why didn't CASA airworthiness notice this when the Bristell was approved for student training?

If, as claimed in the report, some instructors said the Bristell would drop a wing in the stall, then could this be an airworthiness issue? After all, there are certification rules that govern wing drop tolerances.

POH is as follows; Balked Landing (Go around) 1. Throttle - full power (max.5800 rpm) 2. Wing flaps - extend as needed 3. Trim - adjust as needed 4. Wing flaps - retract at height of 150 ft after reaching 120 km/h (65 KIAS) 5. Trim - adjust 6. Repeat circuit pattern and landing Not really, the requirement is for the test pilot to be able to prevent the wing drop exceeding specified amounts - that is test pilot, not just an instructor let alone a student pilot. Is this at idle power? if not, how much power has to be used to meet certification requirements? Seems to me a grey area when it comes to LSA certification as against non LSA types.

Either an aeroplane drops a wing at point of stall or it doesn't.

Seems a perculiarly written go-around procedure. Is that a manufacturer's POH or a flying school document? Extending flap in a go-around is most odd. Similarly all this advice about trimming doesn't sound like a manufacturer's language as trimming should be normal airmanship? Also use of 150 ft seems a bit dodgy when most height restrictions are in whole numbers e.g. 200 feet. As for "Repeat circuit pattern and landing" what a strange addition to a go-around

I’m impressed that you were one of the lucky ones that actually got a CPL from there!

Not a grey area at all as it seems to me that the requirements are quite clear. |

Thanks David. That certainly clears things up for me.

Be interesting to see if these findings play a role in the class action.
What's the latest rumour in regards to the Class Action against BHI/Soar? everything's gone really quiet on that front, did the mediation in March go ahead? |
Foxbat bashing has been soarly missed.

Centaurus, I like everything you say. In my experience a go around from the flare or a bounce usually needs considerable forward stick force as power is applied and airspeed is regained. Quickly followed by adjustment of trim and flap. I doubt this is ever taught.

Wing flaps - retract at height of 150 ft after reaching 120 km/h (65 KIAS) 5. Trim - adjust 6. Repeat circuit pattern and landing I once witnessed a student conduct 4 go-rounds during a first solo and then land perfectly, he just didn't feel happy with the first few attempts. I had a student on second solo once have crosswind increase slightly above his comfort level, so he went around, and requested the crossing runway to land. It might be assumed a pilot has airmanship, but if an aircraft has a sneaky bite to it, why not include it in the procedure. The wing flaps extend part is the more peculiar statement, but I don't know this type. The additive "Repeat circuit pattern and landing" says to me, don't attempt to save the landing, just do another circuit. I was never a fan of teaching students to catch balloons/bounces and try to land extending landing distance and increasing the chances of mishaps. Go-round should be part of a solo check as much as each landing is. |

Pretty sure some airline sim instructors have had to remind some quite high time pilots to trim during approaches and go-rounds, I've heard it in many a debrief.[/color]
