Other than the fact it was a BEA report, I agree. The slope of the fracture surface (angled forward from top to bottom) is opposite that of the BEA starboard side fracture line and bears no resemblance to the port side fracture line along which the tail on that other aircraft actually separated.

I think if I had a G202, I would be thinking about how to assure myself that the aft fuselage still had good structural integrity. How best to do that is the rub.

The NTSB recommendations should be interesting to a wide audience.

Reports

As you can imagine, we all Giles and MX owners are bunching together for information...i just finished performing a tap test on mine all day long...not much else can be done. I may do an Xray on mine if I can convince my MRO to let me do it without formal guidance other than snap film all over the tail. We already got reports from the field. We got the best of the best w Giles/MX experience helping the Feds..not going to speculate until the oficial report but it is pointing towards failure during original assembly by private individual + pre existing tail damage history not properly repaired. Also there was a SL feom Akrotech that required an inspection and modificatio in the tail. It is not clear if Andrews had it or not performed...Lets wait for results...no Akrotech build Giles kit have ever failed and one in 70 + made without a strctural problem, is not a solid indication of a wide fleet problem. I know of more certified aircraft w enough problems flow by the Pro,s here that need reasurance as well everytime they are flown. Unfortunatelly some of thos horrific scenes are not shown as Drews fatal accident!

Sorry

Patrikal. Sorry you had to witness the dead of a good friend doing what he liked best. drew was very capable pilot and safety was always his first priority. No one expect any of these to happen. We all prepare for the worst and honestly I dont think he comprehended until it was too late to bail out what was happening! For us acro flyers, the nano second the aircraft doent do what it is supposed to do, you must act fast! Most of us apply the PARE emergency procedure immediatelly then your options are bail out after jettision the canopy. At low altitude ther is not much choice...

It's a 15 year old airframe. Wouldn't any failure during original assembly have manifested long time ago?

Also, I don't know how exactly they are assembled, but the accident video is showing a break roughly at a 45 degree angle to the main axis. It would be a strange orientation for an assembly joint.

Not really? Lets asume they forgot to glue the rear rib to the upper shell in other words at 75% or less of designed strenght. It will take a while to break. how about a series of rescent hard landing cracking the first layers of the CF bottom fuselage shell? How about a damage history not properly repaired? If CF strands are damaged, the strenght is gone! Do you have any ideas how Giles are made? Im asking not to ne ugly..just a simple question. Lets not speculate w unfunded rumors or conspiracy theories! Wait for results !!! A 35000 cicle 787 is not any unsafer than a brand new right? There are no old aircraft! Just those maintained incorrectly otherwise lets go ahead and close all airport flying older thant 15 year old aircfraft tomorrrow..lots of Fibergalss and carbon fiber aircraft flying in the US for the las 30 years...every weekend during spring summer and fall in the us we have CF aircraft flying..Ron Holland just won the World Champion in Free Style again for the 3rd time in a row flying the same exact tail. .let,s not panick...I fly a Giles 202 six s/n earlier that Drew,s. I do have a vested interest to find out what happened more than anyone here..

Hamster...also thats the flaw I was pointing earlier with the French build CAP 222 and the Giles. The angle and direction break in Drews Aircraft is consistent with a Doubler behind that holds the Vertical STabilizer. The break in Drew,s starts from below and upwards against a very strongh well built tail when properly assembled and or mantained, That tail boom bottom was weakened by something and we all want to find out why? Water, chemichals, damage, debonding, cracks, etc....

It appears that Vne of 220 Kias before pull was heavily exceeded

there are no old low-level aerobatic pilots.
The last one I knew recently crashed with an old certified full metal piper going straight and level but with a leak in the exhaust resulting in a CO poisoning...
So arguably he is no longer an old low-level aerobatic pilot, but not because of that.
It´s not always the obviously dangerous which kills you.

I would not discount flutter in this accident. My first thought was flutter when I saw the video. Violent and sudden!
