Chris,

No necessarily. Remember Turbine Jets are required to have working rudders, have brakes and a sign off of pilot ability. Jets, on the ground, will generally cause LESS damage to soft tissue than a spinning prop.

At Jet events, the spectators are much farther away than I think most people realize. Anyone in the pits is no longer a spectator. They should be a pilot (flying or not), part of a crew helping the pilot or ave signed off to understanding the risk (photographers, etc). Most every event I've been to does not allow spectators in the pits

Mark,

You're right about ground operations. The safety zones are probably adequate. Most pilots and aircraft are up to the task. I guess I'm more concerned about in-flight hazards. At some meets I've been to the flight paths are very close to the pits and therefore very close to the spectator line.
In addition, at more than one meet I've seen a mix of crew, pilots, and family members/friends all mingling in the pits too. I agree most meets don't allow spectators in the pits, but they are there anyway. The issue may not really be safety zones, but rather people control or lack of.

I hardly think Moms or Dads with toddlers, baby carriages, 12 year olds carrying balloons, cotton candy tripping over model jets, would qualify as crew. Often I see them with pit passes too. They are unsuspecting (and uncontrolled) spectators. I don't go to more than 3 or 4 meets per year, but I have seen this scenario at the majority of those meets. How often do we see the spectator line spread out along the length of the runway? Almost always Mom and Pop set up the lawn chairs closer and closer to the edge of the runway the further away from the show center they get. Hmmm...right where the jet is at a critical point in the approach or takeoff too.

For the record, I've seen this at prop events as well.
The CD has a challange. Keeping it fun for everyone, giving folks their money's worth, and safety. That's why they are paid the big bucks

We reply in this area because we are trying to avoid scenes like this. I understand your view. It definitely wasn't something with the turbine, but we are handling aircraft in smaller tolerances and must be aware of these occurrences.

I have a question for the safety minded folks-

If one was to overhaul the safety program at an RC club that has several jets, pylon races, etc - what are, lets say, the top three things that have been done in the last 5 years that have been deemed as an improvement to safety that also allow flexibility in flight operations?

Or - are we still doing things the same way for the most part?

I assume some of the larger clubs that host large events are probably more progressive in implementing new ideas, etc. However, necessity is the mother of invention as we say, so I'm sure good ideas exist everywhere regardless of size based on individual circumstances.

Well, heres another incident which proves that safety awareness and close inspection of our jets is vital. In preparation for this weekends meeting I have spent today meticulously checking my Mig 29. Everything checked out fine , flight controls , engine failsafe settings, and hydraulics for leaks etc. Usual stuff. Fuel system undisturbed sincle last time but just an engine run to check them out as the engines themselves had been out.

No 2 engine, fine. No 1 engine, left, slow to ramp and would not reach full rpm. Shortly afterwards fuel seen dripping from cowl.
Investigation revealed that the pressure line from pump to cutoff valve was not over even the first barb and was quite loose. Nothing has been touched since installation so it must always have been this way and the engines have been run many times without any problem. However the fuel line (Festo) has aged and lost what grip it had, result could have been a serious fire. Yes, it was my fault that the fuel line was not over the barbs but perhaps this can be a "heads up" for anyone who uses unbarbed fittings, such as some tube joiners like 3-4mm. Festo tubing WILL age over time and can lose its grip so if your fuel lines are of some age you may care to give them a close inspection, particularly if you used any unbarbed fittings in the pressure lines. Might save you a fire.

Regards, David Gladwin.

Only points out the obvious, David......that shut-offs/any filters/Tees, etc., ought only to be on the pump feed side...w/ a straight shot/no breaks in the pressure line. I.e., pump-to-engine as directly as possible.

We use all manner of Festos...never had a problem w/ this configuration......and any possible air bubble introduced, due to a bad connection, is usually obvious before flight upon inspection (though I've never had one)....and HAS to be better than the situation you potentially had on your hands

The pilot landed fairly quick after that, I sure hope he was ordered to and sent packing.
The bump that turned the plane toward the pits was in the first few feet of the take off roll and it could have easily been aborted, taxi around and tried again.
There was absolutely no reason to continue the takeoff through the pits/ready area.

i second that, did you notice where the pilot was standing?

We had a club member killed by an RC plane in 1981. Was a 60 size plane that hit him in the side and ruptured his liver.. He died in the OR.

hi this flight should of been stopped before he nearly killed at least 5 people the guy that dived on the deck would off been the first and this should also been kept local and not put out for every one to see, thats the reason we dont want d*"kheads flying jets its bad for every one no matter if you fly in the usa or the uk or the rest of the world i dont no what rules you fly to in the usa but this guy would not be flying jets here in the uk regards jonathan

STRUCTURAL INTEGRITY

This weekend in the UK, we had a really great jet meeting at RAF Cottesmore. There was only one crash and it really worries me . An ARF model had a wing disintegrate in flight, and crashed, fortunately clear of the pits in the grass, yet another structural failure of an aircraft from the same manufacturer of other airframes which have failed. A while ago I had to dodge another machine, same manufacturer, on which the stab. had failed, due to a poorly built structure. Several of us examined the wreckage and the internal structure was very poor, minimal, and a significant amount of the glueing had NOT met both surfaces, I have the photos to prove it beyond doubt. In addition the main spar was prevented from contacting the skin beacuse it was undersize, the TE spar preventing proper contact where the two meet.minimal structure, poorly executed.

As I personally own one of these machines, yet to fly, and found some serious structural deficiencies in the wing (now corrected) and know that some of the part of the internal structure were totally undersized, others misplaced, and I have heard of several of these machines disintegrating, I have an interest.

The one at Cottesmore, was recent version, so the problem seems to be ongoing. The question is this: As we KNOW there is a problem what are WE going to do about it ? Do we wait until a possibly very serious incident/ accident occurrs or do we start to fully report such occurrences to bring pressure on the manufacturer to get this aspect of his act togther.

If nothing is done and we bury our heads in the sand, continue with this game of Russian Roulett, afraid of upsetting the manufacturer or incurring his displeasure, we are merely contributing to, even exacerbating, the problem. If there IS a serious accident the future of the whole hobby may be in serious jeopardy.

Please discuss.

Regards,

David Gladwin.

Well put. However, under these uncomfortable circumstances, there is no reason why you should hide which manufacturers is responsible for this.

You mentioned "Structural Integrity" but said nothing as to what type of A/C or mfg. Why the silence ? In other threads you mentioned the problems with the BVM kingcat. SAFETY ISSUES should not be kept quiet
as they can only hurt the hobby.

I agree. Thank you for gathering and analyzing all of the information. Now it's time to allow the mfg the chance to correct the problem. I would think it would be in everyone's interest including the company fabricating the models to know that there are 'issues' in their production facility.

Just my opinion.

I do know what the model was i saw it break up, i also examined the wreckage, all that David says is true.
As David made the first post on this i feel it is up to him to 'name' the model and manufacturer.
