What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On February 15th, 2021 at approximately 1528LT, privacy data omitted, operated by privacy data omitted, was cleared for takeoff from Nashville International Airport?s runway 2L when the flight crew discovered the aircraft was still contaminated with ice and snow, despite having undergone a two-step deicing process.
The captain cancelled the takeoff clearance and the aircraft safely vacated the runway.
FFT7011 departed the gate at Nashville for the deicing pad where privacy data omittedcontracted deice vendor, privacy data omitted, was instructed by the captain to perform a two-step deice/anti-ice process. This request was made to remove a large accumulation of snow and ice from the night prior.
After spraying the aircraft, the privacy data omitted deicing crew notified the captain that the deicing process was completed and reported that the aircraft was clear and free of all contaminants.
When the aircraft arrived at runway 2L, it was cleared in position on the runway and given a takeoff clearance by the Nashville air traffic control tower (ATCT). After receipt of takeoff clearance, the captain performed the pre-takeoff check.
The captain?s pre-takeoff check indicated that the aircraft was not clear of all snow and ice contamination, and he subsequently canceled the takeoff clearance and vacated the runway. Upon returning to the deice pad for a second application of deice fluid, the privacy data omitted deice truck ran out of type I fluid. After a second unsuccessful attempt at deicing, the aircraft returned to the gate and the flight was cancelled.
This investigation revealed that the aircraft had a substantial amount of ice and snow contamination when it reached position on the takeoff runway. Analysis indicated the amount of contamination would have rendered the aircraft incapable of a safe takeoff.
There were no injuries and no damage to aircraft or airport property.
Note: the national transportation safety board (NTSB) was notified of the incident by AVP-100 personnel, but elected not to participate in this investigation.

As the FAA filed it
ON FEBRUARY 15TH, 2021 AT APPROXIMATELY 1528LT, ^PRIVACY DATA OMITTED^, OPERATED BY ^PRIVACY DATA OMITTED^, WAS CLEARED FOR TAKEOFF FROM NASHVILLE INTERNATIONAL AIRPORT?S RUNWAY 2L WHEN THE FLIGHT CREW DISCOVERED THE AIRCRAFT WAS STILL CONTAMINATED WITH ICE AND SNOW, DESPITE HAVING UNDERGONE A TWO-STEP DEICING PROCESS.
THE CAPTAIN CANCELLED THE TAKEOFF CLEARANCE AND THE AIRCRAFT SAFELY VACATED THE RUNWAY.
FFT7011 DEPARTED THE GATE AT NASHVILLE FOR THE DEICING PAD WHERE ^PRIVACY DATA OMITTED^CONTRACTED DEICE VENDOR, ^PRIVACY DATA OMITTED^, WAS INSTRUCTED BY THE CAPTAIN TO PERFORM A TWO-STEP DEICE/ANTI-ICE PROCESS. THIS REQUEST WAS MADE TO REMOVE A LARGE ACCUMULATION OF SNOW AND ICE FROM THE NIGHT PRIOR.
AFTER SPRAYING THE AIRCRAFT, THE ^PRIVACY DATA OMITTED^ DEICING CREW NOTIFIED THE CAPTAIN THAT THE DEICING PROCESS WAS COMPLETED AND REPORTED THAT THE AIRCRAFT WAS CLEAR AND FREE OF ALL CONTAMINANTS.
WHEN THE AIRCRAFT ARRIVED AT RUNWAY 2L, IT WAS CLEARED IN POSITION ON THE RUNWAY AND GIVEN A TAKEOFF CLEARANCE BY THE NASHVILLE AIR TRAFFIC CONTROL TOWER (ATCT). AFTER RECEIPT OF TAKEOFF CLEARANCE, THE CAPTAIN PERFORMED THE PRE-TAKEOFF CHECK.
THE CAPTAIN?S PRE-TAKEOFF CHECK INDICATED THAT THE AIRCRAFT WAS NOT CLEAR OF ALL SNOW AND ICE CONTAMINATION, AND HE SUBSEQUENTLY CANCELED THE TAKEOFF CLEARANCE AND VACATED THE RUNWAY. UPON RETURNING TO THE DEICE PAD FOR A SECOND APPLICATION OF DEICE FLUID, THE ^PRIVACY DATA OMITTED^ DEICE TRUCK RAN OUT OF TYPE I FLUID. AFTER A SECOND UNSUCCESSFUL ATTEMPT AT DEICING, THE AIRCRAFT RETURNED TO THE GATE AND THE FLIGHT WAS CANCELLED.
THIS INVESTIGATION REVEALED THAT THE AIRCRAFT HAD A SUBSTANTIAL AMOUNT OF ICE AND SNOW CONTAMINATION WHEN IT REACHED POSITION ON THE TAKEOFF RUNWAY. ANALYSIS INDICATED THE AMOUNT OF CONTAMINATION WOULD HAVE RENDERED THE AIRCRAFT INCAPABLE OF A SAFE TAKEOFF.
THERE WERE NO INJURIES AND NO DAMAGE TO AIRCRAFT OR AIRPORT PROPERTY.
NOTE: THE NATIONAL TRANSPORTATION SAFETY BOARD (NTSB) WAS NOTIFIED OF THE INCIDENT BY AVP-100 PERSONNEL, BUT ELECTED NOT TO PARTICIPATE IN THIS INVESTIGATION.
