Analysis

The pilot of the tundra-tire, tailwheel-equipped airplane reported that, while landing off airport on a gravel bar, he "got on the brakes a little too hard and the tail came up and the airplane flipped over."

The airplane sustained substantial damage to the left wing lift strut.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's overapplication of the brakes during landing, which resulted in a nose-over.

Analysis 

The solo student pilot reported that, during landing, about 10 ft above ground, the glider was "hit by a tail gust/downdraft," then it landed hard.

The glider sustained substantial damage to the fuselage.

Analysis 

The pilot of the float-equipped airplane reported that, during a flight at dusk with high, gray overcast clouds, he circled over a lake and began the approach to land. He added that his depth perception was off, he misjudged the approach, and the airplane struck a tree.

The airplane sustained substantial damage to both wings.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated weather observation station located about 6 miles northwest of the accident site reported that, about 23 minutes after the accident, the wind was calm, scattered clouds at 4,100 ft, and overcast clouds at 6,000 ft. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be: 
The pilot's failure to maintain a proper approach path during landing in dusky, flat light conditions, which resulted in a tree strike. 

Findings

Aircraft
Descent/approach/glide path - Not attained/maintained (Cause)

Analysis 

During the second wheel landing of the flight and shortly after the tailwheel touched down on the runway, the airplane drifted right. The commercial pilot attempted to stop the drift by applying the wheel brakes. Subsequently, the airplane nosed over. The right wing, rudder, and vertical stabilizer sustained substantial damage. During a postaccident interview, the pilot stated that he "got on [the] brakes a little harder than I should have."

Examination of the landing gear assembly and rudder control linkages did not reveal any evidence of preimpact mechanical malfunctions or failures that would have precluded normal operation. Therefore, it is likely the pilot's overapplication of the brakes resulted in the nose-over.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's overapplication of the wheel brakes during landing, which resulted in a nose-over.

Findings

Aircraft
Brake - Incorrect use/operation (Cause)

Personnel issues
Aircraft control - Pilot (Cause)
Use of equip/system - Pilot (Cause)

Factual Information 

On June 25, 2018, about 1145 eastern daylight time, a Stearman B75N1, N52584, was substantially damaged when it nosed over during landing at Davidson County Airport (EXX), Lexington, North Carolina. The airline transport pilot sustained minor injuries and the passenger was not injured. The airplane was operated by the pilot as a personal flight conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and no flight plan was filed for the local flight.

According to the pilot, during the second wheel landing of the flight, shortly after the tailwheel touched down on runway 24, the airplane drifted to the right. He attempted to stop the drift, and as the airplane approached the right edge of the runway, he applied the wheel brakes. Subsequently, the airplane nosed over on the runway. The right wing, rudder, and vertical stabilizer sustained substantial damage. During a postaccident interview, the pilot stated he "got on [the] brakes a little harder than I should have" as the airplane drifted toward the grass.

According to a witness who was at the airport in the ramp area, he heard "a faint sound of screeching tires." As he looked up, he observed the airplane "pitch nose forward" and nose over on the runway.

During postaccident examinations by a Federal Aviation Administration (FAA) inspector, while the airplane was at the accident site inverted, the main landing gear wheels and tailwheels rotated freely when moved by hand. The tailwheel was found locked, which was consistent with its control lever in the cockpit. The tailwheel locking mechanism functioned normally when the lever was moved to the unlock and lock positions. The push-pull control linkages were examined from the rudder pedals to the tailwheel and rudder surface, and no anomalies were noted.

According to FAA airman records, the pilot held an airline transport pilot certificate with a rating for airplane multi-engine land. He also held a commercial pilot certificate with ratings for airplane single-engine land, helicopter, and instrument helicopter. His most recent first-class medical certificate was issued in March 2018. He reported that he had accumulated 30,000 total flight hours, and 350 total flight hours in the accident make and model airplane.

According to FAA airworthiness records, the two-seat, single-engine, bi-wing, tailwheel airplane was manufactured in 1941. It was equipped with a Lycoming R-680-13 engine. The most recent annual inspection was completed in October 2017.

The weather conditions reported at 1155 at EXX, included calm wind, visibility 10 statute miles, clear skies, temperature 29°C, and dew point 21°C.

Analysis 

The powered-glider pilot reported that, during the return flight to the airport after an informal glider competition, about 10,000 to 11,000 ft over mountainous terrain, he was unable to find lift, the glider descended to 9,000 ft, and he started the sustainer engine. He added that, after the glider climbed back to the initial altitude, he shut the sustainer engine off, stowed it, and continued to the destination airport.

He reported that, about 4 miles from the airport, the glider began to sink about 1,000 ft per minute. He attempted to restart the engine but was unsuccessful in the limited time available. He chose a field for an off-airport landing, the glider touched down, but the ground was slightly uneven, which resulted in the right wing dragging. The glider veered 20° to the right before coming to rest.

The glider sustained substantial damage to the horizontal stabilizer and elevator.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.

An automated weather observation station at an elevation of 7,950 ft, located about 14 miles east-southeast of the accident location, reported wind from 270° at 10 knots, gusting to 15 knots; temperature 79°F; and dew point 9F. The calculated density altitude was 10,300 ft.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's inability to maintain altitude and his delayed decision to deploy the powered-glider's engine, which necessitated an off-airport landing.

Findings

Altitude - Attain/maintain not possible (Cause)

Analysis 

According to the glider pilot, about 15 minutes into the flight, the glider had reached 2,000 ft above ground level (agl), but he was unable to find more lift. The glider was about 1.5 miles west of the airfield, and he decided to continue west in search of lift under a cloud formation. He did not find lift and returned to his previous position 1.5 miles west of the airfield at 1,200 ft agl. The pilot decided to land off the airfield.

The pilot entered the pattern using the glider's spoilers and turned from the downwind leg to the base leg at 700 ft agl. He reported that he allowed the glider's flightpath to take him .5 mile too far downwind. During the base leg of the pattern, he reported that he had to "crab the airplane into the wind" to avoid being pushed further downwind. On final, the glider descended rapidly and collided with trees.

The glider sustained substantial damage to the left wing spar.
