Recently read that . at a display at Ardmore a PL12 was flown the runway length inverted. Must have been many years ago .
Anyone have any photographs of the event?.Think it may have been Nigel Arkely flying .

Seems . . . unlikely?
I would assume that the PL-12 would not have an inverted fuel or oil system?

Yes that does seem a bit farfetched, maybe a brief roll to the inverted and back again but I can't imagine it would be too happy to sustain inverted flight for anything more than a few seconds? Mind you, the PL-12 doesn't look like it should be able to fly at all so I guess anything is possible.  |

Thanks for the responses .Did have doubts also .the author of the article is a well known aviation identity.living in the Waikato.

Was there a crash at the end?

Just a story I think, although the aircraft is quite capable of aerobatics. A topdressing aircraft would be placarded that it was not to be used for aerobatics. I saw the Piper Super Cub master do a display one year in an Airtruk but he never got the aircraft upside down or near to it. On the other hand I once saw a film of an Airtruk doing aerobatics, so it can be done.

Most aircraft can "do" aerobatics. Its just the next poor bastard who gets in that may suffer the consequences! Sustained negative g flight at low level unlikely

PL 12's always look like they're flying upsidedown...  |

The Tiara engined PL12 was fuel injected.
I once saw a James Fletcher looping its way towards Hamilton,after 20 or so loops its resumed level flight.

Airtrucks were stressed to something like 6 positive and negative , the factory pilot used to aerobat them frequently. They have very responsive and nicely harmonised controls and are delight to fly. They had all sorts of engine installations from 520 Continentals through to 720 Lyc's, most fuel injected. They did not have inverted systems either fuel or oil sump but would be capable of short periods of inverted flight. The same way a Spitfire had neither but if you see any of the test flying by Alex Henshaw or Penrose (I think ) you will see how an aircraft without inverted systems can cope.

And, properly set up and calibrated, provide absolutely the finest spraying office there ever was. Can see the ground ten feet in front of the aeroplane and overhead wires six inches! But, if you've an imagination and have lost a friend that way, the image of the nose-wheel coming off and the airy turning over on your head becomes more vivid with every passing day. B A |
