Preliminary report from media
Wing came off in two pieces. Questioning fatigue of the airframe.

The first link, from Tampa Bay Online, questions whether the aircraft might have had the wing extensions that have led to wing failures and are the subject of a recent AD, but the picture seems to show no wing extensions.
I am researching the FAA's Service Difficulty Reports (SDRS) we compiled on structural matters for the SID analysis to see if we can determine how many hours on that airframe. Ernie |

The wing appears to have separated at the rib just outboard of the tanks, where the wing extention AD says to look for smoking rivets.

I don't quite undertand it all. I keep flying my non modified skymaster within the maintenance, weight and speed parameters as provided in the POH and associated FAR's, and I simply can not make my wings fall off. I must not be trying hard enough !

Ernie, I have a note in my history for this bird, with TTIS of 5300 hours, about 2002.

There's two things I find very interesting in the picture, 1. is the aileron 2. is the "saw toothing" of the spare. The aileron outboard side appears ripped; that certainly could have happened upon impact with the ground, but an investigator must determine the cause of the rip. The spare doesn't have a clean break...the saw tooth pattern may suggest preexisting cracks...I'm sure the investigator will dedicate great analysis resources to the spare.
Perhaps its time for Cessna to start buying back the airplanes...just like Beachcraft once did. Better yet, an Obama bail out. |

After reading the report, I noticed it was night IMC, with cumulus cloud activity. I know the pilot was IFR rated, but vertigo can happen to any of us, myself included, not to mention the likelyhood of vertical drafts strong enough to fatigue a wing. From my analysis, night IMC is the #1 denominator amongst Cessna accidents. This may seem insensitive, but I wouldn't be surprised if the pilot is named as causal.
