I haven't heard of an issue with studs breaking on 9 series engines, where did you read that?

Second pic shows Hawks (the Gnat's succesor)

Facebook, can't see it. Does he post elsewhere?

Detail is important ..Quote " no component cost to the customer." Removal of engine, complete strip of engine and rebuild with new crank plus any transport costs involved in shipping parts/engines aint gonna be cheap.

Take off Run 200m?, riiiight🤣

Lycoming I-0-540 No idea why that first spec says M14-P as they are 9 cylinder Radial engines and one look at the picture tells you they aint radials on that bird .

Yea and the ride is cr@p, really harsh and you lose grip as the tyre doesnt deform and comply to the surface. You can also get Mousse foam inserts for off road motorcycles, Ive used them and again the ride and grip is reduced, plus they are bu99ers to fit and eventually break down. There is nothing to compete with gas filled tyres on any vehicle, just that the risk of punctures is always there Aviation wise, id still say there is nothing that provides the same shock absorption as a gas fill and as you say, weight can't be bettered

Groundspeed or airspeed?, had a bit of a tailwind there😁 Nah seriously thats silly fast, I dont know how you keep track of which way its pointing

..and different N-Registrations too. Seems either one was a complete rebuild and re-register of the other or 2 different airframes that shared the same type name

Do applications for this ASIC thing get vetted or is it purely a paper exercise?

RR, I notice you use the words "Anti Puncture" as oppossed to puncture repair. Are you referring perhaps to products like Slime?. I have experience of Slime and other similar products in Mountain Bike tyres and they are effective on small punctures but they dont half leave a mess inside the tube or tubeless tyre. I would steer clear of these products. Are your Aircraft tyres tubed or tubeless? If tubeless and you were actually asking about repair and not prevention, then the motorcycle Plug type repair kits work really well in my experience.

But you (and apparently everyone else here) is dismissing the fact that the mechanical pump was also still operating in this scenario but with an open outlet valve. I'm baffled that apparently nobody else (except the blokes who conducted the investigation) can see how that can reduce pressure.

Skippy you have misunderstood, we are talking about the outlet valve in the mechanical pump failing open. I'm gonna leave this, busy today maybe Nev can explain P.S. its highly unlikely that is your problem anyway.

Of course It wont make the boost pump fail, but If the outlet valve remains open during the suction stroke then it will suck fuel back through the outlet thus reducing pressure overall.

Pardon?
