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.

On July 11, 2019, at approximately 18:30 local time, aircraft N421DE a Cessna 421 on a part 91 flight with the pilot and two passengers landed at Timmerman airport, Milwaukee, WI (kmwc).

The flight was on an instrument flight rules (IFR) flight plan from shell lake (ksqq) to (kmwc) landing on a GPS approach runway 15L. When the aircraft attempted to turn from runway 15L onto taxiway d the aircraft right main and nose wheel exited the hard surface and the right prop struck the taxi light. The pilot stated: ?I chose not to use full flaps as we were experiencing some turbulence at lower altitudes. Entering the flare, I began to apply pressure to the pedals to align the nose for landing. When doing so, my seat slid backwards. I had adjusted the seat during flight and apparently the locking mechanism was not fully engaged. I believe the backward movement of the seat caused me to pull back on the yoke and the aircraft ballooned. I was able to safely settle the aircraft onto the runway and began applying the brakes. Unfortunately, in the full back position, I was not able to produce as much force on the pedals as I would if the seat was in the normal position. As I approached the end of the runway, I was carrying excess momentum. I was able to make the left-hand turn onto taxiway d, but the right wheel of the aircraft did leave the taxiway by a few feet. It was at that time that the propeller contacted a taxi light, resulting in damage to both the light and a prop blade in the aircraft,? No injuries were reported. The right prop blade had damage. VMC conditions prevailed at the time.

As the FAA filed it

ON JULY 11, 2019, AT APPROXIMATELY 18:30 LOCAL TIME, AIRCRAFT N421DE A CESSNA 421 ON A PART 91 FLIGHT WITH THE PILOT AND TWO PASSENGERS LANDED AT TIMMERMAN AIRPORT, MILWAUKEE, WI (KMWC).

THE FLIGHT WAS ON AN INSTRUMENT FLIGHT RULES (IFR) FLIGHT PLAN FROM SHELL LAKE (KSQQ) TO (KMWC) LANDING ON A GPS APPROACH RUNWAY 15L. WHEN THE AIRCRAFT ATTEMPTED TO TURN FROM RUNWAY 15L ONTO TAXIWAY D THE AIRCRAFT RIGHT MAIN AND NOSE WHEEL EXITED THE HARD SURFACE AND THE RIGHT PROP STRUCK THE TAXI LIGHT. THE PILOT STATED: ?I CHOSE NOT TO USE FULL FLAPS AS WE WERE EXPERIENCING SOME TURBULENCE AT LOWER ALTITUDES. ENTERING THE FLARE, I BEGAN TO APPLY PRESSURE TO THE PEDALS TO ALIGN THE NOSE FOR LANDING. WHEN DOING SO, MY SEAT SLID BACKWARDS. I HAD ADJUSTED THE SEAT DURING FLIGHT AND APPARENTLY THE LOCKING MECHANISM WAS NOT FULLY ENGAGED. I BELIEVE THE BACKWARD MOVEMENT OF THE SEAT CAUSED ME TO PULL BACK ON THE YOKE AND THE AIRCRAFT BALLOONED. I WAS ABLE TO SAFELY SETTLE THE AIRCRAFT ONTO THE RUNWAY AND BEGAN APPLYING THE BRAKES. UNFORTUNATELY, IN THE FULL BACK POSITION, I WAS NOT ABLE TO PRODUCE AS MUCH FORCE ON THE PEDALS AS I WOULD IF THE SEAT WAS IN THE NORMAL POSITION. AS I APPROACHED THE END OF THE RUNWAY, I WAS CARRYING EXCESS MOMENTUM. I WAS ABLE TO MAKE THE LEFT-HAND TURN ONTO TAXIWAY D, BUT THE RIGHT WHEEL OF THE AIRCRAFT DID LEAVE THE TAXIWAY BY A FEW FEET. IT WAS AT THAT TIME THAT THE PROPELLER CONTACTED A TAXI LIGHT, RESULTING IN DAMAGE TO BOTH THE LIGHT AND A PROP BLADE IN THE AIRCRAFT,? NO INJURIES WERE REPORTED. THE RIGHT PROP BLADE HAD DAMAGE. VMC CONDITIONS PREVAILED AT THE TIME.
