Apparently flipped by wind gust ??? as it was taxiing ??

Listening to the tapes, sounds like Thunderbird 8 went off the end (or side) of runway 6L after an ILS approach with heavy weather in the vicinity.

Thunderbird 8 is normally the callsign of the advance pilot and narrator.

T-bird 8 had earlier shot a missed approach to 24R with reports of extreme precip and windshear in the vicinity of the DAY airport. He discussed diverting for fuel and called his ops while he was loitering in the MOA between approaches. He decided to try an ILS to 6L, requested 'short vectors'. Tower winds reported 340/13G21, RVR 6000+.

After landing T-bird 8 reported that they were in the overrun. News reports said the aircraft was inverted and the occupant extrication may have been lengthy.

Time of the mishap was around 1630Z from the recordings.

Hmm that's an interesting one... Any idea what kind of wind could do that!?

Airbubba 23rd Jun 2017 21:54

Good news from Thunderbird 1's press conference, both pilot and backseater are in good condition. :ok:

Pilot is Captain Erik 'Speedy' Gonsalves, he was giving a fam flight to aircraft maintainer Tech Sergeant Kenneth Cordova. Both were conscious and talking during the lengthy extrication. Since they were sitting upside down on hot ejection seats, I'm glad that the effort was not unduly hurried by circumstances.

As usual, some of the questions in an earlier media briefing given by airshow and airport officials were perhaps not well phrased. When asked if the aircraft occupants were pilots, one of the briefers said that we know that at least one was. When asked if the crew attempted to eject after the plane rolled inverted on the ground it was intimated that the ejection vector might not have been favorable in that situation so the answer was probably no.

During the 5 pm media conference Lead Thunderbird Lieutenant Colonel Jason Heard received word that the T-birds would NOT fly in the show on Saturday. Participation in Sunday's Dayton show would be decided later. He seemed pleased and not surprised by the decision as he looked at his phone on the podium. I sense that his input to the decision was in line with the result in this case.

Fast jets are not immune to the effects of poor weather. Landing in heavy rain with heavy precip and gusty winds is always demanding. I am sure the reasons will be fully reported but, I would guess aquaplaning and loss of directional control might be a possibility. Also, these big Int'l airport runways can have a lot of slippery rubber deposits that can bite a little jet! :uhoh:
Very pleased to hear both occupants are OK. :ok:

Looks like it's on the grass. If the aircraft left the hard surface with some sideways drift, it wouldn't take much to dig a wheel in. The F-16 has a fairly narrow track undercarriage.

Curious to know if the F-16 has anti-skid. We had an F-86 in eastern Canada do a runway overrun a few years ago during a rainy landing. No anti-skid and apparently vulnerable to this sort of thing. Apparently did a practice run with weather approaching. Both arrived at the airport at the same time.

Did anybody call International Rescue?

Oh, my coat and hat! Thank you.

Yes, all F-16's have anti-skid with backup mode being a pulsating mode which reduces brakes effectiveness but will spare you from locking up the wheels. Last but not least you can go full manual braking with no protection.

Looks like the Sunday show in Dayton is cancelled as well. :sad:

From the T-bird Facebook page:


Update 4:

The United States Air Force Thunderbirds will not fly at the Dayton Air Show on Sunday. We would like to thank our fans and the air show staff for their continuous support.

Capt. Gonsalves has not been released from the hospital. Stay tuned to our social media accounts for more updates.

Are they expected at RIAT?

They are certainly scheduled to be there this year. And they are also supposed to do a Bastille Day fly-over in Paris as well.

I would think loss of the number 8 plane with minor injuries would not be a showstopper. At least I hope not...

B2N2 25th Jun 2017 21:29

No doubt they have a safety stand down or equivalent.

Airbubba 27th Jun 2017 01:16

Looks like the show schedule is back on the road. :ok:


UPDATE 5:

The United States Air Force Thunderbirds will return to flying operations today, June 26th when the squadron departs Dayton, Ohio for home station at Nellis Air Force Base, Nevada. The team will conduct routine practices on Tuesday.

"Capt. Gonsalves remains in the hospital and is surrounded by loved ones," said Lt. Col. Jason Heard. "I have full faith and confidence in our team to conduct the mission safely, we look forward to returning to flying operations."

Thanks for the continuous support.

A nice clip of TODAY show host Lilliana Vazquez as she takes a ride with Captain Gonsalves in Thunderbird 8 a couple of weeks ago. She enjoyed every bit of it she says. :ok: There is a picture of Captain Gonsalves recovering in the Dayton hospital at the end of the clip:

Any info as of what happened?

On a side note I'm impressed about the scheduled displays in Europe. It must be quite an expensive logistical undertaking...

ehwatezedoing 29th Jun 2017 16:45

Reading Thunderbirds Facebook's feed, somebody wrote down that the nose gear wasn't down (or something of that matter) Followed by lost of directional control.


I would take that with a big grain of salt though...

Investigation: Pilot Landing Too Quickly, Heavy Rain Caused June F-16 Crash 03 Nov 2017 Brian Everstine

"​A USAF Thunderbird F-16 was destroyed while landing in June in Dayton, Ohio, because the pilot touched down going too quickly for the rainy conditions, an Air Combat Command investigation found.

On June 23, an F-16D, tail number 91-0466, from the Air Force’s Air Demonstration Squadron of the 57th Wing at Nellis AFB, Nev., was flying a “familiarization sortie” at James M. Cox Dayton International Airport with a member of the team’s crew in the back seat....

USAF: http://www.airforcemag.com/AircraftA...16D_Dayton.pdf (1.24Mb)

...The pilot made no attempt to eject, and was stuck in the aircraft as rescuers were forced to cut through the canopy to get the pilot. The pilot sustained several injuries and was taken to a nearby hospital. The crew member in the back seat was not injured.

The F-16 was destroyed in the mishap, at a total loss of $29.2 million.

While the AIB president found the main cause of the crash was the pilot landing with excess airspeed, the board also found other contributions to the mishap were environmental conditions affecting the pilot’s vision, a misperception of the changing environment, and the pilot not following procedure for braking on a wet runway."

The pilot considered the crosswinds at the airport and decided to fly a faster approach of 160-165 knots. The aircraft’s data recorder, however, showed the F-16 crossed the runway approach end threshold at 193 knots. which “significantly increased the distance required to land” the F-16, according to the ACC Accident Investigation Board report released Friday.

The F-16 touched down about 4,764 feet down the wet runway at a speed of 25 knots above computed touchdown speed, leaving 6,137 feet of prepared surface left. The pilot was unable to stop and entered the overrun at 50 knots, overturning in the grass.
It surprises me that a pilot, of such quality as to be a member of the Thunderbirds team, deliberately landed so fast - was something causing the ASI to under read?
