Flight Score
Departure
Roll the wings level with aileron and hold bank within limits as you establish the climb.
What happened: Bank increased to 1.4° during the initial climb, and wings stayed over-banked at 10° into the next climb segment.
Watch for: Attitude indicator bank angle, aiming to keep it near wings-level
Arrival
Reduce power earlier on final so threshold speed settles at 66 kt instead of carrying it into the flare.
What happened: You crossed the threshold at 117 kt, well above the 66 kt target speed, and that excess speed was still showing at touchdown. Crossing the threshold fast usually carries straight through to a fast touchdown.
Watch for: Airspeed indicator against 66 kt on short final.
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: seven checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
The approach, gate by gate
Side view — the last 1,682 m of the approach.
Plan view — the first 1,682 m of the 2,740 m runway, to the same scale as the side view.
Touched down 1,226 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
This aircraft flight began with a brief taxiing period from the parking area to the runway at KFHR Friday Harbor Airport, covering less than 1 nm in under a minute. The departure roll started from runway 16, and the aircraft took off with a takeoff distance of 412 meters, utilizing approximately 40% of the runway. The liftoff speed was achieved at 91 knots, with favorable weather conditions including a temperature of 14°C and gentle winds at 4 knots from 139 degrees.
As the aircraft gained altitude, it started its enroute climb, beginning overhead KFHR Friday Harbor Airport and rising from 848 feet to 29,061 feet in just 18 minutes, covering a distance of 62 nautical miles. The climb was a steep ascent, with an increase of 28,213 feet. Once at cruising altitude, the aircraft maintained a level cruise for 140 minutes, covering an impressive 744 nautical miles to the northwest of White Center, Washington.
The enroute descent began near Virgin, Utah, where the aircraft started descending from 29,176 feet to 7,429 feet over a 17-minute period, covering 87 nautical miles. After leveling off, the aircraft initiated its final approach to runway 21 at KGCN Grand Canyon National Park Airport from the northeast, heading 214 degrees at 3 nautical miles and 895 feet above ground level. Despite experiencing excessive threshold speed of 117 knots, the touch down was recorded to be far down the runway, taking up more than 50% of it, with a touchdown speed of 85 knots and a hard touchdown rate of -492 fpm.
The aircraft's runway touchdown position was slightly misaligned from the centreline by 5.4 meters. Taxiing to the parking area from the runway took around 4 minutes, covering a distance of 1 nautical mile. The aircraft ultimately covered a total flight distance of 898 nautical miles, taking a total of 184 minutes and consuming 196 kg of fuel.
A TBM 930 aircraft executed a final approach to runway 21 at Grand Canyon National Park Airport (KGCN) from the northeast direction, at a heading of 214.0° and 3 nautical miles away. The aircraft was cruising at an altitude of 895 feet above ground level (agl). The aircraft successfully landed on the runway, but the landing was far from being perfect.
One of the main issues with the landing was the excessively high threshold speed of 117 knots, far beyond what it should have been. This indicates that the pilot may have entered the flare a bit too late, resulting in a higher than necessary speed when crossing the threshold. Furthermore, the touchdown point was very long, using more than 50% of the available runway length. This means that the pilot could have done a better job of slowing down the aircraft before touching down, resulting in a shorter landing distance.
The touchdown speed of 85 knots was also too fast, contributing to the hard touchdown. The vertical descent rate of -492 feet per minute (fpm) further emphasizes the hard touchdown, which can put a lot of stress on the aircraft's landing gear.
In terms of alignment, the runway touchdown position was slightly misaligned by 5.4 meters from the centerline, which might not have been a significant issue in this case, but still needs attention. The most concerning issue, however, is the runway rollout alignment, which was significantly misaligned by 39.6 meters from the centerline. This suggests that the pilot may have been overcontrolling or undercorrecting during the rollout phase, resulting in a loss of directional control.
The local weather conditions at the time of the landing included a temperature of 22°C and a wind speed of 8 knots from 269°, with a crosswind component of 6 knots and a headwind component of 5 knots. This relatively stable weather did not seem to significantly affect the landing. Overall, the TBM 930's landing at KGCN's runway 21 fell short of optimal performance due to various issues with speed, touchdown points, and alignment.
