| Subject: | CKT silencer crack |
This damage looks difficult to repair by welding. The "collar" into which the exhaust
header tube is held with springs, has broken the weld most of the way around
where it attaches to the silencer box. There are other broken small welds
where the other header tubes get inserted.
Throughout the 300 hours total in the air since the silencer was first installed,
the carburettors have been kept electronically balanced and the Airmaster propeller
is also well balanced. The silencer was suspended with utmost care to
avoid strains as the flange nuts got tightened, making sure to tighten the telescopic
joint in #1 header tube last.
I'll probably have to replace the whole exhaust system. This topic is just FYI.
