PT-22 Inverted Flight

[mikeh]

Hi

The 'Pilot's Flight Operating Instructions for Army model PT-22 Airplanes' section 11, Page 19, Point 19 Manoeuvres Prohibited, a. Inverted Flight.

Is this an airframe or engine limitation?

Does this exclude cuban eights and reverse cuban eights, which have brief inverted segments?

Thanks

HELLO,

I BOUGHT MY FIRST RYAN WHEN I WAS 18 YEARS OLD AND TRIED FOR TEN YEAR TO PULL IT APART IN THE AIR. I HAD A LOW LEVEL PERMIT FROM THE FAA DOWN TO 800 FEET AND WAS BELOW THAT MOST OF THE TIME. THE RYAN PT-22 ONLY DOES TWO ACRO THINGS

WELL AND THEY ARE SPINS AND SNAP ROLLS. I WOULD DIVE TO 140 MPH AND PULL THE STICK BACK HARD AND HOLD IT FOR TWO SNAP

ROLLS AND LET IT GO INTO A SPIN. IT RECOVERS WELL FROM A SPIN. YOU JUST NEED A LOT OF ROOM UNDER YOU TO KEEP FROM

MEETING THE GROUND. IT IS HARD TO PREFORM A GOOD LOOP WITHOUT IT LOOKING EGG SHAPED. AS FOR THE CUBIN EIGHTS AND OTHERMANEUVERS IT STRAINS THE KINNER BUT IT CAN BE DONE. WHEN IT COMES TO INVERTED FLIGHT, THE STICK IS AGAINST THE FORWARDSTOP AND THE RYAN IS STILL COMING DOWN WITH THE KINNER WINDMILLING. MAYBE THAT IS WHY IT IS PROHIBITED AGAINST

INVERTED FLIGHT.

I ALSO HAD A RYAN WITH A LYCOMING R-680-13 (300 HP) AND IT DID MUCH BETTER WITH THE EXTRA HORSES BUT WAS ABOUT THE

SAME WHEN IT CAME TO INVERTED FLIGHT EVEN WITH THE INVERTED FUEL SYSTEM. IT FLEW ABOUT THE SAME AS THE STOCK RYAN BUT

THE EXTRA HORSE POWER MADE IT CLIMB LIKE A HOME SICK ANGEL.

I NOW HAVE THE SAME RYAN BACK AGAIN THAT I BOUGHT WHEN I WAS 18 YEARS OLD (N47541) AND THE ONLY MANEUVERS I DO ARE

TAKE OFF , SHALLOW TURNS AND LANDING. BEING 70 YEARS OLD SEEMS TO MAKE A DIFFERENCE IN THE WAY I LOOK AT LIFE NOW.

BEST REGARDS TO ALL,
