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.

The pilot in command stated he was instructing a student on mild crosswind landings on runway 24 at Roanoke airport. The instructor had flown with this student once before, previously instructing him on landings in the pattern.

The student and instructor completed the first lap in the pattern and performed a go around as instructed by the instructor. The first lap in the pattern and go around was uneventful.

On the second lap in the pattern, the student performed a stabilized approach, crabbed into the wind as normal (light right crosswind), applying left rudder to straighten the nose to maintain runway centerline on runway 24. When the aircraft was over the landing area, the student continued to press on the left rudder which caused the aircraft to continue to turn left, offsetting the aircraft from the runway centerline. Before the wheels touched, the student continued to add left rudder pulling the nose further to the left. The instructor ordered a go around, but at that point, the aircraft was too low to the ground and the instructor and student had already lost control of the aircraft after the wheels touched the ground. The wheels impacted the runway causing a hard landing, bouncing the aircraft towards the left. The aircraft banked sharply to the left causing the left wing to drop low to the ground. The aircraft then banked to the right causing the right wing to drop impacting the grass area between the runway and taxiway. This caused the aircraft's nose to drop and impact the grass surface. The aircraft spun 360 degrees on the surface causing even more damage. The aircraft ultimately sustained substantial damage.

As the FAA filed it

THE PILOT IN COMMAND STATED HE WAS INSTRUCTING A STUDENT ON MILD CROSSWIND LANDINGS ON RUNWAY 24 AT ROANOKE AIRPORT. THE INSTRUCTOR HAD FLOWN WITH THIS STUDENT ONCE BEFORE, PREVIOUSLY INSTRUCTING HIM ON LANDINGS IN THE PATTERN.

THE STUDENT AND INSTRUCTOR COMPLETED THE FIRST LAP IN THE PATTERN AND PERFORMED A GO AROUND AS INSTRUCTED BY THE INSTRUCTOR. THE FIRST LAP IN THE PATTERN AND GO AROUND WAS UNEVENTFUL.

ON THE SECOND LAP IN THE PATTERN, THE STUDENT PERFORMED A STABILIZED APPROACH, CRABBED INTO THE WIND AS NORMAL (LIGHT RIGHT CROSSWIND), APPLYING LEFT RUDDER TO STRAIGHTEN THE NOSE TO MAINTAIN RUNWAY CENTERLINE ON RUNWAY 24. WHEN THE AIRCRAFT WAS OVER THE LANDING AREA, THE STUDENT CONTINUED TO PRESS ON THE LEFT RUDDER WHICH CAUSED THE AIRCRAFT TO CONTINUE TO TURN LEFT, OFFSETTING THE AIRCRAFT FROM THE RUNWAY CENTERLINE. BEFORE THE WHEELS TOUCHED, THE STUDENT CONTINUED TO ADD LEFT RUDDER PULLING THE NOSE FURTHER TO THE LEFT. THE INSTRUCTOR ORDERED A GO AROUND, BUT AT THAT POINT, THE AIRCRAFT WAS TOO LOW TO THE GROUND AND THE INSTRUCTOR AND STUDENT HAD ALREADY LOST CONTROL OF THE AIRCRAFT AFTER THE WHEELS TOUCHED THE GROUND. THE WHEELS IMPACTED THE RUNWAY CAUSING A HARD LANDING, BOUNCING THE AIRCRAFT TOWARDS THE LEFT. THE AIRCRAFT BANKED SHARPLY TO THE LEFT CAUSING THE LEFT WING TO DROP LOW TO THE GROUND. THE AIRCRAFT THEN BANKED TO THE RIGHT CAUSING THE RIGHT WING TO DROP IMPACTING THE GRASS AREA BETWEEN THE RUNWAY AND TAXIWAY. THIS CAUSED THE AIRCRAFT'S NOSE TO DROP AND IMPACT THE GRASS SURFACE. THE AIRCRAFT SPUN 360 DEGREES ON THE SURFACE CAUSING EVEN MORE DAMAGE. THE AIRCRAFT ULTIMATELY SUSTAINED SUBSTANTIAL DAMAGE.
