| Subject: | History of 500A wing spar problems. |
Folks,
I'm not kidding, Steve Swift from CASA really does ride a bicycle,
I'll bet he isn't too happy riding the railroad, wheels and tracks
fatigue, bridges crack, even the odd cave roof falls in when the
rupture modulus of the local mountain is exceeded.
What we all have to understand is that "life" is the problem, it's a
sexually transmitted terminal disease.
I knew about all this, and still bought my 500A.
Cheers,
Bill Hamilton

Folks,
To keep things in perspective, if you examine the databases, world
wide, FOR ALL TYPES, it make interesting reading. Another US type
that features prominently is the Beech 18, but the total number of
in-flight failures of DeHavilland built aircraft is interesting, from
the Chipmunk, through the Dove and Heron, and finally the Trident jet
--- not necessarily in flight failures ---- but picked up in routine
maintenance.
With the Aero Commanders, the problem was/is the cold bent extrusions
---- but ----- with the AD's up to date, and properly conducted
inspections-----
RE. Australian experience, the local experts are a company called
General Aviation Maintenance, Steve Nott, and you should see the
wonderful aeroplanes that come out of his hangar (his is a
Renaissance centre), and I have lost count of how many various 500B/S
etc and 690 he actually owns and operates in his own right, or leases
to other operators, somebody recently quoted 20+.
Again to keep things in perspective, despite the "apparent" record,
the majority of aircraft owned and operated by DCA/DoA/CAA were Aero
Commander, variously small fleets of 560E, through 695.
As I said in a previous message, I knew all this, and still bought
ZK-DCF, I do have some corrosion rectification to do, but it is all
in the lap joints or the ribbed skins.
Cheers,
Bill Hamilton

I got most of the parts from a Shrike that it was removed from. I have all
the paperwork and drawings. It is available from Century.
