Another gear-up this afternoon


Recommended Posts

Just got this sent to me from some friends out at KEET. No apparent injuries except for ego. Picture shared by pilot on social media.

Don't have any information as to reason for the gear up landing.

Prop looks bent to me, but then I have an Ipad, not a full size screen.

‘I don’t think you could get it to stop in the right place, first you have to get it to stop windmilling which isn’t as easy as you may suspect, mine always stops at 10 and 4 like an airplane that you hand prop.

But it appears the flaps are up, so maybe they couldn’t get the gear down?

Same I’m also on an iPad mini.  That’s funny, my prop either stops at 12 and 6 or 3 and 9.

First one for the spring flying season?

Lets all do a Gumps check...   :)

 

1) Gas...

2) Under carriage...

3) Mixture...

4) Prop...

5) Switches...

 

Well....   looks like he got the first one right.

Not enough definition to the pic to tell how bent the prop is...

When idle, prop tips usually get bent back...

If generating power, tips grab the ground and pull forwards... bending the forwards.

 

PP thoughts only...

It also kinda looks like the prop is at coarse pitch, which is unusual.

 

Once they contact the ground all bets are off. Once oil pressure is removed from a prop, it will go to fine pitch, except for an aerobatic prop or a turbine, they go to high pitch or feather, unless they contact something, then who knows?

I did a Travel Air and saved both props   No0t difficult to flatten two blades.   Now three blades ????

last flight was in April according to FlightAware

As far as...

Mooneys with no oil pressure having the props go to Max blade angle...

There are two...

Rocket engineering...  Rocket and the Missile both go towards feathered position when OilP goes to zero...

Great during engine out situations at altitude...

Not so good if engine governor oil pressure goes to zero during T/O...

PP thoughts only, not a mechanic...

When you see the before picture...

The blade tips are decorated in a way that may make the fuzzy after pic look like they are damaged more than usual blade tip decorations...

+1 for mixing Vettes and Mooneys...

Are most gear ups from forgetting to put them down? 

If so then how frequently are they mechanical failure as in won’t go down? I assume some collapses are due to hard landings etc?

Trying to get a sense of how often it’s a broken airplane as opposed to pilot error.

‘Coming from a C-210 as my last complex airplane, it was often the airplanes fault, at least to some extent.

My guess is that in general they skew towards pilot error. Mechanical failures are likely more prevalent in certain models. I know of a C177 that had back to back mechanical gear failures. Insurance company was off the hook for the second.

We are seeing one GU each week...

once each year, something mechanical has been improperly set up...

once per month, a gear down lock block has been worn, and the thumb nail test wasn’t used properly...

So....

Expect most of the GU accidents to occur... from failure to use the triple GUMPs procedure...

Oddly,   Most of the GU landings reported are from non-MSers....

 

There are sooo many ways to avoid a GU landing...

Find the combination that works for you...

PP thoughts on estimated reports regarding GU landings around here...

To further update the brain trust:

I made a mistake in the original post - the gear up was on TO. He had allegedly done some work behind the panel and was taking it to a mechanic. The gear handle was in the down position after he exited the plane, but the circuit breaker was popped. Several thoughts voiced at the airport about the apparent anomaly of a gear up on take off with the CB popped and the gear handle in the down position, and not all of them were complimentary.

@carusoam, what is a thumb nail test?

Can you run this by me one more time?  What am I missing?

Gear handle was DOWN.  The mishap was on TO (takeoff??) but he exited the plane????

If it was on takeoff, I'm guessing you're saying that he lifted off or bounced off the runway and the gear retracted and he settled back down onto the runway?  But I'm still missing the circuit breaker being popped.  So if the there is no power to the motor, how did the gear retract?  Did they swing freely somehow so that they were not still locked in the down position?
