Well, the point I'm trying to make is that if you stay with the so called tried and true you should have less problems, which would mean that any Lycoming/Continental powered apparatus should be trouble free which, if you care to look, they aren't. The joke ought to be on the relics that still haven't managed to build decent quality engines or airframes.
I would expect the Diamond/Thielert combo to have more teething problems than a brand new Cessna with the same basic stuff they've been using for years. Yet, these old designs are not much better in fact.
Just one AD of this year: You'd think they had their design all figured out by now, or?
AD NUMBER: 2008-03-02
MANUFACTURER: Cessna
SUBJECT: Airworthiness Directive 2008-03-02
SUMMARY: We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 172R and 172S airplanes.
This AD requires you to inspect the fuel return line assembly for chafing; replace the fuel return line assembly if chafing is found; and inspect the clearance between the fuel return line assembly and both the right steering tube assembly and the airplane structure, adjusting as necessary.
This AD results from reports of chafed fuel return line assemblies, which were caused by the fuel return line assembly rubbing against the right steering tube assembly during full rudder pedal actuation.
We are issuing this AD to detect andcorrect chafing of the fuel return line assembly, which could result in fuel leaking under the floor and fuel vapors entering the cabin. This condition could lead to fire under the floor or in the cabin area.
