A good friend is grieving the sudden loss of another friend from a plane
crash about a week ago. Neither the pilot nor the sole passenger survived. With very little information to go on with... I'm wondering what could have had been the possible factors into such an accident. I am sure the NTSB will do a good job in about 12-18 months from now when the final report is released. However, I'm still curious about the possibilities, and trying to make some head and tail of it all. Situation: pilot departed Portland, Oregon in his 1983 Glasair with destination being Crescent City, CA (CEC) around 12:30 am local time. Shortly after 2am local time, Seattle ATC reportedly received word from the pilot indicating he had CEC in visual sight and was terminating radar service, and switching to the local airport frequency. That was the final transmission received. Sounds like he had flight following? NTSB indicates he hadn't filed a flight plan so he had to be flying VFR. The authorities later determined the plane crashed in the ocean right by the Oregon and California border, about 700 yards off shore. The place is about 20-something miles away from CEC? Preliminary NTSB report indicates that at 0156 local time, at CEC: 1. VMC conditions prevailed -- clear at 10 statue miles 2. Wind was 110 degrees at 5 knots 3. Temp was 12 deg C, dewpoint was 5 deg C Final radar contact was lost at 0204, when the plane was at 400' AGL. Radar data indicates that 'the target' [as the NTSB put it] was descending at an high rate prior to the final radar contact. So my questions: 1. Would it have been possible for a pilot to see a destination airport from about 25 nm out, at night? I don't have much night flying experience. On the east coast, it's not easy to see places that far out at night... but that's mostly due to *all* the lights on the ground! 2. Is it possible the pilot might have seen lights reflecting off the water and misinterpreted it as runway lights? 3. If #2 is possible, could the pilot have had dived to 'make the runway'? I seem to recall that with night flying, it's easier to misjudge height. 4. Rapid descent -- a possible stall/spin? Uncoordinated flight, slowing down, maybe a change in AOA without benefit of a visible horizon to warn brain? Aka 'a graveyard spiral'? 5. Engine failure (fuel, mechanical) or carb icing due to shock cooling? I'm skeptical of this one because the trained pilot will ordinarily immediately set up for best glide speed and only maneuver as necessary. 6. Asymmetrical flaps situation? Seems somewhat unlikely because flaps wouldn't have had been deployed until late in the downwind leg by the destination runway. 7. Could the pilot have gotten lost, misunderstood current position, or just gotten confused, and mistaken the area for CEC? From my understanding, the pilot's home airport may have had been CEC. If that was the case, then he would probably be more familiar with CEC+vicinty flying and possibly including night flight? 8. CFIT? Hitting a tower/antenna or mountainous/cliff terrain? I'm not familiar with places out west, though I understand that terrain is a very real issue. But if the plane crashed in the ocean... hard to see how it could be terrain related. Granted, it wasn't too far from shore -- about 700 yards. I don't have a Klamath Falls sectional... alas. I know there's some r.a.p folks here that either lives in the region or are pretty familiar with the region. 9. Airframe icing doesn't sound too likely since there was no report of that from other pilots in the area at time of the crash. 10. Wind shear doesn't sound too likely. Wasn't really windy on the ground at CEC; unlikely to be significantly different only 20nm away along the coast? 11. Does the Glasair have special handling characteristics that someone not familiar with it might need to pay attention to? 12. The NTSB didn't specify the rate of descent, but their choice of wording ('rapid') suggests an higher than normal rate of descent. Does this sound like establishing for best glide to anyone? Or like a really serious problem? 13. Sudden debilitating medical condition seems unlikely because the pilot was 27 years old and not known to have any preexisting serious health issue. 14. Other possibilities? I do know for sure the pilot owned this plane. Considering his age, I find it unlikely he was the original owner. I do not know his total time (flight hours) nor hours in the Glasair. I understand the Glasair is a pretty nice plane, in general. I do not know the cruise altitude he flew at. They might know that one based on radar returns, but if they do, they didn't say so in the preliminary report. I understand the NTSB got its preliminary data from both FAA and U.S. military radar data. Not so sure it's necessarily plane's fault like the family and friends seems to think -- odds in general aviation are pretty good that it's often human error somewhere in the chain. I am accepting that while not pleasant, these things do happen despite the best of efforts made to prevent it. I know, understand, and appreciate the risks. I understand survivability was not real good -- reportedly 50 degree F water at the time of crash, though a local newspaper described the water as being 'icy'. No idea if hyperbole or fact... but either way, the passenger was recovered about 6 1/2 hours later. I doubt one could have had survived that long without any additional protection. (Neither person made it.) The family and friends, not being as familiar with aviation, are taking it much harder. So I'm hoping to be able to converse more intelligently once whenever they're ready to start asking questions about aviation related matters and the crash. Anyway... any comments would be much appreciated. -Dan |

Sorry for the loss of your friend. Could have been just about any of the things you mention, or a combination of several; we may never know, of course. Still, if I were betting, my money would be on simple spatial disorientation as the cause. Very easy to lose one's bearings over water at night, even when it's good VMC. Even over land, one can get out of shape from visual illusions very easily. The only time I ever came close to killing myself in an airplane was in the pattern at a rural airport on a nice, VMC night. Turning base, I looked at the airspeed indicator a moment and, when I looked outside again, got a false horizon off some ground lights and quickly overbanked the airplane. By the time I realized I had a problem--just a few seconds--I was within a couple hundred feet of the ground in a 60-deg. bank and descending fast. I had a moment of near panic as I realized I couldn't find the real horizon. The attitude indicator saved the day--er, night--but a few more seconds delay would have put me in the ground. -- Dan C172RG at BFM |

Was he instrument rated? Did the airplane have a GPS? If he had a GPS,
I doubt he mistook lights in the ocean for the airport. |

I doubt he was using flaps at 20 miles out, and it's no problem to see
the airport at 25 out also. It sounds to me like structural failure from what I read so far. |

I would say he was in a descent and well into the yellow arc. If he
reported in sight at 25 out, he would have to have some altitude. Five miles later would mean he had the nose pointed down and the airspeed way up, I usually do anyway 20 miles out - |

Radar data indicates that 'the target' [as the NTSB put it] was descending at an high rate prior to the final radar contact. My guess is spatial disorientation.

Would it have been possible for a pilot to see a destination airport from about 25 nm out, at night? Yes, very easily. At night, I have no problem seeing airports with arriving/departing flights from that distance even from 1,500 ft. Judging distances can be difficult on a clear night. I don't have much night flying experience. On the east coast, it's not easy to see places that far out at night... but that's mostly due to *all* the lights on the ground! You may be able to see them, but not discern the airport from the other lights. The tower lights may be more easy to find. 2. Is it possible the pilot might have seen lights reflecting off the water and misinterpreted it as runway lights? Hmmm. I wouldn't think so. Uncoordinated flight, slowing down, maybe a change in AOA without benefit of a visible horizon to warn brain? Aka 'a graveyard spiral'? That is very possible. Best regards, and condolences to your friends. Neil |

A few things come to mind:
First .. was he instrument rated? I know you said it was clear .. but could he have gotten into some scattered clouds or had some get between him and the city lights and lost control maneuvering by reference to instruments? Second .. a 22 yr old homebuilt composite aircraft. Structural failure? "Dan Foster" wrote in message ...

Take a look at:
http://www.landings.com/evird.acgi$pass*70934345!_h-www.landings.com/_landings/pages/search/certs-pilot.html If you know the pilot's name, you can see if he was instrument rated. |
