How long do you think it would take to get changes made to 103 especially since the FAA has emphatically claimed that 103 would not be changed? Most likely not until long after the deadline has passed. If you own a fat ultralight, you had better take the 2007 deadline seriously or you may be sorry you didn't. A little birdie whispered in my ear that the weight limit for FAR 103 will be raised to 330 lbs in about a year. -- FF |

Floats would get extra lbs. ....and 10 gallons of fuel. ......and no upper end speed limit. If they're going to fix 103, let's fix it right. Montblack |

The FAR 103 limits are set to minimize risk to bystanders in an UL accident. The limit on fuel, arbitrary though it may be is very unlikely to be changed as increasing it obviously increases the potential severity of a fire resulting from a crash. The upper speed and weight limits, together, limit the energy in a crash and of the two the speed limit is the more important. However, though I haven't seen statistics on it, UL accidents involving a collison at maximum horizontal speed seem uncommon. The more typical accident is a forced landing (near stall speed) due to engine failure. Accidents resulting from structural failure will typically result in the aircraft falling from the sky at most at terminal velocity in free fall, not a kamikazee type dive to impact. So even though raising the speed limit would make ULS inherently more risky to the public one would expect only a minimal opportunity for that risk to be realized. Of the FAR 103 restrictions the one I would most like to see relaxed is the upper speed limit. That could give ULs some limited practicality for cross country flight. Consider the moni motorglider, barely over the FAR 103 weight limit but with a cruising speed up to 120 mph. Now, the moni has its problems but it showed that a plane within the weight limits of FAR 103 could have real cross country speed. Without an upper limit on speed, you could have UL pylon races. What a blast! Actually, you could have a rule limiting prop pitch since a rule limiting speed per se would not be practical. -- FF |

330 would do very nicely, thank you very much!
Electric start and brakes even! What did the little birdie say might be the motivation for this gracious action on behalf of the Friendly Aviation Agency? Do the fat ultralights represent that much of an economic or political impact on our economy? Hey, they are about the only thing that _is_ manufactured here anymore... Richard |
