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.

Pilot was practicing emergency landings and recovery when the acft struck a guy wire at the departure end of the rwy and crash landed about 100 feet from the rwy, other circumstances are unknown. (-23) in the course of practicing emergency landings the instructor allowed the student to touchdown on the grass runway with a significant tailwind and at a point that a successful go around could not be accomplished. Consequently, the airplane impacted a telephone line and trees at the departure end of the downwind runway. (.4) while simulating a loss of engine power for a third time, the airplane was landed with an approximate 10 knot tailwind, 1/2 way down the 3,000 foot grass runway with full flaps. After touchdown the student cleaned the aircraft and applied full power for the go-around without delay. During the climb out at an airspeed greater than best angle of climb (vx), the left wing of the airplane collided with an unmarked phone line about 25 feet AGL. The right wing of the airplane then collided with a tree which separated about 8-10 feet of that wing. The airplane then descended and impacted the ground coming to rest about 135 feet from the tree impact point. The CFI s tated that there was no engine, airframe, or system failure or malfunction. He also stated that he did not notice the unmarked phone line during that flight or during the previous 8-10 times he flew to that airstrip, but he did notice the trees during the climb just prior to the phone line contact. The flaps were determined to be extended approximately 5 degrees and no failure or malfunction of the flap system was noted.

As the FAA filed it

PILOT WAS PRACTICING EMERGENCY LANDINGS AND RECOVERY WHEN THE ACFT STRUCK A GUY WIRE AT THE DEPARTURE END OF THE RWY AND CRASH LANDED ABOUT 100 FEET FROM THE RWY, OTHER CIRCUMSTANCES ARE UNKNOWN. (-23) IN THE COURSE OF PRACTICING EMERGENCY LANDINGS THE INSTRUCTOR ALLOWED THE STUDENT TO TOUCHDOWN ON THE GRASS RUNWAY WITH A SIGNIFICANT TAILWIND AND AT A POINT THAT A SUCCESSFUL GO AROUND COULD NOT BE ACCOMPLISHED. CONSEQUENTLY, THE AIRPLANE IMPACTED A TELEPHONE LINE AND TREES AT THE DEPARTURE END OF THE DOWNWIND RUNWAY. (.4) WHILE SIMULATING A LOSS OF ENGINE POWER FOR A THIRD TIME, THE AIRPLANE WAS LANDED WITH AN APPROXIMATE 10 KNOT TAILWIND, 1/2 WAY DOWN THE 3,000 FOOT GRASS RUNWAY WITH FULL FLAPS. AFTER TOUCHDOWN THE STUDENT CLEANED THE AIRCRAFT AND APPLIED FULL POWER FOR THE GO-AROUND WITHOUT DELAY. DURING THE CLIMB OUT AT AN AIRSPEED GREATER THAN BEST ANGLE OF CLIMB (VX), THE LEFT WING OF THE AIRPLANE COLLIDED WITH AN UNMARKED PHONE LINE ABOUT 25 FEET AGL. THE RIGHT WING OF THE AIRPLANE THEN COLLIDED WITH A TREE WHICH SEPARATED ABOUT 8-10 FEET OF THAT WING. THE AIRPLANE THEN DESCENDED AND IMPACTED THE GROUND COMING TO REST ABOUT 135 FEET FROM THE TREE IMPACT POINT. THE CFI S TATED THAT THERE WAS NO ENGINE, AIRFRAME, OR SYSTEM FAILURE OR MALFUNCTION. HE ALSO STATED THAT HE DID NOT NOTICE THE UNMARKED PHONE LINE DURING THAT FLIGHT OR DURING THE PREVIOUS 8-10 TIMES HE FLEW TO THAT AIRSTRIP, BUT HE DID NOTICE THE TREES DURING THE CLIMB JUST PRIOR TO THE PHONE LINE CONTACT. THE FLAPS WERE DETERMINED TO BE EXTENDED APPROXIMATELY 5 DEGREES AND NO FAILURE OR MALFUNCTION OF THE FLAP SYSTEM WAS NOTED.
