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.

No NTSB id listed because NTSB is not investigating.

Aircraft was on a training flight when the crew smelled smoke and then saw smoke in the cockpit. They made an off-airport landing on a residential road with no damage to the aircraft or injuries.

The operator’s statement from the pilot: “the amount of smoke in the aircraft was enough to create a haze in the flight deck. If we had not opened the window and opened air vents there would have been enough to begin to impede visibility through the windscreen. Prior to the smoke entering the cabin we had a burning smell.”

After landing the aircraft was dismantled and moved to privacy data omitted facility.

When we arrived at the privacy data omitted facility the aircraft was still dismantled for transport and the interior had been removed but the instrument panel had not been taken apart. We watched as their chief inspector removed the primary flight display (PFD) and the cooling fan mounted behind the PFD. There was no damage to the wiring to the cooling fan and power was still present. The fan smelled burnt and had some dust

And soot on the blower wheel which was free to turn. They demonstrated that the blower would not run when powered.

Operator filed an SDR, number 2024FA0000673, and sent the blower assembly to the manufacturer of blower model SAFE328, p/n: 305467-00 for teardown and their service work order states “found blower internal circuit card burned, scortch marks and soot.”

As the FAA filed it

NO NTSB ID LISTED BECAUSE NTSB IS NOT INVESTIGATING.

AIRCRAFT WAS ON A TRAINING FLIGHT WHEN THE CREW SMELLED SMOKE AND THEN SAW SMOKE IN THE COCKPIT. THEY MADE AN OFF-AIRPORT LANDING ON A RESIDENTIAL ROAD WITH NO DAMAGE TO THE AIRCRAFT OR INJURIES.

THE OPERATOR’S STATEMENT FROM THE PILOT: “THE AMOUNT OF SMOKE IN THE AIRCRAFT WAS ENOUGH TO CREATE A HAZE IN THE FLIGHT DECK. IF WE HAD NOT OPENED THE WINDOW AND OPENED AIR VENTS THERE WOULD HAVE BEEN ENOUGH TO BEGIN TO IMPEDE VISIBILITY THROUGH THE WINDSCREEN. PRIOR TO THE SMOKE ENTERING THE CABIN WE HAD A BURNING SMELL.”

AFTER LANDING THE AIRCRAFT WAS DISMANTLED AND MOVED TO ^PRIVACY DATA OMITTED^ FACILITY.

WHEN WE ARRIVED AT THE ^PRIVACY DATA OMITTED^ FACILITY THE AIRCRAFT WAS STILL DISMANTLED FOR TRANSPORT AND THE INTERIOR HAD BEEN REMOVED BUT THE INSTRUMENT PANEL HAD NOT BEEN TAKEN APART. WE WATCHED AS THEIR CHIEF INSPECTOR REMOVED THE PRIMARY FLIGHT DISPLAY (PFD) AND THE COOLING FAN MOUNTED BEHIND THE PFD. THERE WAS NO DAMAGE TO THE WIRING TO THE COOLING FAN AND POWER WAS STILL PRESENT. THE FAN SMELLED BURNT AND HAD SOME DUST

AND SOOT ON THE BLOWER WHEEL WHICH WAS FREE TO TURN. THEY DEMONSTRATED THAT THE BLOWER WOULD NOT RUN WHEN POWERED.

OPERATOR FILED AN SDR, NUMBER 2024FA0000673, AND SENT THE BLOWER ASSEMBLY TO THE MANUFACTURER OF BLOWER MODEL SAFE328, P/N: 305467-00 FOR TEARDOWN AND THEIR SERVICE WORK ORDER STATES “FOUND BLOWER INTERNAL CIRCUIT CARD BURNED, SCORTCH MARKS AND SOOT.”
