COMPATIBLE WITH THE PUBLISHED APPROACH AT THE DESTINATION, AND REPORTED WEATHER WAS ABOVE PUBLISHED MINIMUMS; HOWEVER, THE INSTRUMENT RATED PILOT DID NOT REQUEST A CLEARANCE NOR WERE INSTRUMENT CHARTS FOUND AT THE ACCIDENT SITE. VISIBILITY AT THE ACCIDENT SITE WAS REPORTED ABOUT 100 TO 200 FEET IN MIST WITH HEAVY PRECIPITATION AND CLOUDS AT TREE TOP LEVEL.
