Re: Stearman talls after takeoff
Hard to believe that he was doing 80mph. Think he stalled it with a too high AOA after lift off.

Re: Stearman talls after takeoff
The guys last flight review was Sept 2022, which means he was not current. 
The insurance company is not going to love him.
That gear is very strong……

Re: Stearman talls after takeoff
Looks to me like a botched approach?
The Stearman’s stall characteristics are very benign, you really have to abuse her to get her to fully let go. The approach to stall is also very gentle with ample warning and mild mannered buffet.
With what Mike says regarding his last flight review, the accident ties in with the trend of not being the actual loss of desired aircraft state (the CRM term), but the bad handling of the recovery leading to the crash. Him being so far out of recency that he botched the approach, got the aircraft in an undesirable aircraft state and failed to execute the correct maneuver to rectify it.

Re: Stearman talls after takeoff
If the trees were a little further from the runway he might have had a second go, I guess. Definitely fell behind the drag curve on that approach though..

Re: Stearman talls after takeoff
The pilot seems to imply that the ASI was broken and only showing 80Mph consistently.
Would a one way valve in the Pitot system create the situation where the ASI would show max speed attained by allowing pressure to build and not release?
Could some debris in the pitot system create a one way valve by being pushed in and then getting stuck there, not releasing the pressure?
Would be interested to hear if anyone has suffered from a faulty ASI and what caused it, regards Karl

Re: Stearman talls after takeoff
If the ASI was broken, surely the ROD and AOA should have given ample warning that the indicated airspeed he saw was not correct.

Re: Stearman talls after takeoff
My thought's as well Karl. I think it most unlikely that aircraft was doing 80.Karl.Drogemoller wrote: Mon Jan 13, 2025 3:48 pm The pilot seems to imply that the ASI was broken and only showing 80Mph consistently.

Indeed a bug in the pitot could have blocked it completely when it was doing 80.

Re: Stearman talls after takeoff
A 24 000 hour pilot can't feel when his aerie is dangerously slow and hanging on its prop ?
Come on, does he even look at the ASI ?

Re: Stearman talls after takeoff
Ricardo - a guy doesn't get that number of hours from flying PCs. He's an airline pilot. And from the video, if he could feel he was dangerously slow why didn't he do anything about it? Lower the nose or increase power - or both.richard C wrote: Tue Jan 14, 2025 10:33 am A 24 000 hour pilot can't feel when his aerie is dangerously slow and hanging on its prop ?

Re: Stearman talls after takeoff
Another observation: if he'd maintained proper runway heading, he'd have had a chance at landing on the runway (airstrip), wouldn't he?
