Shock Absorber on M20F

[Barneyw]

Hi all

Someone damaged the nose wheel "Leg Assy" by over steering. I think this part is also known as a "Truss" My nose wheel has an extra shock absorber fitted.

Anyhow my understanding is that the shock absorber is unique to the "F" and therefore requires a unique "Truss". I just got. off the phone with Lasar and they inform me that they rarely see this type of truss. ATM there is nothing second hand available.

Can anyone tell me a little bit of the history of the shock absorber on the "F" and if it is still needed given that Lasar told me the only "early version" of the truss is available without mounting holes. I'm assuming it is not required.

Look forward to your replies.

Cheers

PS I have tried to ring Mooney about this but no answer for now.

Many of our older Mooneys once had a shock absorber on the nose wheel; my 1970 C has the (empty) brackets on the leg.

Apparently Mooney decided they were not necessary, and they quit putting them on at some point. There may be an SB allowing it's removal. I've owned my C since 2007, there was no shock when I bought it.

I believe there is an SB to remove it. Mooney states something along the lines of " serves no useful purpose". At least this is true for my C model.

A picture would help, but it’s probably the thing that’s not required.

Call South West Texas Aviation.  They also repair the leg via welding and heat treat. It was a year ago now, but I sent them a leg from my F model and while it did not have the shock absorber installed, it did have the extra hole in the leg.  Maybe you'll get lucky!

I threw my shock away in 1989.

There is an Engineering Drawing that allows removal.  You won't find it in the Service Bulletins.  @Andy95W posted it a couple years ago but the link no longer works.

Maybe he can post it again.  Don't forget to revise the Weight and Balance when you remove it.  It is over 2 lbs on the nose.

The nose gear has three parts. The upper part is the truss, the middle part(which is the part that gets damaged by oversteering) is the leg, and the lower part is the spindle. But everybody seems to call the leg a truss.

Yes the terms seem to be interchangeable but you are correct.

Hi Barney,

I had also had a shock absorber the same as yours on the nose wheel of my J when I bought it 25 years ago. My Mooney was looked after in those days by Hamish Ramsay (who has since retired) at YWGT and I recall him suggesting he remove it as Cfidave suggested, Mooney considered it to serve no useful purpose and authorised the removal if desired, so that is what Hamish did.

I forgot about it until I just read your thread.
