A true Whirlwind 3 story, at least I was told it was!
An instructor was taking a 705 student down to Predannack at 500 feet when the student asked what happens if the hydraulic fails in the cruise or faster. Now remember the requirement for hydraulics off was around 50 or 60 kts which is below the cruise speed. The instructor sped up to 90 kts & switched the hydraulics off. The nose pitched up & the 3 banked sharply to the left, making a perfect descending barrel roll & ended up tearing along a field at 60 kts! A typical granite Cornish hedge then stopped their forward motion very suddenly. The 2 pilots still strapped in their seats & the instrument panel took off clearing the hedge & ended up sitting side by side in the next field unscathed! The OAT gauge stuck in the tree about 25 yards away like a spear.
The instructor is reputed to have said " & that is what happens if you switch off the hydraulics going too fast"!
I'm assured this is true! Maybe bastOn knows more as this happened a few courses before us.
