I have posted this picture and message on behalf of Mr Bob Birkett, Morecambe, England. he owns this jet.
This Hotspot has had less than 10 flights, it's last flight was made with wing tanks and powered by an AMT Netherlands Mercury turbine.
I have flown every flight, on this occasion during the flight I handed the box to a trainee, he proceeded to fly very well, without warning a loud bang was heard and a large piece of the aircraft fluttered to earth.
I immediately landed the aircraft and was shocked and amazed to see the damage.
Our English Graupner agent has told Bob Birkett there is nothing wrong with the kit and he is not prepared to do anything.
Ive heard rumours of this type of delamination in Hotspots before.
The reason for this posting is to warn others to reinforce the fuselage around the gear apertures and to ask if this has happened in the States, and what was the view of your Graupner agents ????
This should not happen, we were very lucky to get this aircraft back, you can imagine the result if the batteries had been in this area
