Glad all are ok.

Other sources suggest the little 'grub' lost a prop blade and made a forced landing without drama, after narrowly missing the school and nuclear power station etc of course!

There is one big school, it`s between the North & South airfields - "Sleaford Tec" of course! (or is it called Sleaford Community College these days)

Cranwell aircraft down
Hope it wasn't a chop ride!

Hi Dixb
Thanks for that - hope they sort it out soon as due to fly soon. At this rate we will all be out of currency:(!! HF |
...You mean like the Greeks!!....I'll get my coat ;)

The rumour I'm hearing is that it's another occurence of this...
http://www.aaib.gov.uk/cms_resources...pdf_030406.pdf ...should have bought the T67!!! |
...should have bought the T67!!! |
Leon, would that be the Firefly which uses an extremely similar Lycoming/Hoffman combination to the Tutor? :eek:
|
The firefly which had a bigger engine and a different prop.
|
Cows get bigger
No that would be the T67 with nearly 60% more horsepower and a better prop to handle the torque. In fact it was a better aircraft all around, but someone in the procurement cycle was allegedly bought off by Herr Grob along the way :sad: Better still was the delightful Bulldog, shame it was overengineered and overpriced as Beagle (not the Pruner) and Scottish Aviation had a real winner on its hands.

Change the prop !
If this is another problem with the prop and at the moment it is a BIG IF then it should not be too hard to change the prop.
A number of manufacturers have props that are fitted to this engine who would jump at the chance of an order for 120 units plus a few spare. Add the maintenance contract for prop overhaul and I am sure the package would be big enough to get the manufacture to get the certification done for next to zero cost. The likelihood is that with the advances in blade technology the aircraft performance would also be increased. |
Would that be the Firefly that the US got rid of because of spinning incidents?
Duncs:ok: |
Not just got rid of but physically crushed complete with the engines and avionics still in them.
http://www.aero-news.net/images/cont...ap-0609-1a.jpg Hondo Aircraft Destroyed All of RAF fireflies came through us for acceptance, as well as the replacemt trials including the Grob, we were suprised it was the winner. |
For some reason the yankee T67 had a smaller rudder than ours (t67m260) - never came out in the subsequent investigations though. So hardly surprising that they had some spin recovery problems! :ugh:

Here's a T-3A

Photos made a day after the incident are now at

Looks a good result, there was a aircraft shed a blade a while back at Tollerton while doing circuit and bumps, as he touched down opened the throttle a blade departed, the engine controls he was holding ripped themselves out through the firewall as the engine tried to depart the aircraft.

The difference in engine output between the -A and -M would necessitate the difference in rudder you note above. ISTR the USAF losses were entirely due to the way they handled the aircraft, rather than any specific design/build issue. T67M way superior to the Grob but that's all history anyhow. |
