Does anyone have information about an off field landing of an RV-10 in the west about 2 weeks ago? I heard from a local pilot that a -10 that had recently visited SBP (San Luis Obispo) then later in the week made a forced landing due to engine failure. The local pilot had strong feelings that the failure was related to fuel vapor lock.   

I am sorry for the sketchy information but it would be of benefit to learn the particulars.

James Rore (N728DD), Albert Cook (N329BC), Leroy Williams (N231LD), Ed McGinty (N770BD), Mark Christiansen (N104ML), Doug Petersen (N410DP), or  Randy DeBauw (N610RV) would be the seven logicals on the West Coast (from the builder names in my database).  Sounds like Randy is fine.  Mark are you out there?

I just ran the NTSB stats for the last two months. About 25 accidents/incidents for homebuilts but no RV10s.

Might not have been reported.



Even if it did not happen, or was not fuel system

related it is worth mentioning that it is shaping up

to be a hot summer.



As was discussed earlier - autofuel has higher vapor

pressure but even 100LL can run into problems. High

alt, high temp (+ a hot tunnel) can contribute. I

believe the Eggenfellner crowd discovered one weakness

of pumps is they will not pump vapor... One of the

reasons I'm considering a return line to the tank (New

ECi systems requires this). More flow of "cool" fuel

and an outlet for vapor.



Perhaps someone has or could build a table of fuel

temp, altitude and risk of vapor lock? anyone measure

fuel temps at the pump or ?  I think the conclusion of

the Egg crowd was to minimize any obstructions before

the pump inlet (as this is usually at an even lower

pressure). They also added a bypass line to the fuel

rail to allow some fuel (or vapor) to bypass the

regulator. Weakness of an auto regulator is it will

hold vapor just as well as fuel at line pressure....

Car's solved this problem years ago - they put the

high pressure pump in the gas tank and also use a

check valve to maintain line pressure. This keeps line

pressurized even with high vapor pressure winter mix

in hot climates.



Petersen (sp?) has a number of STC's for GA auto fuel

and some systems don't qualify as the stock system is

judged marginal with 100LL. My cherokee 180 fits this

description. I recall if vapor lock is suspected the

recovery is to apply > 75% power, full rich, with cowl

vents open, etc. and level flight or decent as able,

etc. Idea is to get more "cool" fuel from the tank to

an engine set up for a configuration that has max air

cooling. Pulling power might makes things worse as

line pressure drops.  Stock RV-10 config is low

pressure to the engine pump with a back up electric

(in a hot tunnel for some people)



There is a fuel temp where safe flight is not possible

- it would be good for the RV-10 crowd to work out

what that is and make sure there is a comfortable

margin.

When I test flew the 10 on April 21st and ordered my kit the guys at Van’s had just heard about it.  Whoever’s plane it was called to order a new gear leg.  Apparently that was the only part “tweaked” in the incident.  I think they said it was one that was built by a guy in California and then sold?  Tough to say if I have the story right cause I was still grinning from ear to ear after the “launch” off the runway in 410RV.

It was not me on the off field but I have been running mogas exclusively the last four hours.Would be concerned with vapor lock issues relative toflight conditions.

 So how many of us have logged time in 410 Romeo Victor?

How many of us are almost done building and have never flown in a -10 at all?  (Time for transition training!)

Other than a somewhat odd stall characteristic (somewhat sharpish break to the left and initial nose down, even with some hard right rudder peddle...and one could go into a stall spin from that point if you're not quick to recover or so it felt) compared to Cessna/Piper it handled like most planes I've flown...but very smooth and gentle in the flair, acceleration very good, good ground handling with a lively rudder instead of toe tappingas in a Tiger, the RV 10 rudder is more responsive IMHO that other castering nose wheel planes I've had the pleasure to fly.  But this is only my impression as the flight was fairly short and so was ground handling but I'd give it very good marks, none the less.

I’m lucky as Alex Dominicis is sanctioned by Van, lives about 20 miles from me, AND he has air conditioning!  Woo hoo!  Of course not all insurance companies have sanctioned him yet. D’oh!

Just got home from a week long trip for work. Wasn't me, although I haven't been to my hangar to see if my airplane is still there!! Don't think it would have been Al Cook (my airport) as I don't think his fly-off hours are done yet. My last name is actually "Chamberlain" for who ever cares. Mark (N104ML)

I heard through unnamed sources that it was an RV-10 involved in an off field landing near Paso Robles, CA. No injuries (except to a squirrel hole), some damage to wheel fairings and possibly a gear leg. Name of pilot not known as they are not affiliated with any list or group. Apparently, those involved in the investigation ( possibly Vans) are aware that we all want info about the cause as soon as it is available. At this point it sounds like it is engine related, not aircraft or system specific. I'm sure those involved will share any information with us should it be  determined that the cause relates to the design or construction of the 10 or is operating specific to the 10. Mark.
