Aircraft involved
Probable cause & findings
THE PILOTS INTENTIONAL FLIGHT INTO ICING CONDITIONS WITH AN AIRPLANE NOT EQUIPPED FOR FLIGHT IN KNOWN ICING CONDITIONS. THIS RESULTED IN AN UNCONTROLLED DESCENT AND CONTACT WITH TREES IN INSTRUMENT METEOROLOGICAL CONDITIONS. FACTORS RELATED TO THE ACCIDENT WERE: THE PILOTS DISREGARD OF THE WEATHER BRIEFING WHICH INCLUDED FLIGHT PRECAUTIONS FOR MODERATE ICING, AND HIS OVERCONFIDENCE IN HIS ABILITY AND THE AIRPLANE'S LIMITATIONS.
Factual narrative
THE CFI RECEIVED A PRE TAKEOFF WEATHER BRIEFING WHICH INCLUDED FORECAST MODERATE ICING CONDITIONS. HE TOOK OFF WITH A STUDENT, IN AN AIRPLANE EQUIPPED WITH A HEATED PITOT TUBE, BUT NOT CERTIFIED FOR FLIGHT INTO ICING CONDITIONS. 30 MINUTES AFTER TAKEOFF THE AIRPLANE WAS UNABLE TO MAINTAIN ALTITUDE DUE TO ICE ACCUMULATIONS. THE PILOT WAS RECEIVING RADAR VECTORS TO A NEARBY AIRPORT WHEN HE DISAPPEARED FROM RADAR FOLLOWED SHORTLY BY A LOSS OF COMMUNICATIONS. IN A POST CRASH INTERVIEW, THE PILOT SAID THE LANDING GEAR EXTENDED AUTOMATICALLY AND HE WAS UNABLE TO RETRACT THEM, AND THIS CONDITION CONTRIBUTED TO HIS FAILURE TO MAINTAIN ALTITUDE. THE STUDENT PILOT ON BOARD SAID THE CFI SUCCESSFULLY RETRACTED THE LANDING GEAR AND THE AIRPLANE STILL COULD NOT MAINTAIN ALTITUDE.
